ABSTRACT:
Paintball marker including a firing chamber having a barrel coupled to one end and a removable back plug coupled to an opposing end, a door surmounting a chamber loading hole disposed between back plug and barrel; a cam coupled to door; an actuator coupled to door cam; a pin valve interposed in a first gas path between a gas source and a passage leading to the chamber, and a trigger coupled to a second gas path between the gas source and actuator for opening the second gas path for actuating the actuator such that the door cam transforms motion of the actuator into pivoting motion of the door from an open position such that a paintball is loaded into the chamber to a closed position and then continuing to actuate the actuator to coact with the pin valve for opening the first gas path for firing the paintball.
