    Abstract: A Picatinny mounted, left side charging handle system adapted for mounting on AR-15, M-4, or M-16 and similar rifles. The charging handle mounts on the foremost Picatinny mount of the upper receiver and replaces OEM charging handles provided with the rifle. Side mounting overcomes the problem of a shooter's finger being moved from the trigger and/or the shooter's cheek moving from the stock weld so that the shooter's eyes may remain on the intended target. The novel charging handle mounts on the upper receiver and readily accommodates mounting virtually any optical device in addition to the charging handle. The novel charging handle may be mounted to the rifle with no rifle modification required. Rifles may alternately be charged by pulling back a protruding rear portion of the charging handle. The apparatus may readily be transferred between rifles. The rifle equipped with novel charging handle remains fully field strippable without tools.

  • Patent number: 8297167
    Abstract: A reciprocally-cycled, externally-powered weapon may include a rotative driver connected via a crank and connecting rod to the operating group of the weapon. The connecting rod may be connected to a pinion that meshes with a translating rack and a stationary rack. The translating rack may be connected to the operating group, and the stationary rack may be fixed to the receiver of the weapon. The energy needed to fire the weapon may be supplied by an energy generator. The minimum amount of energy supplied by the energy generator may be independent of the speed of translation of the operating group and may be sufficient to reliably result in cartridge ignition, thereby providing an infinitely adjustable firing rate.

  • Patent number: 8297164
    Abstract: A remotely operable machine gun charger is provided for selectively controlling the forward-to-rear movement of a machine gun bolt pin. When the bolt pin is released from its safe position the charger permits the bolt pin to be spring-driven back to its armed position substantially instantaneously by the bolt spring without waiting for pin engagement and drive structure portions of the gun to be returned to their forwardmost positions. The charger permits the gun to be fired during such movement of the engagement and drive structure back to their forwardmost positions, and the charger may be mounted on and removed from the machine gun without the use of tools, or the necessity of removing or adjusting any of the internal components of the machine gun.
