Abstract: A compressed gas powered gun having a valve assembly (40) for regulating the pressure from shot to shot, a trigger assembly (36) which alters the mode of operation of the gun and a bolt (38) for providing a recoil action and for releasing the gas from the valve assembly (40). The valve assembly (40) provides sufficient pressure to expel a projectile and to re-set the bolt (38) into its firing position. The trigger assembly is formed from a trigger (26), a four-position selector switch (46), and a sear (74). The gun uses an operation rod (118), which is integrally connected to the bolt (38) to advance the gun's magazine.

Abstract: A firearms training simulator provides recoil simulating the recoil of a conventional firearm. The valve assembly provides consistent rearward gas pressure for generating recoil. Preferred embodiments of the firearms training simulator may include a means for adjusting the amount of recoil provided. A trigger mechanism permitting semi-automatic operation, or full automatic operation at a user selectable cyclic rate, is provided. The firearms training simulator further provides a laser emitter structured to emit a laser substantially along the same path as a bullet fired from a conventional firearm having the same configuration as the simulator.

Abstract: A compressed gas powered gun provides recoil simulating the recoil of a gun firing gunpowder propelled projectiles. The valve assembly provides both consistent shot to shot pressure, and rearward gas pressure for generating recoil. Preferred embodiments of the compressed gas powered gun may include a mechanism for adjusting the amount of recoil provided. A trigger mechanism permitting semi-automatic operation, or full automatic operation at a user selectable cyclic rate, is provided. The air gun provides consistent gas pressure behind the projectile from shot to shot. A magazine and magazine indexing system for loading projectiles into the firing chamber in a manner contributing to the accuracy of the air gun is also provided.
