On 6 May 2022, Ukrainian MP Oleksiy Honcharenko claimed that Admiral Makarov had been struck and badly damaged by a Ukrainian missile. On 7 May, the adviser to the Office of the President of Ukraine Oleksiy Arestovych said that the report was a “misunderstanding”, and that the vessel attacked was actually a Serna-class landing craft. On 9 May, Admiral Makarov was spotted sailing intact near Sevastopol.

On 29 October 2022, Admiral Makarov suffered damage during an attack on Sevastopol by several air and sea drones with at least one sea drone striking the ship during the attack, reportedly disabling the radar. Russian news agency TASS reported that all the air drones had been destroyed. Satellite footage from 1 November show Admiral Grigorovich-class frigates believed to include Admiral Makarov moored in Sevastopol. Naval News subsequently reported that little damage had occurred to either of the two warships that were hit by the sea drones, but that the military effect of the attack on the protected harbor of Sevastopol exceeded the direct damage because it led to the Russian Navy going into a protective mode, “essentially locking them in port. … New defenses were quickly added, new procedures imposed and there was much less activity. Russia’s most powerful warships in the war [were by mid-November] mostly tied up in port.”
On 18 August 2018, Admiral Makarov set sail from the Baltic Sea for the Black Sea and sailed through the English Channel on 21 August. She had been spotted while in transit there by HMS Queen Elizabeth in the English Channel on 18 August during her maiden voyage. After shadowing the British supercarrier, Admiral Makarov arrived at her permanent base in occupied Sevastopol in early October.

In 2022, Admiral Makarov—along with Admiral Essen—took part in the Russian invasion of Ukraine, targeting a Ukrainian oil refinery and fuel depots in the suburbs of Odesa with cruise missiles.
On 5 November 2018, the press service of the Russian Navy’s Black Sea Fleet announced the frigate had left Sevastopol to join the Russian naval group in the eastern Mediterranean.Admiral Makarov is an Admiral Grigorovich-class frigate of the Russian Navy, part of the Black Sea Fleet based at Sevastopol. She was laid down at the Yantar Shipyard in February 2012 and commissioned on 25 December 2017. She is the most recently built of her class, and the third of six ships that had been planned in the class as of November 2014.That said, the Canadian Firearms Program (CFP) has been working diligently to ensure that the FRT is updated to reflect all of the classification changes resulting from the Order in Council issued May 1st, which amended the Classification Regulations (the “OIC”).

What is the effective range of a Mk 12?

The Ottawa-based Royal Canadian Mounted Police had considered the Turkish 12-gauge semi-automatic shotgun “Non-Restricted” until June 15, when it suddenly revised its view.

Many firearm owners bought the Derya MK-12 after May 1 because it wasn’t named or covered by SOR/2020-96, and by its previous FRT entry. They consider the RCMP is overreaching its authority and prohibiting guns in secret via the FRT. The governing Liberal Party ordered mass rifle and shotgun confiscations on May 1, all the while saying repeatedly that owners of 10-gauge and 12-gauge shotguns are exempt. However, specific to your question, we do not maintain statistics on non-restricted firearms including the newly prohibited firearms previously classified as non-restricted.

This includes assessing variants or modified versions of the newly prohibited principal models which, the CFP’s technical experts’ may assess as meeting the new legal classification created by the OIC. The CFP is working as quickly as it can to ensure that these classification assessments are completed and that any changes be published in the FRT.
[Editor’s Note: Part 87 of SOR/2020-96, cabinet’s updated arbitrary list of blacklisted firearms, declares as “Prohibited” with some exceptions: “The firearms of the designs commonly known as the M16, AR-10 and AR-15 rifles and the M4 carbine, and any variants or modified versions of them…”] — The RCMP, which controls private firearm ownership in Canada, comments below on changing its legal opinion last month on the popular Derya Arms MK-12 shotgun to a “Prohibited variant” of the AR-15 or AR-10 rifle.
The FRT is an administrative document created by the RCMP’s firearms experts who have, based on the definitions set out in the Criminal Code and the types of firearms prescribed in the Regulations Prescribing Certain Firearms and Other Weapons, Components and Parts of Weapons, Accessories, Cartridge Magazines, Ammunition and Projectiles as Prohibited or Restricted (“Classification Regulations”) and the Firearms Act, conducted technical assessments of firearms to assist law enforcement officers, customs officers, and officials responsible for the regulation of firearms with the identification and classification of firearms.The FRT public version contains a link to a supplementary list that isolates those FRT records affected by the May 1, 2020, OIC. The records contained in the supplementary list are also in the FRT, and both are updated regularly.

