Automatic Shotgun
An automatic shotgun is an automatic firearm that fires shotgun shells (thereby making it a shotgun) and uses some of the energy of each shot to automatically cycle the action and load a new round. It will fire repeatedly until the trigger is released or ammunition runs out. Automatic shotguns have a very limited range, but provide tremendous firepower at close range. Design Automatic shotguns generally employ mechanisms very similar to other kinds of automatic weapons. There are several methods of operation, with the most common being gas, recoil, and blowback operated: * Gas operation uses the pressure of the gas (created by the burning propellant) behind the projectile to unlock the bolt assembly and then move it rearward. * Blowback operation uses the backward force applied by the projectile (due to Newton's Third Law of Motion) to retract the bolt assembly. * Recoil operation uses the backward force to retract the entire barrel and bolt assembly, which unlock at the re ...

Combat Shotgun
A combat shotgun is a shotgun issued by militaries for warfare. The earliest shotguns specifically designed for combat were the trench guns or trench shotguns issued in World War I. While limited in range, the multiple projectiles typically used in a shotgun shell provide increased hit probability unmatched by other small arms. History While the sporting shotgun traces its ancestry back to the fowling piece, which was a refinement of the smoothbore musket, the combat shotgun bears more kinship to the shorter blunderbuss. Invented in the 16th century by the Dutch, the blunderbuss was used through the 18th century in warfare by the British, Austrian, Spanish (like the Escopeteros Voluntarios de Cadiz, formed in 1804 or the Compañía de Escopeteros de las Salinas, among others) and Prussian regiments, as well as in the American colonies. As use of the blunderbuss declined, the United States military began loading smaller lead shot (buckshot) in combination with their lar ...

Armsel Striker
The Armsel Striker, also known as the Sentinel Arms Co Striker-12, Protecta, Protecta Bulldog and SWD Street Sweeper is a 12-gauge shotgun with a revolving cylinder that was designed for riot control and combat. History The Armsel Striker was designed by Hilton R. Walker, a Zimbabwean citizen, in 1981. Walker subsequently emigrated to South Africa, bringing with him the design for the Striker shotgun. His shotgun became a success and was exported to various parts of the world, despite some drawbacks. The rotary cylinder-type magazine was bulky, had a long reload time, and the basic action was not without certain flaws. Walker redesigned his weapon in 1989, removing the cylinder rotation mechanism, and adding an auto cartridge ejection system. The new shotgun was named the ''Protecta''. A copy of the Striker was made by the US gunmaker Cobray and marketed as the SWD Street Sweeper from 1989 through 1993. Design and features The weapon's action is similar to a revolver's, using ...

Vepr-12
The Vepr-12 is a multipurpose semi-automatic detachable-magazine shotgun, produced by Molot-Oruzhie Ltd. It is patterned after the original Kalashnikov rifle and built on the heavier RPK light machine gun receiver. History Early versions of the Vepr-12 were produced by Izhmash, with production moving to the Molot factory where the shotgun was redesigned and mass-produced. The Vepr-12 is intended to be a direct competitor to the widely popular Saiga-12 shotgun already produced by Izhmash. Like the Saiga, the Vepr-12 was designed to be a versatile weapons platform, capable of being used by hunters and professional shooters alike. With these considerations in mind, Molot introduced unique features, such as the ambidextrous safety selector, the bolt hold-open mechanism and a simplified magazine feeding mechanism. See . Features Due to the large difference in size between the 7.62×39mm cartridge and 12-gauge shells, the extractor port has been lengthened, allowing the shotgun to ej ...

Saiga-12
The Saiga-12 () is a shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named after the Saiga antelope native to Russia. Like the Kalashnikov rifle variants, it is a rotating bolt, long-stroke gas piston operated firearm that feeds from a box magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly. Saiga firearms are meant for civilian domestic sale in Russia, and export to international markets. The Saiga-12 is manufactured by the Kalashnikov Concern (the merger of Izhmash and Izhevsk), in Russia. Kalashnikov Concern also manufactures Saiga 20s and Saiga 410s in 20-gauge and .410 bore, as well as the Saiga semi-automatic hunting rifles in a number of centerfire calibers. Russian armed ...

