Abstract
An automatic weapon firing mechanism consisting of a slideably movable bolt arrier with cam slots cooperating with pins on the bolt and firing pin for rotating the bolt to lock it in battery position for firing and to cock the firing pin during recoil. Continued forward movement of the carrier after the bolt is locked causes the firing pin to sear off and strike the chambered cartridge. The firing pin has its own firing spring so that a constant reliable striking force is applied to the cartridge. Gas from the spent cartridge recoils the bolt carrier, unlocking the bolt and cocking the firing pin during recoil.
