Mp5 With Suppressor

HK MP5 9×19 submachinegun with Navy 3 Round Burst firing mechanism version, which features three-round cutoff. Widely acclaimed model of a submachinegun, primarily known as weapon of GSG9 and similar forces of the world, and famous through frequent appearance in movies and video games.Combine those three pieces, then remove the original HK MP5 9×19 upper receiver to replace it with the silenced one you just created. Then transfer the stock and the rearsight over from the old receiver as well.

While the MP5 reamins in limited use in the teams, these days a SEAL is more likely to carry a short barrel rifle such as the MK18 CQBR 5.56mmx45mm carbine.
The MP5K is produced (by Heckler & Koch and under license in Iran and Turkey) in four different versions: the MP5K, MP5KA4, MP5KA1, MP5KA5, where the first two variants have adjustable, open-type iron sights (with a notched rotary drum), and the two remaining variants – fixed open sights; however, the front sight post was changed and a notch was cut into the receiver top cover. The MP5K retained the capability to use optical sights through the use of an adapter.Threading is provided at the muzzle to work with certain muzzle devices made by Heckler & Koch, including: a slotted flash suppressor, blank firing attachment (marked with a red-painted band denoting use with blank ammunition only), an adapter for launching rifle grenades (for use with rifle-style grenades with an inside diameter of 22 mm using a special grenade launching cartridge) and a cup-type attachment used to launch tear gas grenades. An optional three-lugged barrel is also available for mounting a quick-detachable suppressor.

The MP5 has become a mainstay of SWAT units of law enforcement agencies in the United States since then. However, in the late 1990s, as a result of the North Hollywood shootout, police special response teams replaced most MP5s with AR-15-based rifles.
Since the 9×19mm Parabellum cartridge is relatively low powered, the bolt does not have an anti-bounce device like the G3, but instead the bolt carrier contains 32.5 g (1.15 oz) of tungsten granules that prevent the bolt group from bouncing back after impacting the barrel extension. The weapon has a fluted chamber that enhances extraction reliability by bleeding gases backwards into the shallow flutes running along the length of the chamber to prevent the cartridge case from expanding and sticking to the chamber walls (since the bolt is opened under relatively high barrel pressure). A spring extractor is installed inside the bolt head and holds the case securely until it strikes the ejector arm and is thrown out of the ejection port to the right of the receiver. The lever-type ejector is located inside the trigger housing (activated by the movement of the recoiling bolt).Heckler & Koch, encouraged by the success of the G3 automatic rifle, developed a family of small arms consisting of four types of firearms all based on a common G3 design layout and operating principle. The first type was chambered for 7.62×51mm NATO, the second for the 7.62×39mm M43 round, the third for the intermediate 5.56×45mm NATO caliber, and the fourth type for the 9×19mm Parabellum pistol cartridge. The MP5 was created within the fourth group of firearms and was initially known as the HK54. In 1992, Heckler & Koch introduced the MP5/10 (chambered in 10mm Auto) and MP5/40 (chambered for the .40 S&W cartridge), which are based on the MP5A4 and MP5A5. These weapons were assembled in fixed and retractable stock configurations (without a separate designation) and are fed from translucent 30-round polymer box magazines. These weapons include a bolt hold-open device, which captures the bolt group in its rear position after expending the last cartridge from the magazine. The bolt is then released by pressing a lever positioned on the left side of the receiver. Both weapons use a barrel with 6 right-hand grooves and a 380 mm (1:15 in) twist rate, and like the MP5-N, both have a 3-lugged muzzle device and a tritium-illuminated front sight aiming dot. The stockless MP5A1 has a buttcap with a sling mount for concealed carry; the MP5K series was a further development of this idea. The MP5A2 has a fixed buttstock (made of a synthetic polymer), whereas the compact MP5A3 has a retractable metal stock.The Heckler & Koch MP5 (German: Maschinenpistole 5) is a submachine gun which fires 9x19mm Parabellum cartridges, developed in the 1960s by Heckler & Koch. There are over 100 variants and clones of the MP5, including some semi-automatic versions. The MP5 is one of the most widely used submachine guns in the world, having been adopted by over forty nations and numerous military, law enforcement, intelligence, and security organizations.

In 1980, the MP5 achieved iconic status as a result of British special forces regiment the SAS when they stormed the Iranian Embassy in London, live on television, rescuing hostages and killing five terrorists during Operation Nimrod.
The MP5SD is produced exclusively by Heckler & Koch in several versions: the MP5SD1 and MP5SD4 (both have a receiver end cap instead of a buttstock), MP5SD2 and MP5SD5 (equipped with a fixed synthetic buttstock) and the MP5SD3 and MP5SD6 (fitted with a collapsible metal stock). The MP5SD1, MP5SD2 and MP5SD3 use a standard ‘SEF’ trigger group (from the MP5A2 and MP5A3), while the MP5SD4, MP5SD5, and MP5SD6 use the ‘Navy’ trigger group—a trigger module with a mechanically limited 3-round burst mode and ambidextrous selector controls (from the MP5A4 and MP5A5). A suppressed version was produced for the U.S. Navy—designated the MP5SD-N, which is a version of the MP5SD3 with a retractable metal stock, front sight post with tritium-illuminated dot and a stainless steel suppressor. This model has a modified cocking handle support to account for the slightly larger outside diameter of the suppressor. The design of the suppressor allows the weapon to be fired with water inside, should water enter the device during operation in or near water.The fixed, free floating, cold hammer-forged barrel has six right-hand grooves with a 1 in 250 mm (1:10 in) rifling twist rate and is pressed and pinned into the receiver.