Pancor Jackhammer
The Pancor Corporation Jackhammer is a 12-gauge, blow-forward gas-operated bullpup automatic shotgun designed in 1984 and patented in 1987. Only three working prototypes of the Jackhammer were built. Nonetheless, its distinctive aesthetics and futuristic design have made it a prop in action films, television programs, and video games. Development The Jackhammer was designed by John A. Anderson, who formed the company Pancor Industries in New Mexico. Anderson designed it based on his experiences using pump action shotguns in the Korean War and believed he could create a better shotgun, finding reloading pump action shotguns awkward and time consuming. Reportedly, several foreign governments expressed interest in the design and even ordered initial production units once ready for delivery. However, export of the design was held up for production due to United States Department of Defense testing, though the design was eventually rejected. Testing was done by HP White Labs in dest ...

Heckler & Koch HK CAWS
The Heckler & Koch HK CAWS (Close Assault Weapon System) is a prototype automatic shotgun—designed as a combat shotgun—co-produced by Heckler & Koch and Winchester/ Olin during the 1980s. It was Heckler & Koch's entry into the U.S military's Close Assault Weapon System program. It is a 10-round, 12-gauge, bullpup shotgun with two firing modes: semi-auto and full-auto. The gun is fully ambidextrous. Development The development of the HK CAWS started in response to the JSSAP requirement for Repeating Hand-held Improved Non-rifled Ordnance (RHINO),Hogg, Ian V. Jane's Infantry Weapons 1993-1994. Jane's Information Group. 1993 which itself grew out of the Special Operations Weapon (SOW) project. RHINO specified a magazine capacity of 10 rounds, a requirement for the new ammunition to be incompatible with commercial 12ga shotguns, that felt recoil to be no greater than a Remington 870P firing M162 or M257 buckshot cartridges and that the system provide penetration and incapacitat ...

Daewoo USAS-12
The USAS-12 (Universal Sporting Automatic Shotgun 12 gauge) is an automatic shotgun manufactured in South Korea by Daewoo Precision Industries since the 1980s. Design The USAS-12 is a gas-operated, selective fire weapon, designed to provide sustained firepower in close-combat scenarios. It accepts detachable 10-round box magazines or 20-round drum magazines. Both types of magazine are made of polymer, and drum magazines have their rear side made from translucent polymer for quick determination of the number of shot shells left. It has an effective range of 40 m. In the early 1990s, a new CQ model of the USAS-12 was created. It looks similar to the original model, but unlike the original, it lacks the front sight and has a re-modeled carry handle. The bolt locks on 1 cylindrical locking piece that moves up into round hole in barrel extension. History The history of the USAS-12 dates from the 1980s vintage designs of Maxwell Atchisson. In about 1989, Gilbert Equipment Co. (USA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atchisson AA-12
The AA-12 (Auto Assault-12), originally designed and known as the Atchisson Assault Shotgun, is an automatic combat shotgun developed in 1972 by Maxwell Atchisson (however, the original development by Atchisson seems to have produced only a few guns at prototype-level, with the development that ultimately lead to the gun entering the market being done later by Military Police Systems, Inc.). The most prominent feature is reduced recoil. The current 2005 version has been developed over 18 years since the patent was sold to Military Police Systems, Inc. The original design was the basis of several later weapons, including the USAS-12 combat shotgun. The shotgun fires in fully automatic mode only. However, the relatively low cyclic rate of fire of around 300 rounds per minute enables the shooter to fire semi-automatically de facto with brief trigger pulls. It is fed from either an 8-shell box magazine, or a 20- or 32-shell drum magazine. History In 1987, Max Atchisson sold the rights ...

AAI CAWS
The AAI CAWS (Close Assault Weapon System) is a prototype automatic shotgun—designed as a combat shotgun— produced by the AAI Corporation during the 1980s. It was AAI's entry into the U.S military's Close Assault Weapon System program. It is a 12-round, 12-gauge shotgun with two firing modes: semi-auto and full-auto. Development In 1982, the United States was seeking entrants for their Close Assault Weapon System program. Grown out of previous combat shotgun programs, this program had inherited the specification from the RHINO program that had preceded it. These specifications required a magazine capacity of 10 rounds, a requirement for the new ammunition to be incompatible with commercial 12ga shotguns, that felt recoil be no greater than a Remington 870P firing M162 or M257 buckshot cartridges and that the system provide penetration and incapacitation capability significantly better than M162 and M257. In response to this, AAI developed their entrant, the AAI CAWS - a sel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
