ABSTRACT:
A gas gun includes a pressure regulator assembly which controls the velocity of projectiles fired by the gun by adjusting the pressure within the gas chamber of the gun. The regulator assembly includes a spring-biased piston which is slidable within a gas seal between a source of pressurized gas and the gas chamber. The piston is movable between a first position in which gas can flow from the source of pressurized gas to the gas chamber and a second position in which gas is prevented from flowing from the source of pressurized gas to the gas chamber. The force exerted on the piston by the spring can be adjusted to control the gas pressure at which the piston moves to its second position.