Which suppressor on MP5?
When it comes to durability, performance, and ease of maintenance, the RYDER 9-MP5 is the clear choice for suppressing the MP5. Cached
The MP5A4 (fixed stock) and MP5A5 (sliding stock) models, which were introduced in 1974, are available with four-position trigger groups. The pistol grips are straight, lacking the contoured grip and thumb groove of the MP5A1, MP5A2, and MP5A3. The selector lever stops are marked with bullet pictograms rather than letters or numbers (each symbol represents the number of bullets that will be fired when the trigger is pulled and held rearward with a full magazine inserted in the weapon) and are fully ambidextrous (the selector lever is present on each side of the trigger housing). The additional setting of the fire selector, one place before the fully automatic setting, enables a two or three-shot burst firing mode.The first MP5 models used a double-column straight box magazine, but since 1977, slightly curved, steel magazines are used with a 15-round capacity (weighing 0.12 kg) or a 30-round capacity (0.17 kg empty).

The bolt rigidly engages the barrel extension—a cylindrical component welded to the receiver into which the barrel is pinned. The delay mechanism is of the same design as that used in the G3 rifle. The two-part bolt consists of a bolt head with rollers and a bolt carrier. The heavier bolt carrier lies up against the bolt head when the weapon is ready to fire and inclined planes on the front locking piece lie between the rollers and force them out into recesses in the barrel extension.
Aftermarket replacement handguards with Picatinny rails are available. Single-rail models have a Picatinny rail along the bottom and triple-rail models have rails along the bottom and sides. They allow the mounting of accessories like flashlights, laser pointers, target designators, vertical foregrips, and bipods.The adjustable iron sights (closed type) consist of a rotating rear diopter drum and a front post installed in a hooded ring. The rear sight is mechanically adjustable for both windage and elevation with the use of a special tool, being adjusted at the factory for firing at 25 metres (27 yd) with standard 8 grams (123 gr) FMJ 9×19mm NATO ammunition. The rear sight drum provides four apertures of varying diameters used to adjust the diopter system, according to the user’s preference and tactical situation. Changing between apertures does not change the point of impact down range.

The MP5 has a hammer firing mechanism. The trigger group is housed inside an interchangeable polymer trigger module (with an integrated pistol grip) and equipped with a three-position fire mode selector that serves as the manual safety toggle. The “S” or Sicher position in white denotes weapon safe, “E” or Einzelfeuer in red represents single fire, and “F” or Feuerstoß (also marked in red) designates continuous fire. The SEF symbols appear on both sides of the plastic trigger group. The selector lever is actuated with the thumb of the shooting hand and is located only on the left side of the original SEF trigger group or on both sides of the ambidextrous trigger groups. The safety/selector is rotated into the various firing settings or safety position by depressing the tail end of the lever. Tactile clicks (stops) are present at each position to provide a positive stop and prevent inadvertent rotation. The “safe” setting disables the trigger by blocking the hammer release with a solid section of the safety axle located inside the trigger housing.
The delay results from the amount of time it takes for enough recoil energy to be transferred through to the bolt carrier in a sufficient quantity for it to be driven to the rear against the force of inertia of the bolt carrier and the forward pressure exerted against the bolt by the recoil spring. As the rollers are forced inward they displace the locking piece and propel the bolt carrier to the rear. The bolt carrier’s rearward velocity is four times that of the bolt head since the cartridge remains in the chamber for a short period of time during the initial recoil impulse. After the bolt carrier has travelled rearward 4 mm, the locking piece is withdrawn fully from the bolt head and the rollers are compressed into the bolt head. Only once the locking rollers are fully cammed into the bolt head can the entire bolt group continue its rearward movement in the receiver, breaking the seal in the chamber and continuing the feeding cycle.

The primary version of the MP5 family is the MP5A2, which is a lightweight, air-cooled, selective fire delayed blowback operated 9×19mm Parabellum weapon with a roller-delayed bolt. It fires from a closed bolt (bolt forward) position.
In 1991, a further variant of the MP5K was developed, designated the MP5K-PDW (PDW—Personal Defense Weapon) that retained the compact dimensions of the MP5K but restored the fire handling characteristics of the full-size MP5A2. The MP5K-PDW uses a side-folding synthetic shoulder stock (made by the U.S. company Choate Machine and Tool), a “Navy” trigger group, a front sight post with a built-in tritium insert and a slightly lengthened threaded, three-lug barrel (analogous to the MP5-N). The stock can be removed and replaced with a receiver endplate; a rotary drum with apertures from the MP5A2 can also be used.