The SPR has been used by US SOF in Iraq and Afghanistan and has been seen in use by the SEALS, Army Special Forces and the Rangers. The United States Marine Corps employ the Mk12 at the squad level, where it is used by designated marksmen.
The MK12 SPR is a modified variant of the M16 family of weapons. The SPR grew out of a requirement of the Navy SEALs and Army Special Forces for a compact light sniper weapon. To fulfill that need, the SPR is fitted with a threaded-muzzle match-grade free floating stainless steel heavy barrel. It fires the Mk 262 Open Tip Match Mod 1 round that has been specifically developed for the SPR. The SPR is a semi-automatic weapon that is fed from a 20 or 30-round STANAG magazine.The modular SPR is designed to be customizable to needs of the end user and as such can be configured with a range of butt stocks, optics and other accessories. The weapon’s hand guards are free-floating, a design, when coupled with the free-floating barrel, increases the weapon’s accuracy.

Is the Makarov BS 12 any good?
The Makarov S 12 is an impressive-looking shotgun. The one I tested came in the cool-looking black and dark green camouflage paint pattern. The gun is very good value for your money. You get a hard case with two, yes two 10-round magazines.
The Kel-Tec KSG-25 bullpup shotgun, however, flips conventional wisdom on its head, producing a shotgun that can store an astounding forty-one shots of ammunition internally. The KSG-25’s design makes it by far the largest capacity shotgun on the civilian market and aunique addition to a gun owner’s collection.Shotguns used for hunting or sport rarely suffer from the magazine capacity issue, but when it comes to defensive purposes more ammunition is always better. The KSG-25 can store an enormous amount of firepower for a single shotgun: up to twenty three-inch shells, 24 2.75 inch shells, or forty 1.62 inch mini-shells. The shotgun can also store one shell in the chamber, for a total of twenty-one, twenty-five, and forty-one shells, respectively.

Where are Derya shotguns made?
As Derya Arms, we are proud of the research and development, design and machine-based production in our factory, which has had a total enclosed area of 30.000 m2 in the Beysehir region since 1998.
A bullpup configuration weapon is one whose action is located behind the trigger group, often integrated directly into the buttstock. This maximizes the use of space lengthwise, resulting in a shorter weapon. Another benefit of placing the weapon’s action so far to the rear is the ability to have a longer barrel length. Bullpup weapons were previously the realm of assault rifles, examples of which are the U.K.’s SA80, Israeli Tavor, and the Austrian Steyr AUG.

Early bullpup assault rifles forced left-handed riflemen to shoot right handed, due to the facing of the ejection port to the right. Without modifying his shooting technique a left-handed soldier would get a face full of brass with each pull of the trigger. Kel-Tec’s shotgun, on the other hand, is lefty-friendly. The KSG-25 does not eject shells left or right but instead straight down. The shotgun also has an ambidextrous cross-bolt safety that blocks the action from firing.

Most fighting shotguns have a barrel length of eighteen to twenty-four inches. The KSG-25 however, thanks to its bullpup layout, has a barrel 30.5 inches long but an overall length of just 38 inches. By comparison the Mossberg 590 with an 18.5 inch barrel has an overall length of 39.5 inches. The KSG-25 does not actually need a 30.5 inch barrel–few if any shotguns are made with barrels this long–but since the twin feed magazines run underneath the barrel the long barrels mean added firepower. The longer barrel length also adds to the weapon’s muzzle velocity, but in shotguns there is less practical application than in rifles.

Two features allow the KSG-25 to pulls off this small miracle. The first is the use of two ammunition tubes instead of one, automatically doubling a shotgun’s typical ammunition reservoir. The second is the use of a bullpup configuration, which allows longer barrels and thus longer tubular magazines.Most shotguns have fairly small internal magazines. A conventionally laid out shotgun has a tubular magazine running parallel underneath the barrel that feeds a pump or semi-automatic operating system. The length of the barrel generally restricts the capacity of the magazine, with short barrel shotguns suffering the most. A Mossberg 590 shotgun with 18.5-inch barrel, for example, can only store seven twelve-gauge shells.

Kyle Mizokami is a defense and national security writer based in San Francisco who has appeared in the Diplomat, Foreign Policy, War is Boring and the Daily Beast. In 2009 he cofounded the defense and security blog Japan Security Watch. You can follow him on Twitter: @KyleMizokami.The KSG-25 shotgun is a fairly impressive engineering achievement. Manual shotgun technology for the most part plateaued decades ago, and it’s refreshing to see a new take on the pump action shotgun. While not for everyone, the KSG-25 provides unmatched levels of firepower.The KSG-25’s magazines feed separately into the shotgun, creating another useful feature: the ability to store different loads in the two magazines. The left magazine could be loaded with buckshot rounds, for example, and the right magazine filled with solid slugs. The flick of a magazine selector switch near the loading/ejection port allows the user to go back and forth between the two magazines as needed.

