ABSTRACT:
A rifle mechanism that will automatically fire, from a single barrel, a te-round burst at approximately 4,900 shots per minute (spm) without the use of a round counter, is disclosed. The rifle mechanism includes a cam and follower mechanism. The cam path controls the basic function of the rifle system to obtain the highest rate of fire with minimum operating rod velocities and to provide the ability to fire the three-round bursts without a round counter. The three rounds are loaded simultaneously into a chamber and the chamber is indexed to fire out each round before extraction. This eliminates the need for a full stroke cartridge handling mechanism.