In the early 1970s, HK introduced a conversion kit for the MP5 that enables it to use rimfire ammunition (.22 LR). This unit consists of a barrel insert, a bolt group and two 20-round magazines. This modification reduces the cyclic rate to 650 rounds per minute. It was sold mostly to law enforcement agencies as a way to train recruits on handling the MP5. It used ammunition that was cheaper and had a lower recoil than 9×19mm Parabellum. This reduced training costs and built up skill and confidence in the operators before transitioning them to the full-bore model.A Picatinny rail adapter can be placed on top that locks into the claw rails. This allows the mounting of STANAG scopes and has a lower profile than the claw-rail system. The MP5SD was created in 1974, Heckler & Koch initiated design work on a sound-suppressed variant of the MP5, designated the MP5SD (SD—Schalldämpfer, German for “sound suppressor”), which features an integral but detachable aluminium sound suppressor and a lightweight bolt. The weapon’s 146 mm (5.7 in) barrel has 30 2.5 mm (0.1 in) ports drilled forward of the chamber through which escaping gases are diverted to the surrounding sealed tubular casing that is screwed onto threading on the barrel’s external surface just prior to the ported segment. The suppressor itself is divided into two stages; the initial segment surrounding the ported barrel serves as an expansion chamber for the propellant gases, reducing gas pressure to slow down the acceleration of the projectile. The second, decompression stage occupies the remaining length of the suppressor tube and contains a stamped metal helix separator with several compartments which increase the gas volume and decrease its temperature, deflecting the gases as they exit the muzzle, so muffling the exit report. The bullet leaves the muzzle at subsonic velocity, so it does not generate a sonic shock wave in flight. As a result of reducing the barrel’s length and venting propellant gases into the suppressor, the bullet’s muzzle velocity was lowered anywhere from 16% to 26% (depending on the ammunition used) while maintaining the weapon’s automation and reliability. The weapon was designed to be used with standard supersonic ammunition with the suppressor on at all times. The cyclic rate of fire of the MP5SD is around 700 rounds per minute. The MP5 is manufactured under license in several nations including Greece (formerly at EBO – Hellenic Arms Industry, currently at ΕΑΣ – Hellenic Defense Systems), Iran (Defense Industries Organization), Mexico (SEDENA), Pakistan (Pakistan Ordnance Factories), Saudi Arabia, Sudan (Military Industry Corporation), Turkey (MKEK), and the United Kingdom (initially at Royal Ordnance, later diverted to Heckler & Koch Great Britain).

In 1976, a shortened version of the MP5A2 was introduced; the MP5K (K from the German word Kurz = “short”) was designed for close quarters battle use by clandestine operations and special services. The MP5K does not have a shoulder stock (the receiver end was covered with a flat end cap, featuring a buffer on the inside and a sling loop on the outside), and the bolt and receiver were shortened at the rear. There are no MP5KA2 or MP5KA3 models because it does not come with a fixed or retractable stock. The resultant lighter bolt led to a higher rate of fire than the standard MP5 at around 900 rounds per minute. It has a shortened 4.5 in (114 mm) barrel, a shorter trigger group frame, the charging handle and its cover were shortened and a vertical foregrip was used to replace the standard handguard. The barrel ends at the base of the front sight, which prevents the use of any sort of muzzle device.In late 2013, Heckler & Koch unveiled the MLI (Mid Life Improvement) version of the MP5. It is fitted with a tri-rail foregrip, a quick-release-optic mount, an MP5F stock standard, and comes in with the new RAL8000 (Yellow-Brown) colour scheme.

The non-reciprocating cocking handle is located above the handguard and protrudes from the cocking handle tube at approximately a 45° angle. This rigid control is attached to a tubular piece within the cocking lever housing called the cocking lever support, which in turn makes contact with the forward extension of the bolt group. It is not however connected to the bolt carrier and therefore cannot be used as a forward assist to fully seat the bolt group. The cocking handle is held in a forward position by a spring detent located in the front end of the cocking lever support which engages in the cocking lever housing. The lever is locked back by pulling it fully to the rear and rotating it slightly clockwise where it can be hooked into an indent in the cocking lever tube.
The receiver housing has a proprietary claw-rail mounting system that permits the attachment of a standard Heckler & Koch quick-detachable scope mount (also used with the G3, HK33 and G3SG/1). It can be used to mount daytime optical sights (telescopic 4×24), night sights, reflex sights and laser pointers. The mount features two spring-actuated bolts, positioned along the base of the mount, which exert pressure on the receiver to hold the mount in the same position at all times assuring zero retention. All versions of the quick-detachable scope mount provide a sighting tunnel through the mount so that the shooter can continue to use the fixed iron sights with the scope mount attached to the top of the receiver.

A variant with the last trigger group designated the MP5-N (N—Navy) was developed in 1986 for the United States Navy. This model has a collapsible stock, a tritium-illuminated front sight post and a 225 mm (8.9 in) threaded barrel for use with a stainless steel sound suppressor made by Knight’s Armament Company together with quieter subsonic ammunition. It had ambidextrous controls, a straight pistol grip, pictogram markings, and originally had a four-position selector (Safe, Semi-Auto, 3-Round Burst, Full Auto). This was replaced with a similar three-position ambidextrous selector after an improperly-reassembled trigger group spontaneously fired during an exercise. The “Navy”-style ambidextrous trigger group later became standard, replacing the classic “SEF” trigger group.

