AbstractWhat 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 guide tube attached to the hammer. The guide tube extends into a bore within the bolt and is dimensioned in close tolerance to the bore within the bolt. The guide tube thereby is capable of sliding smoothly within the bore of the bolt to provide support for the hammer as it is propelled rearwardly during the firing operation.