What shotgun do Navy SEALs use?
Navy SEALs use the Benelli M4 Super 90, Mossberg 590, and Remington 870 combat shotguns. The Benelli M4 Super 90, also known as the M1014 Joint Service Shotgun, is generally preferred. It was first delivered to the U.S. Marine Corps in 1999 after intense testing.
Originally the relatively expensive Parker-Hale swivel bipods were used, but were taken off the system after the initial SPR. Currently, a Harris swivel model bipod is typically used with the SPR, and is sometimes seen with a KMW Pod-Loc tension adjustment device. As mentioned above, the bipod is mounted via an ARMS #32 throwlever device attached to the bottom rail of the rifle’s forearm. The ARMS mount is used on both the MOD 0 and MOD 1.SPRs have been seen with M16A1 or M16A2 fixed buttstocks, telescoping M4 buttstocks, and the Crane Enhanced telescoping buttstock. The rifles are compatible with any type of stock system developed for the M16.An SPR, not a Mk 12 Mod 0. Note the early PRI freefloat tube of constant diameter. This SPR has a Versa-pod bipod and has a fixed stock. The upper receiver has a teardrop-shaped forward assist.In all cases a free-floating forearm is used, which does not touch the barrel directly. This increases the accuracy of the weapon by removing vibration and pressure exerted on the barrel by the rest of the gun. The first SPRs used PRI Gen I or Gen II carbon-fiber free-float tubes. The SPR/A, SPR/B, and MK 12 MOD 1 all use the Knights Armament Company M4 Match Free-Floating Rail Adapter System, KAC part number 99167.

US Army SF takes aim with his desert camouflage-painted SPR. An Insight Technologies AN/PEQ-2A Target Pointer/Illuminator Aiming Light (TIPAL) is mounted on the right of the rifle’s handguards. A standard M4 telescoping stock is mounted.
The SPR concept was originally proposed by Mark Westrom, president of ArmaLite, while working at Rock Island Arsenal in 2000. The program was an outgrowth of the desire by both US Army and Navy special operations forces for a rifle with greater effective range than an M4 carbine but shorter than an SR-25. The SPR program appears to have grown out of both the SOPMOD Block I program, and the U.S. Navy SEALs Recon Rifle, a 16″ flat-topped M16 carbine. Early models included the SPR, SPR/A, and SPR/B. The Naval Surface Warfare Center, Crane Division expanded on the Recon Rifle.

Is Derya a good shotgun?
The Derya Lion Practical is a very good shotgun. A more even trigger pull weight and a more durable finish would be a good thing.
This new bullet was found exclusively in an upgraded version of the Black Hills Ammo MK262 MOD 1 loading, but this bullet has been released by Sierra to reloaders prior to the end of 2014. The Sierra part number for this bullet is 7177.In 2014, Ops, Inc stopped manufacturing this model of suppressors. The equivalent product is currently manufactured by Allen Engineering Co as the AEM5. The AEM5 is essentially the same suppressor design and actually built by the same individual, Ron Allen, who previously fabricated the 12th model suppressor for Ops, Inc. Other models of this suppressor are also produced that look the same from the outside, but are fundamentally different suppressors. The OPS Inc. 12th Model SPR Muzzle Brake Suppressor threads directly onto the OPS Inc. muzzle brake and uses the collar to stay centered for Mk 12 MOD 0/1 models. The first 100 suppressors were made in RD Systems in South Beloit, Illinois. When the SPR program was still just an upper receiver assembly (and not a complete rifle), Crane assembled all of its prototypes using either M16A1 or M4A1 lower receivers, because the full auto trigger group in these lower receivers provided a consistent pull while the more common 3-round burst trigger groups didn’t.A long accessory rail, called a Swan Sleeve (ARMS SPR MOD or ARMS #38 SPR PEQ-2-3), manufactured by ARMS, is installed, running the length of the rifle. The SPR/A and SPR/B both used the KAC M4 Match FF RAS, KAC part number 99167. Two ARMS #22 Throwlever 30 mm steel rings are used to mount the dayscope. The SPR/A, SPR/B, and Mk 12 MOD 1 use ARMS #22 high rings, while due to the increased height from the SWAN Sleeve, the SPR and Mk 12 MOD 0/H use ARMS #22 medium rings. An under-the-handguard ARMS #32 Throwlever mount is used to mount the Harris bipod (the ARMS #42 Throwlever mount is used to mount the Versa-Pod); this features a quick release action. Nightforce Ultralite 1.375″ rings were also alternate issued rings, primarily with Nightforce riflescopes from Crane.