Heckler & Koch offers dedicated training variants of these weapons, designated MP5A4PT and MP5A5PT (PT—Plastic Training), modified to fire a plastic 9×19mm PT training cartridge produced by Dynamit Nobel of Germany. These weapons operate like the standard MP5 but have a floating chamber and both rollers have been omitted from the bolt to function properly when firing the lighter plastic projectiles. To help identify these weapons blue dots were painted on their cocking handles and additional lettering provided. The PT variant can be configured with various buttstocks and trigger groups and was developed for the West German Police and Border Guard.
When fired, expanding propellant gases produced from the burning powder in the cartridge exert rearward pressure on the bolt head transferred through the base of the cartridge case as it is propelled out of the chamber. A portion of this force is transmitted through the rollers projecting from the bolt head, which are cammed inward against the inclined flanks of the locking recesses in the barrel extension and to the angled shoulders of the locking piece. The selected angles of the recesses and the incline on the locking piece produce a velocity ratio of about 4:1 between the bolt carrier and the bolt head. This results in a calculated delay, allowing the projectile to exit the barrel and gas pressure to drop to a safe level before the case is extracted from the chamber.Work on the MP5 began in 1964 and two years later it was adopted by the German Federal Police, border guard and army special forces, referring to as the “MP64” or later “MP5”. The MP5A1 was introduced in the late ’60s, which is the first model to have the iconic ring front sight and the slimline handguard. In 1970, the MP5A2 and MP5A3 were introduced. In 1974, the MP5SD was introduced, which is a suppressed variant of the MP5. It was used in the Vietnam War in 1975 by the Green Berets. In 1976, the MP5K was introduced as a request for a variant for South America. In 1977, the standard 20 & 30 round, curved steel magazines were introduced for the MP5A2 and MP5A3 design. In 1978, the Tropical forearm was introduced to be produced with the MP5.

Post sample MP5 machine guns are the most common option. They are reserved for law enforcement, military, and limited sale samples to 07/02 FFL’s. However, once the owner is no longer licensed, the firearm must either be destroyed legally, dismantled into a parts kit, or transferred to the government, military, or other type 07/02 FFL.
If you are looking for a fully automatic MP5 there are transferable NFA registered MP5’s on the market that, at the time of this article, start around $40k. As a civilian, you can legally purchase one of these MP5’s, all you need is the money and some paperwork.The rarest and most desirable are transferable MP5 machine guns that any civilian can own (requires deep pockets, a $200 NFA tax stamp, a background check, and a lot of patience waiting for the ATF’s blessing).

The second MP5 option is a pre-dealer sample. Pre-dealer samples are reserved for Type 07/02 FFL’s (Federal Firearm Licensed dealers authorized to deal in machine guns). These are reserved for federally licensed machine gun dealers that can be transferred to the licensee’s ownership even after they are no longer licensed.
The short answer is yes. Civilians can own an HK MP5 variant. Heckler & Koch currently offers the HK SP5, a semi-automatic version of the original select fire MP5. They also offer a shorter version of the SP5, the SP5K, a longer version, the SP5L, and just recently, a .22 long rifle version, the MP5 .22LR Pistol. There are also many clone offerings on the market that are completely legal for you to buy and own as a civilian. These clones include MKE, PTR, and other custom builds.

So, if you’ve ever wondered, can you legally buy an MP5, the short answer is yes. Civilians can legally own an MP5 and there are several ways for you to go about doing so. Obtaining an MP5 can be a complex process so it’s important to check the rules and regulations in your area before getting your hopes up.
I got scammed on this one. First of all, I got mine in literal pieces even though it said it was a complete gearbox. Also it said it was wired but it was doubleended with moter wires and no metal nozzle. Can’t be arsed sending it back so am just going to use the partsI bought this for one of my surefires to use on a retro build. Didn’t have much faith for $10 but so far it is decent. Has bright and low mode but nothing to lock the lights in the on mode. It ships from China but got to me in Florida in about a week. Time will tell on how it holds up.

The MP5-Adv comes with an attached suppressor, a larger magazine capacity of 40 rounds (+10), and slightly higher damage. It also has a slightly more accurate and slightly faster reload speed. This makes the gun superior to other SMGs such as the MP7 and the P90.
Check out the content of CrossFire China’s next update! It includes a roguelike zombie mode map, Valor Beast set, Butterfly Knife-Luminous Edge and more!The SEALs primarily use the MP5 for Counterterrorism, Close Quarters Combat, hostage rescue, and personal protection operations. It is compact, concealable, durable, maneuverable and hard-hitting. It is easily controllable and the recoil is extremely smooth, allowing the shooter to obtain highly accurate shot placement. Depending on the mission, the MP5 may be operationally used in conjunction with the M4A1, for increased firepower. H&K has an MP5SD model for missions where stealth and secrecy require fully-integrated sound suppression. It also makes a version called the MP5K Machine Pistol, which weigh only 4.4 lbs, is less than 13 inches in length, and can be fired from inside a specially designed briefcase. This variant has three firing modes – semi, three-round burst, and full automatic.The MP5N Navy Model, developed by H&K especially for the U.S. Navy SEALs, fires from a closed and locked bolt in either the semiautomatic or automatic modes. This provides superior accuracy, especially critical on the first shot, which can mean the difference between life and death. The MP5 fires a 9mm parabellum round in single shot fire, three-round bursts, or full automatic at 800 rounds per minute. It has a retractable buttstock, a removable suppressor, and illuminating flashlight operated by a pressure switch that is custom-fitted to the pistol grip.

Does the MP5 have a built in suppressor?
The MP5 Submachine Gun (Weapon) The MP5SD’s barrel-and-suppressor combination cuts the speed of the round to subsonic velocity. The suppressor reduces peak muzzle noise to approximately 70 decibels, roughly the same intensity as a loud human voice. Cached
The Navy SEALs and many other elite counter-terrorist units around the world – to include the British SAS, Germany’s GSG 9, and Spain’s GEO — use the compact submachine gun. What’s unique on this automatic machine gun is the roller-delayed blowback system which operates the weapon in a fully locked breach position. Where other automatic systems rely on the weight and velocity of the returning breach to seal the chamber the MP5 does this through a series of locks and cams.The MP5 was first used by GSG-9 in action against terrorists who hijacked a Lufthansa aircraft on October 17, 1977 and flew it to Mogadishu, Somalia. It was also prominently displayed in pictures of the SAS takedown of the terrorist-held Iranian Embassy in 1980. The MP5 has also seen action in U.S. operations such as the Grenada and Panama invasions.

