ABSTRACT:
A firing assembly of a paintball gun includes a piston, a spring, and a valve installed in a chamber in a frame of the paintball gun. The piston is a bar-like member having front member, a connection member, and a rear member. The connection member is smaller than the front member and the rear member to form a space thereunder. The valve is in the space to divide the space into a front room and a rear room. The spring urges the piston forward to have the rear member pressing an actuator of the valve that a high pressure gas will escape out of the valve to spurt out of the apertures via the rear room, the channels, and the front room. The high pressure also pressurizes the rear member to move the piston backward and compress the spring.
