ABSTRACT:
An automatic gun firing expendable breechcase ammunition having a receiver eciprocably mounted in a trunion-mounted, slide assembly and having the barrel fixed thereto to comprise the recoiling mass. Two pairs of trifurcated members are disposed within the receiver and rotatable on axes parallel to the firing axis for receiving ammunition from a clip feed mechanism, supporting each breechcase during firing and subsequently ejecting the empty breechcases. Cam mechanism interconnects the receiver and slide assembly and cycle the trifurcated members as the receiver moves in recoil and counterrecoil. A liquid spring system provides a substantially constant force to drive the receiver toward the maximum out-of-battery position and to oppose recoil and a laser system is provided to fire the gun as the receiver approaches the maximum out-of-battery position whereby forward momentum of the receiver overcomes part of the recoil force produced by the firing impulse.
