ABSTRACT:
A CO.sub.2 powered paint ball gun is provided operative to three times expand CO.sub.2 gas as it is extracted from a container of liquid CO.sub.2 and ducted to a position behind a paint ball disposed in the barrel of said gun. The gun includes three adjustments by which the velocity of the discharge of a paint ball from the barrel of the gun may be adjusted and includes a bolt action which is gas operated. Furthermore, the gun components may be readily disassembled for cleaning and/or repair and replacement and the initial expansion of CO.sub.2 gas under pressure occurs in a passage passing through the hand grip of the gun in a manner such that the chilled first expanded CO.sub.2 gas may be warmed by the heat of the user's hand grasping the hand grip.
