Airsoft gunsmith extraordinaire, Renegade Cow, demonstrates the realistic firing of the Northeast Airsoft Uzi GBB SMG after putting in cast zinc weight bolt inserts. The Northeast Airsoft Maschinenpistole MP2A1 is a highly detailed airsoft SMG modeled after the Uzi submachine gun. It boasts a realistic all-steel build, a strong gas blowback system for satisfying recoil, and an efficient gas nozzle design for improved accuracy, range, and velocity.
