TheBushmaster Arm Pistol was a5.56×45mm NATO firearm, categorizeable as either a long pistol (under the American legal definition of a pistol) or compact carbine rifle, produced by the Gwinn Firearms Company, and laterBushmaster Firearms Inc. The firearm was a new design, having a rotating bolt combined with a long stroke gas piston system similar to theAK-47 rifle.[2][3]
SomeAR-15 parts were used in its construction and it used STANAG type magazines.[4]
Production ceased in 1988 for the pistol variant and 1991 for the rifle following Bushmaster's acquisition by the Quality Products Company the previous year;[4] the company now known as Bushmaster is primarily known for making the more commonAR-15 type rifles.[5][4]
