The Saiga-12 is a 12-gauge shotgun available in a wide range of configurations, visually patterned after the Kalashnikov series of assault rifles. Like the Kalashnikov rifle variants, it is a rotating bolt, gas-operated
gun 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.

The ancestor to the modern minigun was made in the 1860s. Richard Jordan Gatling replaced the hand cranked mechanism of a rifle-caliber Gatling gun with an electric motor,
a relatively new invention at the time. Even after Gatling slowed down
the mechanism, the new electric-powered Gatling gun had a theoretical
rate of fire of 3,000 rounds per minute, roughly three times the rate of
a typical modern, single-barreled machine gun. Gatling's
electric-powered design received U.S. Patent #502,185 on July 25, 1893.[1]
Despite Gatling's improvements, the Gatling gun fell into disuse after
cheaper, lighter-weight, recoil and gas operated machine guns were
invented.

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 XM25 CDTE fires 25mm Grenade that are set to explode in mid-air at or near the target. A laser rangefinder in the weapon is used to determine the distance to the target. The user can manually adjust the detonating distance by up to 10 feet (3.0 m) shorter or longer; the XM25 automatically transmits the detonating distance to the grenade in the firing chamber. The grenade tracks the distance it has traveled by the number of spiral rotations after it is fired, then detonates at the proper distance to produce an air burst effect. These features make the XM25 more effective than traditional grenade launchers at the task of hitting targets that are behind cover or dug into the ground (i.e. in defilade.) One of the weapon's developers, Richard Audette, believes that the XM25 is a big leap forward because it is the first small arms weapon to use smart technology.
