    摘要： The machine gun of this invention features a unitary bolt and bolt drive assembly reciprocably mounted within a receiver along three longitudinally extending bearing supports symmetrically arranged in spaced relation to the receiver; the bolt and bolt drive assembly, together with a recoil buffer constituting an integral operating group removably maintained within the receiver by a single latch mechanism; a bolt carrier of the assembly incorporating actuating means for cartridge belt advance, cartridge extraction and ejection; the bolt carrier housing not only a rotary, front-locking bolt but also a cam follower which fixes a firing pin to the carrier and moves within a contoured slot in the bolt for locking and unlocking it in battery. This machine gun also features a gas recoil system for the bolt and bolt drive assembly having anti-fouling porting means for purging gas from the system under high pressure after firing; an ejector operated by the recoiling bolt and bolt drive assembly independently of its velocity; an automatically engageable, selfaligning barrel and receiver latch construction; and a sight assembly featuring a zero backlash precision screw adjustment means.

    摘要： A system for feeding and firing ammunition of the variety having no casing. Sealing of the firing chamber is accomplished by providing a reciprocating bolt assembly having a bolt projection which is telescopingly received in the barrel bore. The projection picks up and seats the projectile in the firing chamber. The propellant charge may be secured to the projectile, or may be separately loaded in the bolt mechanism. In the latter case, a fluid passage extends from the propellant chamber through the bolt projection to the projectile chamber.