The SWAT Operations Unit (SOU), part of the Critical Incident Response Group, oversees the FBI SWAT program. The SOU is responsible for developing standardized training, procedures and tactics, and for research and development including equipment, for the SWAT teams to ensure interoperability for multiple-office deployments. During multiple-office deployments the SOU provides planning assistance and oversight. SWAT teams train on average 32 hours a month.FBI SWAT also appears in several video games, such as SWAT 4 (2005), Payday 2 (2013), Tom Clancy’s Rainbow Six Siege (2015), Tom Clancy’s Ghost Recon Wildlands (2017), Tom Clancy’s Ghost Recon Breakpoint (2019), and Ready or Not (2021).

FBI SWAT teams are specially trained to serve warrants and intervene in high-risk incidents such as active shooters, barricaded suspects, or protection for personnel or dignitaries.

The Firearms Unit at the FBI Academy began developing SWAT teams in the early 1970s. Following the Wounded Knee Occupation in 1973, the FBI established a regional SWAT program to organize SWAT teams and provide qualified command personnel.
Nine FBI SWAT teams are designated as “Enhanced” SWAT teams and are specially trained to be able to assist/augment the full-time national Hostage Rescue Team if needed. Enhanced SWAT teams are typically located at larger field offices and comprise a larger number of personnel than standard teams, in addition to having increased access to additional tactical equipment and methods.FBI SWAT uses a variety of armored SWAT vehicles, including the Lenco BearCat, Humvee, various MRAP models, and occasionally tracked armored personnel carriers. A variety of civilian-style vehicles are also used when necessary (such as to avoid attention), often unmarked SUVs, vans, or pickup trucks produced by subsidiaries of Ford, General Motors, and Stellantis.FBI SWAT teams are trained to a national standard and utilize the same equipment which enables a team to provide assistance to another Field Office Team. SWAT teams can be dispatched to aid local law enforcement with limited resources to manage large-scale high-risk incidents.In film and television, FBI SWAT appears in films such as Face/Off (1997), The Town (2010), S.W.A.T.: Firefight (2011), and S.W.A.T.: Under Siege (2017), and television shows such as FBI, Criminal Minds and The Blacklist (2013).FBI Special Weapons and Tactics Teams are specialized part-time tactical teams (SWAT) of the Federal Bureau of Investigation (FBI). The FBI maintains SWAT teams at each of its 56 field offices throughout the United States. Each team is composed of a varying number of certified SWAT operators, dependent on office size and funding.

FBI SWAT is known to use the M4 carbine, Heckler & Koch MP5/10, Remington 870, Remington 700, various Glock models (17 Gen4, 19M, 20), SIG Sauer P226, and Springfield Armory 1911 Professional Custom.In this review, the Otter Creek Labs Lithium performance metrics depend upon suppressing a subsonic centerfire pistol cartridge on a roller-delayed blowback submachinegun.

Bolt-action weapons allow for the elimination of variables to study pure sound signature suppression phenomena. PEW Science is continuing bolt-action and automatic rifle weapon testing, analysis, and research. The purpose of this Public Research Supplement is to present a first-look at muzzle blast phenomenology for a new addition to the published host weapon systems in the Standard; the so-called “pistol caliber carbine,” (PCC), or submachinegun, chambered in 9x19mm NATO. Shooting suppressed can cause a gun to heat up faster than it would normally. For most shooting situations, this isn’t a huge issue. However, full-auto fire from a machine gun generates a lot of heat in its own right, so adding a suppressor into the mix really turns up the heat. Brandon Maddox, CEO and owner of Silencer Central, is recognized as a national thought leader on Class 3 firearms.

Does swat still use MP5?
FBI SWAT is known to use the M4 carbine, Heckler & Koch MP5/10, Remington 870, Remington 700, various Glock models (17 Gen4, 19M, 20), SIG Sauer P226, and Springfield Armory 1911 Professional Custom.
Anyone who has ever shot suppressed or shot a machine gun has undoubtedly walked away thinking, “man, that was awesome!” Some may then have been led to wonder, “can you suppress a machine gun?” Because, well, let’s face it. The only thing cooler than shooting suppressed or shooting a machine gun is shooting a suppressed machine gun.When people think of machine guns, they often picture large military weapons such as the M240 chambered for the 7.62 cartridge. It’s important to remember that there are also smaller machine guns, such as the M4 in 5.56 and even full-auto .22 rifles and pistols. Oh, and let’s not forget the ultimate in unobtainium machine gun fun: the Glock 18 full-auto pistol in 9mm.

Many of the military’s machine guns are equipped with the ability to easily swap out barrels. This is due in large part to the heat issue mentioned above. Of course, if you swap out the barrel, you’ll also need to swap out the suppressor, and that’s not going to be a pleasant task when the gun is at such a high temperature that the barrel needs changing. As a result, a suppressed machine gun with multiple barrels is going to need multiple suppressors so that one can doesn’t have to be swapped between the barrels.
Of course, this isn’t really a blanket statement as there are some caveats. We’ll take a look at both the benefits and disadvantages of using a suppressor on a machine gun.

