USAS-12 Combat Shotgun
The USAS-12 is a rare, full-auto 12-gauge combat shotgun developed in the late 1980s by Maxwell Atchisson and manufactured by Daewoo. Its classification as a 'destructive device' in the US significantly limited its market availability. The design features a long-stroke gas piston system, M16-style sights, and a unique long guide rod running through the gas piston.
