Abstract
What is provided is an improved gas-powered gun for projecting lightweight projectiles, such as paint balls. Like guns presently available on the market, the gun of the invention has a handle, a barrel, a projectile chamber within the barrel, a bolt disposed within the barrel immediately rearward of the projectile chamber, a hammer disposed immediately rearward of the bolt, a spring for propelling the hammer rearwardly during the firing operation, a pressure chamber which retains a discreet amount of a pressurized gas and a valve for releasing the pressurized gas to the projectile chamber upon impact from the hammer. The improved gun of the invention differs from the gun presently on the market by the fact that the improved gun has a cocking mechanism comprising a pump handle slidably disposed around the barrel, and a bolt link slidably disposed in a longitudinal groove defined within the exterior surface of the barrel parallel with the longitudinal axis of the barrel. The bolt link is attached to the pump handle at its one end and to the bolt at its other end.
