Abstract

There is disclosed a gas operated, fully automatic weapon system with a d feed mechanism having a long recoil, soft cycle operation. The automatic weapon system consists of six groups or sub-assemblies. These are the backplate (rear end cap/fire control assembly), the dust cover unit, the dual selective rotary feed unit, the operating group unit, the receiver unit, and the barrel unit. These sub-assemblies combine to provide a weapon characterized by lightness of weight, relatively slight recoil force, relatively slow gunfire rate, excellent manual control resulting in good burst fire accuracy in hitting targets, and safety during operation and disassembly.
