M1014 and M1015 Automatic Shotguns
The US military has used pump-action shotguns as far back as the Philippine Insurrection, when the Winchester Model 1897 was used to good effect against the Moros. As time progressed however, the military has always longed for an accurate, reliable, and rugged semiautomatic shotgun for use. The US military made do with the Mossberg M-590 pump-action design for almost a decade before the announcement was made of a new adoption. Tests were held starting in 1990 by the US Marines for a combat shotgun; the first tests were held in 1996 in which the Benelli M-4 Super 90 was judged to be superior to existing models in use. However, while Benelli did not have any large presence in the US military establishment at the time, Benelli licensed the design to Heckler & Koch for sales in the US, and the US military type-standardized the new shotgun as the M-1014. Elsewhere (including among US police forces and civilians), the design is sold through Benelli and is known as the M-4 Super 90. Testing by the US military began in 1999, with first fielding in 2001.
The M-1014 is a semiautomatic, gas-operated shotgun; during the testing of the weapon during trials it fired over 25,000 rounds of ammunition without having to replace any major parts in the process. The operating system is self-regulating, without the need for adjustment for special ammunition (though some must be hand-loaded directly into the chamber), and different-length shells can actually be loaded into the M-1014’s tubular magazine at the same time. The operating system also allows changes to the barrel length with only minimal adjustments. (Standard barrel lengths for the US military are 18.5 and 14 inches, but Benelli says other barrel lengths are quite possible.)
The M-1014 makes use of a special telescoping stock arrangement that allows the user to use the stock retracted for close-quarters battle if needed; however, the M-1014 may also use two other stocks – a fixed stock with a pistol grip, and a fixed stock with a conventional layout. Each stock has a recoil pad. The stocks are interchangeable without tools, but the collapsible stock is standard for the US military. The receiver of the weapon is made with a MIL-STD-1913 rail on top so that the weapon can mount optical sights or laser aiming modules on top of the receiver rather than on the tubular magazine. The tubular underbarrel magazine includes a speedloader to enable quick reloading.

The Auto Assault-12 (AA-12), originally designed and known as the Atchisson Assault Shotgun, is a shotgun developed in 1972 by Maxwell Atchisson. The current 2020 version, first deployed in 2005 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 weapon is selective fire, operating as a semi-automatic, or in fully automatic mode at 300 rounds per minute. It is fed from either an 8-shell box magazine, or a 20- or 32-shell drum magazine.
In 1987, Max Atchisson sold the rights of AA-12 to Jerry Baber of Military Police Systems, Inc., Piney Flats, Tennessee. MPS in turn developed the successor simply known as Auto Assault-12, which was redesigned over a period of 18 years with 188 changes and improvements to the original blueprint. MPS also teamed up with Action Manufacturing Company, and Special Cartridge Company to combine the gun with FRAG-12 High-Explosive ammunition into a multifunction weapon system.
The weapon was lightened to 4.76 kg (10.5 lb) and shortened to 966 mm (38.0 in) but retained the same barrel length. The CQB model has a 13-inch barrel, and is half a pound lighter than the regular model. Uncommon in other automatic shotguns, the AA-12 fires from an open bolt, a feature more commonly found in submachine guns and heavy and squad level machine guns. It uses 8-round box, 20-round drum, or 32-round drum magazines, as opposed to the original 5-round box magazine. Due to the abundant use of stainless steel and the designed clearance for fouling, MPS has claimed that the weapon requires little to no cleaning or lubrication. The designer states that cleaning is required after 10,000 rounds.
The AA-12 can use different types of 3" 12 gauge ammunition such as buckshot, slugs, or less-than-lethal rubber stun batons. Like most 12 gauge shotguns it can also fire flares or special Frag-12 19 mm fin-stabilized HE, HEAP, and sensor fused HEAB “air-burst” fragmentation shells that can detonate in mid-air.
