  • Patent number: 6125735
    Abstract: A fully automatic self-loading weapon is disclosed. The weapon has a functional part that can be moved by the release of a round, and a connectable and disconnectable single-shot device which, when activated, causes release of one shot for every actuation of the weapon trigger. To restrict the number of rounds of a burst to only two rounds, after release of one round with the single-shot device disconnected, the movement of the functional part automatically activates the single-shot device so that only a single additional round is released.

  • Patent number: 6065384
    Abstract: The present invention relates to weapon systems that accelerate projectiles using gases generated by the rapid combustion of a solid propellant, in particular, such a weapon system is able to vary the barrel exiting velocity of the projectile through a barrel venting means. In one embodiment, a front venting means exhausts gas generated by combusting propellant from behind the accelerating projectile and redirects a portion of the exhausted gas either to at least one fixed volume, to the front of the projectile, or to a combination of at least one fixed volume and to the front of the projectile. Redirecting some of the exhausted gas to the front of the projectile restrains the projectile, thereby slowing the projectile, and thus further decreasing the muzzle velocity of the projectile. In another embodiment, gas from behind the projectile is exhausted into a fixed volume, thereby decreasing projectile acceleration, and thus, the muzzle velocity of the projectile.
