Bushmaster Semi Automatic Pistol
This semi-auto pistol features a parkerized finish and a rifle-style box magazine in a bull-pup configuration. This firearm was manufactured by Gwinn Arms during 1972-1974. The design blended aspects of the AR-15 and AK-47 rifles into a bullpup pistol configuration. The pistol was considered for a USAF survival arm and also by the California Highway Patrol.
