ABSTRACT:
A bolt having an opening formed therethrough is slidably located in the bore of the gun. The bolt is held in a rear position by a sear with the bolt opening closed by a valve which extends into the bolt opening and engages a rear facing bolt seat. A passageway extends into the bolt opening for allowing pressurized gas to flow into the bolt opening. A trigger mechanism releases the bolt for allowing the bolt to be moved forward for allowing the valve and seat to separate for allowing the gas to flow through the bolt opening for forcing a ball from the rear end of the barrel out of the gun. The valve and bolt are constructed to allow initially a small amount of gas to flow through the gas outlet of the bolt and then to allow the full force of the gas to flow through the gas outlet. This causes the ball to start rolling before the full force of the air impacts the ball thereby minimizing breakage of the ball in the gun barrel.
