Developed in 1985, the Colt SMG was targeted at the American law enforcement market as a domestic alternative to the Israeli Uzi or German MP5, using Colt's own AR-15 rifle as a base. The result is a straight blowback pistol caliber automatic carbine with near identical controls and operation to the AR. Post front and two-leaf rear sights, with a birdcage flash hider and bayonet lug on the shortened barrel, a pinned-in two-piece adaptor block in the magazine well, right handed "SAFE SEMI AUTO" selector switch and an A1 pattern upper with no forward assist and an extended plastic case deflector. With a checkered pistol grip stock and a two-position telescoping buttstock. Magazine not included.
