Captain Mack Gwinn, a retired U.S. Army Special Forces officer, founded Gwinn Firearms Company in 1972 and introduced a unique rifle and pistol. The company was later purchased and rebranded by Quality Parts as Bushmaster Firearms, which became a significant player in the U.S. firearm market. The Bushmaster Arm Pistol, one of the company’s notable designs, was intended to be fired from the hip and has features borrowed from both the AR-15 and AK-47. Despite its limitations in practicality and accuracy, the pistol has earned its place as a unique piece of firearm history.