With more than 15 years of experience in the industry, Silencer Central is the nation’s largest silencer dealer. We’re also the only one licensed in all 42 suppressor-legal states that can sell, process, and ship your new suppressor directly to your front door. We’ll set you up with a free gun trust, mail you the necessary fingerprint cards, and even arrange a no-interest payment plan so that you can pay while you wait for ATF approval. It doesn’t get any better – or easier – than that!

With the understanding that machine guns are much more than just big guns in big calibers, the question of suppressing a machine gun can become simpler. So the short answer is yes, you can use a suppressor on a machine gun.The most obvious applications for suppressed machine guns lie with the military. The Army has been conducting tests with suppressors on the M240 machine gun and the Marine Corps has even gone so far as to begin testing the mighty .50 caliber M2, or “Ma Deuce.” In between there, JSOC has been working with suppressors on medium machine guns.

We all know that a suppressor doesn’t make a gun silent, especially if it’s shooting a large caliber and/or using supersonic ammunition. Nonetheless, a suppressor does still quiet down the sound of a gunshot, even on a machine gun. Because you’re sending more rounds downrange faster than normal, that extra bit of hearing protection is definitely a huge plus to shooting a suppressed machine gun.
Where there’s good, there’s also bad, and suppressed machine guns are no exception. The benefits of suppressing a machine gun are great, but it’s important to consider the disadvantages of suppressing a machine gun before making the final decision. Here are a few disadvantages to consider.Before his work with Silencer Central, Maddox practiced pharmacy and served as a marketing executive in the pharmaceutical industry.

If you’ve ever shot in low-light or no-light conditions, then you know just how bright a gun’s muzzle flash can be. Another added benefit of shooting suppressed is that you’ll notice a reduction in the amount of muzzle flash. This can be very beneficial when you’re shooting a machine gun and those rounds – and the accompanying muzzle flash – are appearing faster and more frequently. Your eyes will appreciate the reduced strain.Recoil is the bane of every shooter’s existence, but one of the added benefits of using a suppressor is that you will often notice a reduction in the amount of felt recoil. Whether you’re shooting a .22 caliber machine gun or something more substantial, you’ll appreciate the recoil reduction as it’ll help you keep the firearm on target. Designed for smaller, center-fire calibers, the Banish 223 will fit all rifles .224 and smaller. With a 34db sound reduction, the Banish 223 is below hearing safe. We’ve talked at length in other blog posts about the benefits of using a suppressor on bolt-action and semi-auto firearms, but there are also a lot of benefits to suppressing a machine gun. Let’s take a look at a few.OK, so you probably don’t own a machine gun. Most people don’t have the money or the proper FFL/SOT to have one. That’s OK. There are still plenty of reasons why you should buy a suppressor.

How much does a suppressed MP5 cost?
The silencer cost would be negligible if you are already able and willing to shell out for a fully auto MP5. You’d be looking at a basic price tag of say 35K to 40K+ nowadays. The suppressor would just be a few more grand (the tube itself and your ATF stamp).
However, the idea of suppressed machine guns within the military is still in its infancy. There will need to be a lot more testing and evaluation before a determination is made as to whether or not suppressed machine guns will become a mainstay in the modern military arsenal.

The main variants MP5, MP5 SD and MP5 K in their respective individual configurations show what classic submachine guns in calibre 9 mm x 19 can deliver today. The MP5 is primarily aimed at police units and first response forces engaging area targets. Easy to handle, easy to control and uncompromisingly precise in an emergency. The MP5 SD, on the other hand, fulfils the weaponry requirements of specialised forces and selected special units. What distinguishes it from all submachine guns available on the market, however, is its special weapon barrel with integrated silencer. Where other submachine guns have to use special subsonic ammunition for silenced use, the MP5 SD fires supersonic ammunition in the subsonic range (<340 m/s). It is also one of the most precise silenced submachine guns in its class. As the most compact submachine gun in the MP5 family, the MP5 K is designed primarily for special forces and bodyguards. Effective in close-range defence and built so compactly that it can easily be carried concealed on the body.
We want people to be able to live safely. Our products are designed to protect people in free democratic countries from threats and violence. Heckler & Koch is the leading manufacturer of small arms for NATO and EU countries. Concluding from the increasing danger of amok and terrorist situations, effective measures were taken with the mid-life improvement of the MP5, which on the one hand take logistical and economic aspects into account, and on the other hand fulfil the tactical parameters required on the weapons side. The collapsible buttstock has been reinforced and equipped with three locking positions. This allows the MP5 MLI to be optimally adjusted to body armour or multi-purpose vests. The modern and slim HKey handguard replaces the conventional BMI polymer handguard, as the in-house HKey keyhole attachment system offers the best possible repeatability for mounted laser light modules in test comparisons. For the use of reflex sights suitable for night vision goggles, the MP5 MLI is equipped with a self-aligning STANAG 4694 clamping profile rail. Particularly cost-effective and logistically attractive: Suitable MLI components can be retrofitted to any MP5 model. Not only does the suppressor reduce the sound of the weapon, it also dissipates muzzle flash. Since its launch in the mid-1970s there have been six incarnations of the SD with various stock setups and trigger groups. The MP5SD continues to be popular with militaries and police forces around the world.The MP5SD quickly gained favor with tier-one special forces units, such as the British Special Air Service and Special Boat Service, U.S. Army Delta Force and the U.S. Navy SEALs — and has been adopted by military and security forces around the world.While all MP5s could be fitted with an external suppressor using the quick-detachable tri-lug system, this compromised the handiness of the weapon. With this in mind, H&K decided to develop a dedicated variant. The firm introduced the MP5SD in 1974. It boasts an integral suppressor and includes several other changes — such as a lighter bolt — to ensure reliable cycling. The MP5SD’s barrel-and-suppressor combination cuts the speed of the round to subsonic velocity. The suppressor reduces peak muzzle noise to approximately 70 decibels, roughly the same intensity as a loud human voice. The SD’s short barrel featured 30 2.5-millimeter ports in order to bleed off a significant amount of the propellant gases into the expansion chamber of the suppressor. This allows the volume of the gas to expand — and the pressure to drop — before the gas passes through the second chamber, which contains conical baffles and further reduces the weapon’s report.