Is Makarov damaged?
Following the 14 April 2022 sinking of the cruiser Moskva, Admiral Makarov assumed the role of flagship of the Black Sea Fleet. On 6 May 2022, Ukrainian MP Oleksiy Honcharenko claimed that Admiral Makarov had been struck and badly damaged by a Ukrainian missile.
While a number of trigger options were tried in the end, the Knight’s Armament Company (KAC) 2-stage trigger was finally decided upon as the standard. Most of the obsolete M16A1 lower receivers were turned into NSWC Crane for disposal.The original SPR used an early PRI flip-up front sight with an elevation dial, which has since been discontinued. The Mk 12 MOD 0/H uses the current PRI flip-up front sight. The SPR/A, SPR/B, and Mk 12 MOD 1 use the KAC rail forend flip-up front sight, KAC part number 99051. The SPR and Mk 12 MOD 0/H use the ARMS #40 flip up rear sight. The rest of the models use the KAC 600 meter flip up rear, KAC part number 98474.The SPR was eventually type-classified by the U.S. Navy as the Mk 12. The weapon was developed by the Naval Surface Warfare Center Crane Division for US military special operations units.Black Hills then approached the Nosler bullet manufacturing company, who made a similar 77 gr (5.0 g) OTM bullet, and Nosler agreed to supply cannelured bullets to Black Hills.

Due to the relative modularity of the system, optics (as well as almost everything else) can be mounted according to the operator’s wishes. However, SPRs are most often seen with a 3.5–10×40 mm Leupold LR M3 (SPR/A), a 2.5–8×36 mm TS-30 (SPR/B), or a 3–9×36 mm TS-30 A2 (Mk 12 MOD 0/1) Mid Range/Tactical Illuminated Reticle Dayscope. Night vision devices can also be attached. These scopes usually come with flip open dust covers and a honeycomb anti-glare anti-reflection device. Given Nightforce Optics’ NAVSPECWAR contract, it is believed that many NAVSPECWAR issued SPRs will use the Nightforce 2.5-10×42 NXS scope.

An 18-inch (457 mm) (MOD 0/1) or 16-inch (406 mm) (MOD H) threaded-muzzle match-grade free floating stainless steel heavy barrel with a 1:7 (178 mm) rifling twist ratio is standard for the SPR.
The majority of the SPR upper receivers were initially supplied by Colt, with others being produced by Diemaco (now Colt Canada). Colt had been outsourcing parts of its production to Diemaco for several years, then purchased Diemaco in February 2005. It is unclear whether the upper receivers for the later SPRs came solely from ArmaLite, or were a mix of receivers from ArmaLite and Colt/Diemaco.

Is the Derya MK12 prohibited?
Based on a technical analysis conducted by firearms experts of the CFP, the Derya Model MK12, 12 GA, semi-automatic shotgun was assessed as a prohibited variant pursuant to item 87 of Part I of the Classification Regulations. Cached
The United States Navy Mk 12 MOD 0/1/H Special Purpose Rifle (SPR) is a designated marksman rifle that was in service with United States Special Operations Forces in the designated marksman role until 2017, also designed to be shorter than standard weapons. SPR initially stood for Special Purpose Receiver as it referred to an add-on upper receiver assembly (part of the proposed SOPMOD upgrades), but that nomenclature changed to Special Purpose Rifle as the weapon became a stand-alone weapons system. The newer load was designated Mk 262 MOD 1. Recently, Sierra added a minimal cannelure to its bullet, and this has since replaced the Nosler bullet in the current versions of Mk 262 MOD 1. In late 2014, Sierra introduced a tipped version of this bullet which adds a polymer tip to improve ballistics. The Mk 12 MOD 0/H uses PRI Gen III free-float tubes. The Gen I and Gen II Freefloat Forearms are combined with the Atlantic Research Marketing Systems #38 SPR MOD Sleeve, while the Gen III Freefloat Forearm, due to its it larger barrel nut, only works with the ARMS #38 SPR PEQ-2-3.

Early experience in influencing the SPR was from American forces deployed in Somalia when they used different optics, ammo, triggers, free float hand guards and rail systems for their rifles.
In mid-2011, SOCOM began removing the Mk 12 SPR from their inventory and replacing it with the marksman version of the SCAR Mk 17, with the Mk 12 being completely replaced by 2017.The SPR is not used to fire standard issue 5.56mm M855A1, M193 ball, or M856 tracer ammunition. Due to the limits in terminal performance and relatively poor accuracy of the 62-grain (4 g) M855 ball, the Mk 262 Open Tip Match (OTM) round was developed and manufactured by Black Hills Ammunition as a more accurate round for the SPR. The first production batches were designated Mk 262 MOD 0 and used a Sierra MatchKing 77-grain (5 g) Hollow Point Boat Tail bullet without a cannelure (crimping groove).

The barrels are manufactured by Douglas Barrels with a unique contour that reduced weight but maintained rigidity for accuracy. An OPS Inc. muzzle brake and collar (to align the OPS Inc. 12th Model Suppressor) is installed with the barrel.

