This disclosure relates to machine guns. Its features include: two feeding means mounted in tandem in a feed tray slideably mounted on the gun receiver for selectively feeding cartridges from two separate cartridge belts; receiver operating slide inertia control comprising energy absorption means responsive to the rate of movement of the operating slide effective to compensate for different cartridge propellant characteristics by absorbing increasing amounts of slide energy at increasing slide speeds; quick release mounting for the receiver and barrel including a retaining element, a receiver element removably supported in the retaining element and a barrel element removably supported both in the receiver element and the retaining element; a removable receiver back plate with locking means effective to prevent removal of the back plate when the operating slide springs are dangerously compressed in cocked position; an accelerator in contact with both the barrel actuator and the operating slide for immediate operation of the slide upon firing; a cable secured to the operating slide provided with a handle for cocking the operating slide; and a novel buffer for cushioning the movement of the barrel into firing position.
