Machine gun










Image Number 3 for United States Patent #6742434.

A machine gun incorporates an additional helical cam assembly to reduce asymmetrical loads imposed on the bolt head and bolt body. Bearing pads positioned on the bolt head serve to support the bolt head within the chamber area of the forward portion of the rotor to thereby improve the accuracy and consistency of firing pin strikes against the primer, resulting in improved cartridge detonation.