What is the most damaging shotgun?
The KSG-25 can store an enormous amount of firepower for a single shotgun: up to twenty three-inch shells, 24 2.75 inch shells, or forty 1.62 inch mini-shells. The shotgun can also store one shell in the chamber, for a total of twenty-one, twenty-five, and forty-one shells, respectively.

Is Mk 12 a sniper?
The MK12 SPR is a modified variant of the M16 family of weapons. The SPR grew out of a requirement of the Navy SEALs and Army Special Forces for a compact light sniper weapon.
We create added value for the economy of our country with the quality management approach, careful work and cutting edge technology as our principles that our company will pass on to the next generations. Currently, not only local consumers but also the whole world are showing great interest in the high quality products that are manufactured in the Derya Arms factory.In today’s developing and evolving world, our talents and our biggest supporters, namely our dreams, are developing and changing as much as we do. As Derya Arms, we are proud of the research and development, design and machine-based production in our factory, which has had a total enclosed area of 30.000 m2 in the Beysehir region since 1998. It should be noted that our products, produced by encouraging our suppliers via bringing together world-class raw materials, equipment and qualified workforce, are exported after the most stringent quality control tests in our company and they successfully pass all kinds of quality and standardization tests of the countries they are sent to. In this way we market our high quality products worldwide and export 95 percent of our products to more than 65 countries.

BUFFERBOLT: Bufferbolt has also resulted from a long term rigorous and elaborate R&D study. Here, a stopper system comes into play in the mechanism. Thus, the mechanism maintains its functionality without damaging the case.
DAXOS: DAXOS is produced with 7075 aluminium materials and defined as the two-way cocking lever system of arms. Being a high level reflection of Derya Arm’s design capability, Daxos is an important example of the “Dual Use” concept.When people think of shotguns, they often have Italian products or small gunmakers in mind. However, more and more shotguns are coming out of Turkey in the form of semi-auto, pump-action and also break-barrel models. Often these are in the lower to mid price range and those who don’t want to or can’t spend a lot of money will find an inexpensive selection here. The Turkish manufacturer Derya, which is also active in the automotive sector, has been involved in gun manufacturing since 1998 and offers some shotguns with box magazines in the MK-12 model series. In Europe, the MK-12 IPSC is available in versions with a barrel length of 17”/43 centimeters, 19.6”/50 centimeters and 23.6”/60 centimeters. The fact that the design is based on the AR-15 is not only due to the spirit of the times, but also has practical reasons. The recoil is straight into the shoulder and the controls are located where they are on the AR-15. This is also a great advantage in action-packed 3-gun or multigun sports, for example, because you can operate the two different weapon systems, rifle and shotgun, identically. Thus, feeding by means of a box magazine, one can then act quickly in the usual manner without having to change over. This is how simple and practical the changeover to the shotgun can be.At the muzzle sits the mighty compensator, whose size and number baffles are due to the rather low gas pressure cartridges. An important feature of shotguns for sporting use is the adjustment of the shot pattenr by means of interchangeable chokes. Three choke sizes with cylinder, half and full choke are included with the gun. At least according to the instruction manual, our test gun probably had another cylinder choke instead of the half choke in the black plastic box, which is probably an isolated case. It is practical that Derya includes a long wrench with which the chrome-plated chokes can be changed without removing the compensator. However, if you want to disassemble the gun for cleaning, you have to remove the barrel and bolt to the front, even if the AR-15 design with the hinged upper and lower receiver might suggest otherwise. By the way, if you don’t want to use the compensator, Derya includes a long barrel sleeve that can be used to nicely disguise the muzzle area. Shotguns with box magazines seem to be more and more popular nowadays. The most sporty offshoot of the Turkish manufacturer Derya is available in a comprehensive set for around 1200 euros. But what can you expect in return? We tested it. Shotguns with box magazines based on the AR-15 or AK-47 semi-automatic rifle platforms exert a certain charm already in the overall appearance. Such guns have often been guests of – for example, we presented the Typhoon Defence F-12 or the Armsan RS-S1 with video. But they also have special features in terms of technology and handling. Reloading is much faster and easier than with semi-automatics with a tubular magazine located under the barrel. Even those who are not under time pressure often find this type of reloading more comfortable. Although it is possible to increase the reloading speed of semi-auto shotguns with tubular magazines by using special manual loading techniques or quick-loaders, those who are familiar with the magazine change from their rifle do not need to get used to it and, thanks to the design, it is quicker anyway. In addition, the many types of ammunition that can be fired from shotguns in the form of slugs, buckshot or birdshot can be changed more quickly if loaded reserve magazines are available. This is a circumstance that makes many shotguns with box magazines interesting for law enforcement. In the case of pump-action shotguns, such designs can be seen in the Mossberg 590 M or Remington 870 M, for example. However, anyone who wants to start in the IPSC field with the box magazine automatically enters the Open Division and thus the “Formula 1” of this dynamic, varied sport. Therefore, our protagonist is designed precisely for this international discipline, but could also be used for other purposes such as popper target shooting