In the early 1970s, Heckler & Koch began work on an integrally-suppressed variant of its extremely popular roller-delayed blowback submachine gun, the MP5. The company designated the new suppressed weapon the MP5SD, “SD” meaning Schalldämpfer or “sound suppressor.”
Unlike Walther’s add-on suppressor, the MP5SD’s integral suppressor minimizes additional length. The MP5SD’s suppressor is aluminum, which helps to keep down its weight and retain the weapon’s previous balance.In 1964 Walther, one of H&K’s main rivals, developed its own suppressors for its MPK submachine gun and P38 pistols. Walther was the first German arms-manufacturer to be granted a special permit for suppressor production. The MPK’s barrel configuration allows the suppressor to be used without impeding the weapon’s sights. These equipped West German intelligence agents — and may also have been issued to U.S. Special Forces stationed in Western Germany. One drawback of H&K’s early SD design was carbon build-up inside the suppressor housing and on the barrel, which — without regularly cleaning — would cause the suppressor to lock up. Funktionale Cookies sind für die Funktionalität des Webshops unbedingt erforderlich.

The suppressor attaches to a standard trilug barrel via our patented Fast-Attach mechanism, similar to the way our best-in-class SOCOM Series suppressors attach. Our patented stainless steel baffles are extremely durable and highly effective at attenuating noise, and built-in spacers help prevent excessive carbon buildup. The suppressor is easily disassembled for cleaning, and the baffles are indexed and numbered for ease of reassembly. Designed for duty use, the RYDER 9-MP5 does not affect bullet performance or increase point of impact/point of aim as is the case with other sub-machine gun suppressors. When it comes to durability, performance, and ease of maintenance, the RYDER 9-MP5 is the clear choice for suppressing the MP5.

What suppressor do Navy SEALs use?
Surefire suppressors have been serving at war with U.S. Special Operations Command (SOCOM) for more than a
Call it a suppressor, a silencer, or a can, it’s the same thing – and one of the most common questions about our American-made MP5 is “Can you shoot the ZF-5 with a suppressor?”We recommend cleaning your suppressor and ZF-5 every 500 rounds, if not more frequently. Be sure to take care to thoroughly clean the suppressor and barrel as more carbon and metal fouling will accumulate when shooting suppressed. Use a high-quality solvent and be sure to remove all fouling and residue while cleaning.After the firearm and suppressor have cooled off adequately, remove the suppressor and inspect the mounting points. Clean the mounting points, the suppressor, and the firearm before shooting again.However, when shooting a suppressed firearm, the velocity of the bullet will change, which will shift the point of impact. Therefore, when shooting a suppressed ZF-5, you will need to adjust the sights accordingly.

Calling a suppressor a silencer might be a bit of a misnomer because they don’t quite “silence” the gun, but they do make it shoot a lot quieter – as much as 35 dB, in fact.
Just be aware that you shouldn’t excessively lubricate the platform’s moving components for two reasons. One is that more oil attracts more fouling, and the other is that oil burns. The hotter temperatures associated with suppression can cause liquid lubricant to smoke, which can cause eye irritation and breathing difficulties.The Phillips head screwdriver can also be used to adjust the rear sight’s windage setting. To do so, locate the locking screw at the top of the rear sight and loosen it by about a quarter turn.

Before mounting, ensure that the firearm is unloaded and pointed in a safe direction. Inspect the silencer to ensure that it is clear and unobstructed.
Here’s what you need to know about shooting this subgun with a suppressor, as well as why it’s not just cool, but beneficial to the shooting experience. At the right side of the rear sight base, you should now be able to access the windage adjustment screw. Rotating clockwise shifts the windage adjustment to the left, rotating counterclockwise to the left. One full turn of the windage adjustment screw will shift the point of impact to the right or left approximately 2” at 25 yards. One thing that you will need to note is that suppressed firearms undergo substantially increased stresses during firing and also heat up more rapidly as a result of the captured gases. Firearms that are suppressed will also capture more fouling.To lower the elevation of the rear sight, rotate it clockwise; to raise it, turn counterclockwise. One full rotation of the rear sight drum’s elevation setting will shift the impact of the projectile approximately 2” at 25 yards. It’s also important to remember that the scale that uses dB is not linear, so a 1 dB reduction is quite substantial. To put it in layman’s terms, some suppressors can lower the volume of a gunshot about as effectively as a pair of earmuffs or headphones can. Utilizing the correct mounting interface (either the lugs or threads) attach the suppressor to the end of the barrel. Ensure that it is fully threaded on or securely locked before firing.

