The Classic Army M132 gives you the firepower of an army in a small and compact form!  It features 4 gatling style rotating barrels and fires up to 550 feet per second at up to 25 rounds per second.  This gun uses HPA (High-Pressured Air) to blast out BBs and a 12V battery to rotate the barrels, so you can adjust the pressure per square inch to change the velocity of the BBs coming out.  It has an internal BB storage tank that holds 2000 BBs. Note: HPA tank and rig required (not included). Please use a minimum battery voltage of 11.1v (12V recommended).