18.8.2021 de aldığım sıfır mk12 tüfekle satıcının tavsiye ettiği mermileri kullanmama rağmen 2 mermiyi peş peşe atamadım 3 günlük tüfeği değişim yapılamıyor dediler. Aslında yapılabildiğini duymama rağmen ses çıkartmadım ama tüfekten soğudum eğer geldiğinde problem çözülmediyse direk tüketiciye gideceğim çözülürse de buradan bildireceğim. İnş genede ilk atışta yakışmadı. Tavsiye ediler bir marka ve tüfeğe tutukluk bu dereceNavy SEALs use the Benelli M4 Super 90, Mossberg 590, and Remington 870 combat shotguns. The Benelli M4 Super 90, also known as the M1014 Joint Service Shotgun, is generally preferred. It was first delivered to the U.S. Marine Corps in 1999 after intense testing. The M4 Super 90 is a gas-operated, semi-automatic, magazine-fed 12-gauge shotgun with an extended buttstock. It features an entirely new “auto-regulating gas operated” (ARGO) system that eliminates the need for complex mechanisms. The M4 Super 90 self-regulates for cartridges of varying lengths and power levels, firing 2.75 in. (70mm) and 3 in. (76mm) shells of differing power levels without any operator adjustments, and in any combination. This shotgun also has a Rail Integration System designed to attach scopes, laser illuminators, night vision sights, and flashlights.

The M4 Super 90 is built on a modular assembly basis, enabling it to be modified without any tools. This is especially useful in the field, in a changing tactical environment. This weapon is reliable and durable, and can operate for at least 2,500 rounds without having to replace any major parts. The M4 Super 90 (M1014) is planned for issue to all the U.S. military services. It replaces the Remington 870, Mossberg 590, and Winchester 1100/1200 tactical shotguns. The M4 Super 90 is durable, and reliable in all weather conditions.It was a bit like reuniting with a good acquaintance who got especially dressed up for this meeting. Tester Frank Flumm had tested one of the eye-catching red and black autoloading shotguns in the standard version in 2016. Back then, he was completely thrilled by the Derya Lion’s absolutely reliable function with virtually any type of ammunition and by its very good accuracy. In the meantime, a lot has changed at Derya.

The Lion Practical shows at first sight what kind of spirit it is. Not only the IPSC logo on the right side of the receiver indicates its intended use, but also the numerous technical and visual modifications compared to the old standard version. For example, the loading port on the underside of the receiver has been massively enlarged to facilitate double or quad loading. In addition, the controls such as the charging handle and the bolt release button have been significantly enlarged to prevent operating errors under competition stress. The synthetic stock with rubber inserts on the grip and fore-end has integrated recoil padding and ends in a non-slip rubber cap. The shotgun features a height-adjustable, ventilated barrel rib. The barrel rib also features a green fiber optic front sight and a rear sight with two red fiber optic inserts. In bright light, these sights provides excellent contrast and a very good target picture. In moderate lighting, however, the sights are less visible and aiming becomes much more difficult. Obviously, Derya specifically relies on these rib sights with the Lion Practical, because unlike the old standard version of the Lion, the top of the receiver does not have milling for 11-mm mounts, which makes it easy to fit a Picatinny or Weaver adapter rail. Now there are millings for a special mounting rail similar to Beretta, Fabarm or Winchester.
We took the Derya semi-automatic shotgun to the shooting range for an extensive test and tell you what the sporty Lion Practical model in 12/76 gauge did. All details about the gun and the test ratings can be found here.

Doch But how does this shotgun perform in practice? Immediately after unpacking, the magazine extension with the extended magazine spring was mounted. This was done without any problems and unlike some other shotguns, no helper had to be recruited to thread the magazine spring. The first range visit was unfortunately disappointing. The test gun was practically a pure single-shot gun with any ammunition. Apparently, the gas pressure was not sufficient to set the bolt fully in motion. The English instruction manual told us that when using light loads, one should remove the two gas pistons, turn them around, and reinstall them reversed. Unfortunately, that didn’t work in this case, because the barrel was too tight in the receiver for disassembly and the testers didn’t want to use force unnecessarily. No big problem: the shotgun was sent back to the importer for a check. After checking, the piston system was turned around for light loads. In addition, all functional parts were generously treated with GunCoating from Fluna Tec, a high-quality ceramic fine lubricant. The gun was then test-fired by the importer, and function was found to be good. And indeed: on the second attempt, the shotgun was unrecognizable on the shooting range. Now it cycled with all shotgun shells from 12/60 up to 12/76 magnum slugs without any problems. Even the very weak KO Cleanspeed Short posed no problem whatsoever, although with this load most other semi-automatic shotguns would have to pass. The 12/60 from Brenneke is really only for pump-actions. But that didn’t matter to Derya’s auto-loader: even with a deliberately loose grip, the shotgun now worked absolutely trouble-free with all cartridges used, including the 12/60 – chapeau!In 2023 a new or used Derya Arms MK-12 AS-155K AS-155K value varies depending on supply and demand. In the last 12 months there is great demand for a Derya Arms MK-12 AS-155K AS-155K and most shotguns. The Price for a Derya Arms MK-12 AS-155K AS-155K has increased in cost by $0.00 in 2023 compared to 2022.