After you have finished firing, allow the firearm and suppressor to cool off adequately before attempting to remove it. Do not handle or attempt to remove the suppressor directly after firing as it can be hot enough to cause serious burns. Also, your ZF-5 will need more frequent (but still light) lubrication when shooting suppressed. We recommend keeping your American-made MP5 on the same lubrication and cleaning schedules. Make the necessary adjustments to your sights in the manner as described to rectify any shifts in accuracy that occurred as a result of suppressing the subgun.With that said, if your goal is recoil reduction, consider a muzzle brake instead. Whereas suppressors are heavily regulated and illegal in some states, muzzle brakes are not as controversial – not to mention they can cut recoil by as much as 50% without being as hard on the firearm’s internals.

Do Navy SEALs still use MP5?
The SEALs have employed the MP5 as a close quarters battle (CQB) weapon e. g. clearing a ship or a building. While the MP5 reamins in limited use in the teams, these days a SEAL is more likely to carry a short barrel rifle such as the MK18 CQBR 5.56mmx45mm carbine.
To adjust your American-made MP5’s rear sight you will need a Phillips head screwdriver and a spring cylinder tool. The spring cylinder tool contains spring-loaded tabs that can engage the rear sight drum’s detents, enabling adjustments to elevation.

Is HK MP5 suppressed?
Where other submachine guns have to use special subsonic ammunition for silenced use, the MP5 SD fires supersonic ammunition in the subsonic range (<340 m/s). It is also one of the most precise silenced submachine guns in its class.
Doubtless, a lot of shooters are attracted to suppressors because they have a lot of range “cool” factor. But the truth is, there is a lot of practicality associated with shooting a suppressed firearm. It’s not just about looks. SL4i-SMG MP5 have a robust construction and they are built for a long service life. Suppressor adds only 75 mm to the length of the weapon. SL4i-SMG MP5 suppressor is intended for users seeking the most compact suppressor solution, whilst still proving moderate sound suppression. SL4i-SMG MP5 is ultra-compact and lightweight 9 mm suppressors for the MP5 submachine gun. A 3-lug mounting system to attach the suppressors to the standard MP5 barrels. Sound suppression 13–16 dB (1 m left of the muzzle), 13–15 dB (shooters left or right ear).SL6i-SMG MP5 have a robust construction and they are built for a long service life. Suppressor adds only 75 mm to the length of the weapon. SL6i-SMG MP5 suppressor is intended for users who are seeking for more suppression level.

Can you put a silencer on a SMG?
So the short answer is yes, you can use a suppressor on a machine gun.
SL6i-SMG MP5 is ultra-compact and lightweight 9 mm suppressors for the MP5 submachine gun. A 3-lug mounting system to attach the suppressors to the standard MP5 barrels. Sound suppression 22–25 dB (1 m left of the muzzle), 16–22 dB (shooters left or right ear).

The HK® MP5 .22 LR Semi-Auto Rifle is developed as a civilian sporting rifle that matches the MP5 styling, in the convenient .22 LR plinking caliber for some fun time on the range. This model is equipped with a faux suppressor that also functions as a barrel shroud to cover up the 16.1″ barrel length required by the ATF. The left-side bolt release knob is reachable left or right handed and probably the most-famed object in the gun industry to slap. The fire control group features an ambidextrous safety selector and is made of a rugged polymer. On top of the rolled upper receiver, you’ll find the rear diopter sight allows you to switch quickly for different sight heights. The 16.1″ barrel hidden underneath the shroud is threaded for use of a real suppressor (not included). The paddle magazine release is proudly on the HK rifles entering the civilian world, which is a nice feature to see. A collapsible stock allows for compact concealment and rapid deployment.
The new RIA 5.0 Sporting Pistol from Rock Island Armory features a patented RVS Recoil system that maximizes barrel mass and linear movement to give shooters super soft recoil.Durability also receives a lot of emphasis from both SOCOM and Surefire. Modular suppressors are all the rage these days because they allow the shooter to tailor his can to the intended application. There’s usually a module that can be removed to make the suppressor shorter, and the mounting system is often threaded into the suppressor body. While these types of suppressors are lots of fun and are great for hobby applications, I’m skeptical of their place on the battlefield. The threaded sections of the suppressor body will never be as robust as a one-piece tube. If the suppressor encounters a partial bore obstruction or sees several magazines quickly fired through the rifle, there’s a better chance of spontaneous disassembly at the thread locations.

The negative impact backpressure has on a rifle, other than additional noise at the shooter’s ear, is the increased bolt velocity when the rifle cycles. This is why SOCOM placed a lot of emphasis on minimal backpressure. When the bolt speeds up, extraction and ejection have to happen in less time, so the odds of a malfunction increase (especially with worn parts in a rifle). Backpressure absolutely must be minimized for any suppressor that will see use on a semi­automatic or automatic rifle. If backpressure goes unchecked, reliability of the rifle will plummet.

Today, my personal AR-15 that I keep close at hand for self-defense is a Geissele Super Duty with a 14.5-inch barrel ( It also wears a fast-attach Surefire SOCOM556-MINI2 suppressor ($1,079). If the apocalypse started tomorrow, I would bet my life on this rifle and its suppressor.
The U.S. Special Operations Command (SOCOM) views suppressors as mission-essential equipment for reasons far more comprehensive than just making a gun quiet and eliminating muzzle blast. Suppressors have become increasingly important for our fighting men and women, so the demands placed on them are more stringent than ever before. Surefire won its first big SOCOM suppressor contract in 2011, and then won it again in 2017 because the company’s “cans” best met SOCOM’s needs. This article is a look at how and why that happened.
