ABSTRACT:
An automatic firearm of especially simple construction and easy maintainability, having an adjustable cyclic firing rate. The firearm has a receiver with an upper and lower portion. The upper portion defines a cavity in which a bolt assembly reciprocates. The reciprocation is maintained by a single compression spring in the cavity, and the length of the cavity, and compression of the spring, are adjustable to vary the cyclic firing rate. The firearm includes an especially simple trigger group arrangement. The lower receiver portion is structured to protect the trigger group. Also disclosed is an especially simple, yet practical ejector mechanism.