Are Russian Makarovs good?
By the standards of the mid 20th Century, the Makarov was an excellent pistol. Even by today’s standards, it’s not a bad gun. They really are generally extremely reliable and I put a high priority on that for a self-defense gun. It’s just that, for the cost, you can do a whole lot better.
So, if you have a scope on top, when you get up close you can flip the gun on the side and access those irons too. They have Picatinny bases, so you could remove the sight and fit a red dot. But there’s more, an elasticated single-point sling, sight adjusting and fitting tools, cleaning cloth, Derya’s angled fore grip (AFG), combination tool with choke wrench, three, flush-fit chokes – Full, Modified and Cylinder. Plus, three magazines 2, 5 and 10-rounders, a set of ear plugs and a 2-year guarantee.However, filling these big magazines is always hard work when they are new, as you need a big spring to shift a column of 10 shells with a lot of thumb busting required to get them all in. Best is to fill them up and leave overnight to loosen things up. In testing, this was the only time I had stoppages, either with the first empty not fully ejecting due to the strong upwards pressure from the mag, or the second shell being pushed up too hard by the one below, which caused misfeeds. However, this symptom soon stopped, and I can say I had 100% reliability afterwards.

Jobs like this are for the bench when you have time and it’s easy to keep the gas system clean, not that it gets very dirty either! Overall, I liked the Mk-12, mainly due to its excellent reliability over a broad range of ammo and handling. The heavy controls are a niggle, but I can put up with them, suffice to say, if I were young again and shot PSG, I’d get one!
There are three radial, gas ports drilled at 45⁰ around the barrel, over this is a gas collar that is retained by a split washer in a cannelure. Inside this is the free-floating, top hat piston and behind, the operating tube with two extended lugs at the end. As the gun fires, gas enters the shroud and knocks the piston rearwards, which imparts a blow to the operating tube that moves back and hits the carrier, so initiating the unlocking movement. The carrier has a long rat tail that compresses the spring in the buffer tube, so storing energy for the return stroke. In use, over a wide range of ammo, from 28-gram # 7 and 8 loads through heavy AAA and OO buck shot and different slug types proved very reliable, with all ammo giving last round hold open energy.

Keeping abreast of the latest Practical/ Action shotguns is getting more problematic, due to their prolific nature of this near solely, Turkish-made and dominated sector. And although I have tested all four incarnations of the Akdal 1919, plus the Saiga 12, Molot Vipr and Hatsan Raider, I missed out on the UTAS 12 and Typhoon. So, I was pleased to get in touch with NDH Firearms (Dean Holgate) as he’s importing and distributing the latest Turkish Delight – the Derya Mk-12. From what I was told, Derya are the originators and inspiration for the M16-like UTAS and Typhoon guns. However, my research showed Derya’s earlier Mk-10, which is very much like the Akdal 1919 series, with its gas piston operating system. Plus, and though all M16-like designs the Mk-12, UTAS and Typhoon are a little different in terms of the operating system, with a simpler and more efficient mechanism.
Stripping was a bit confusing, as the Mk-12 opens like a real AR by pushing out the body pins, once the forend is off. I expected to be able to remove the bolt from the rear; not so! Forend and gas system off first, the combo tool has a C-spanner for the barrel nut, then pull back the gas collar, remove the split washer and then slide it off along with the piston and operating tube. Next, the barrel, which is retained by a castellated nut that screws into the front of the receiver. First, you must remove the locking Allen screw from underneath/between the forward hinge pin holes and with the tool use the other spanner end to remove collar and pull it clear. Then, pull out the cocking handle (very stiff), which frees the carrier/rat tail assembly from the bolt, which comes out forward with the carrier going either way.Last round hold open worked fine, but the manual bolt release catch, even with its big head button, proved very stiff to operate, I found it better to thump it with the heel of my hand. The mag button was similar, and the empty would not always fall free, however, this eased up after about 200-rounds. Felt recoil was acceptable with the shot loads and some CBC round ball slug, with control aided by fitting a vertical forward grip. The real test was some Winchester Supreme, Sabot, Partition Gold 385-grain, 2¾”, which was still nasty but not as much as in other guns. Also, heavy, was the trigger pull, at an overly firm 8 lbs, although it was useable once understood. The safety catch is a tad small and needs a bit more meat/length on the lever to get your finger on, I’d have preferred an ambi unit here! Slug accuracy was good with a Hawke 1-6×24 Frontier 30 with Tactical Dot AR reticle and bipod fitted, the CBC was printing 2-3” at 100m.

