ABSTRACT:
A paintball gun includes an air valve and a body portion, in which the body portion includes a paintball hole, a communicator, a piston, an axle and a bolt. By the pneumatic control of the air valve, the piston is pushed between the first and second positions, and the movement of the bolt is controlled between the third and fourth positions, so as to control the pneumatic air to flow out of the projection passage to project the paintball.
