The Masterkey is a door breaching shotgun system manufactured by Knight's Armament Company. The Masterkey project was initiated during the 1980s to provide assault rifles with a potent built-in door breaching tool. Individual soldiers were often forced to carry a breaching shotgun in addition to their standard-issue rifle, but the Masterkey ...
A US Marine practices shotgun door-breaching techniques. A breaching round or slug-shot is a shotgun shell specially made for door breaching.It is typically fired at a range of 6 inches (15 cm) or less, aimed at the hinges or the area between the doorknob and lock and doorjamb, and is designed to destroy the object it hits and then disperse into a relatively harmless powder.
Military Armament Corporation (MAC) was an American manufacturer of small arms, co-founded by Gordon Ingram, an engineer and gun designer, and Mitchell WerBell, owner of SIONICS, which manufactured gun sound suppressors. It is known for manufacturing the MAC-10 and MAC-11 machine pistols in the 1970s.

The M4 was the first gas-operated shotgun produced by Benelli. Its function is designed around an entirely new design called the "auto-regulating gas-operated" (ARGO) system.
Failure to feed (FTF) is when a firearm fails to feed the next round into the firing chamber. Failure to feed is common when the shooter does not hold the firearm firmly (known as limp wristing), when the slide is not fully cycled by the preceding round, or due to problems with the magazine. It can also be caused by worn recoil springs, buffer ...
The problem is particularly pronounced when armour-piercing fin-stabilized discarding-sabot (APFSDS), a type of long-rod penetrator (LRP) (or kinetic energy penetrator), are used. [23] Since these APFSDS rounds are the most common armour-piercing ammunition currently, virtually no modern main battle tank guns have muzzle brakes.
The M26-MASS was chosen by the U.S. Military over the Masterkey as a breaching tool. [4] Small numbers of M26-MASS shotguns were issued to U.S. troops in Afghanistan. The current contract calls for the delivery of 9,000 shotguns. [2] In February 2012, the first unit was fully equipped with M26-MASS. [5]
The term originates from artillery, referring to a gun that fires before it has been pulled back. In artillery guns, "out of battery" usually refers to a situation where the recoiling mass (breech and barrel) has not returned to its proper position after firing because of a failure in the recoil mechanism. Most gun carriage designs should prevent this; however, if a g