The gun arrived in a padded, plastic transit case with a lot of accessories. You get Magpul MBUS-type fold-down sights, D-Handle (combined AR15 rear sight and carry handle) and a pair of 45⁰ off-set irons.
Controls and features show a standard AR layout, with a small, single-sided safety catch on the left above the grip. The manual bolt release/hold open is on the left behind the mag well and shows a large/concave thumb rest. On the opposite side is the mag release button with a big head plate on the side of the mag well. The trigger guard is enlarged for easier access and two sling slots are fitted on the left; one at the buffer tube receiver junction and the other on the 9 O’clock rail. The bolt-mounted cocking handle is reversible, as there’s a corresponding slot on the left of the upper. It has a Buffer Bolt System (BBS), which is said to reduce felt recoil a bit, and consists of what looks like a hard rubber pad at the is the largest shooting resource and review based website, using the resources of Britain’s biggest and most comprehensive magazines – Gun Mart, Shooting Sports and What Gun. The Mk-12’s safety catch is live all the time; meaning that with the hammer un-cocked it still works. So, with the hammer down and the safety ON, you cannot cock the action; take note. The operating mechanism is a bit different from the standard, ‘connected’ gas piston system we are more familiar with. Now to the main event – the Mk-12. Though most Section 1 shotguns are a tad bulky, the Derya is less so, given its simpler operating system, as we shall see. Naturally, the butt is a telescopic CAR15/M4-type. Keeping it legal, minimum overall length is 41” with a 24” barrel, UK law says a shotgun must conform to the minimum dimensions of 40/24”. Like all of its ilk, it’s not small but feels handier than some.The build is substantial, with solid upper and lower receiver assemblies and a 12.75”, 4, way Picatinny forend; it’s not free-floating, as a nut that screws directly to the barrel keeps it on. This item is different looking to what Derya shows on its website, with a more waisted design and just front and rear Picatinny rail sections. The feel is not too aggressive, and you can always fit rail guards. The butt is a more basic L-shape, with a rubber recoil pad and heightadjustable comb. Length of pull (LOP) goes from 11.75 – 15” in four increments. The pistol grip is an A2 type (with single finger grove), but the lower receiver is deeper than normal, so might preclude the flush fitting of an alternative AR handle.

Rather than being slung underneath like the AKDAL or Hatsan Raider the operating mechanism is wrapped around the barrel and is of the short stroke tappet-type, as there’s no fixed connection to the bolt assembly. In this, it’s like the Browning Maxus, though here it’s underslung due to the fact this gun uses a
magazine tube. Unlike more conventional guns, the Mk-12 takes its gas from approximately 1/3rd of the way up the barrel, which means it’s at higher pressure, which should result in more reliable and versatile operation with varying power cartridges.
The Makarov is a double action/single action with a slide-mounted safety/decocker. But unlike the Walther — or almost any other pistol with a slide-mounted safety — you push it up to decock and go into safe mode. Down is fire. Usually it’s the other way around.

But that’s not to say all Makarovs were made in Russia. Bulgaria, East Germany, and China also produced the Makarov for their own military and police, as well as commercial copies for export. Since the fall of the Iron Curtain, plenty of Makarovs from all four countries have been imported for sale on the US civilian market. For the most part, there are only minor differences in the pistols based on country of origin. The East German Makarovs are generally considered the best in terms of fit and finish. This is a Bulgarian Makarov, which is probably the most common here in the States.

If you saw my video on the Walther PPK, you know I am not a fan of that gun at all. I do think the Makarov is a major improvement in a lot of ways. But it also suffers from some of the same drawbacks. It’s heavy. It has a lot of recoil for a small cartridge. And the biggest shortcoming is the sights. That’s the one thing that’s actually worse than the PPK. They’re very tiny, and obviously not designed with emergency use in mind, which is pretty typical of that era. Some of the commercial variants have fully adjustable target sights. But really, they’re not so great either, compared to a decent set of modern high-visibility sights.
You’ve been asking for it for years, so we finally reviewed the classic Makarov pistol. Is it just a Russian copy of the Walther PP, or did it play a more unique role in firearms history? We’re also taking a look at the ballistics of the 9×18 Makarov cartridge and how the Makarov stacks up as a carry gun option today.
