Originally developed in the 1980s, the USAS-12 takes many design cues from Maxwell Atchisson's 1970s vintage Atchisson Assault Shotgun, being a gas-operated magazine fed shotgun patterned after the M-16/AR-15 family of rifles, in particular arranging the firearm to put the barrel as close in line with the shoulder as possible to diminish felt recoil. Unlike the semi-automatic "destructive device" variation, this example is a true fully automatic military variation with a capability of 400-450 rounds per minute, designed to provide sustained firepower in a close-combat scenario, and is legally considered a machine gun by ATF standards. Elevation adjustable pin front and windage adjustable peep rear sights, with the former in a hooded post and the latter inside an integral carry handle, with a reversible cocking handle and ejector port cover, maker markings on the left of the receiver and the model, 12 gauge 2 3/4 inch chamber, and importer markings on the right. The handguard is ribbed and ventilated, with an AR-style trigger group and pistol grip and a fixed plastic buttstock with a ribbed rubber buttplate. Currently affixed with its included detachable 20-round drum magazine. Also includes its matching factory box, 6 extra curved box magazines, cleaning brush, plastic muzzle cap, and green/black nylon sling. This example is consecutively serial numbered to lot number 1584. Provenance: The Al Walker Collection
