ABSTRACT:
An ammunition feed mechanism for a machine gun includes a sprocket having rtridge feeding and positioning splines. This sprocket rotates in a feed direction to move a belt of linked cartridges into position for chambering and firing. An anti-backup pawl prevents counterrotation and maintains the sprocket in position while a cartridge is chambered. A ratchet release permits bidirectional rotation of the sprocket in loading and unloading of the ammunition belt. The rotation of the sprocket for feeding is done with a cam tube actuator making a ratchet connection with the sprocket. The reciprocating movement of the bolt carrier causes rotary movement of the actuator by means of a pin on the bolt carrier riding in the cam of the actuator. The bolt carrier has a depressible rammer for chambering the cartridges. This permits the bolt carrier to override a subsequently positioned cartridge during carrier recoil instead of the conventional recoiling of the carrier before subsequent moving of the next cartridge to its feed position.
