Cost effective paintball gun system

A paintball gun system comprising:

• a bolt having a proximal end and a distal end and defining a firing passageway from a discharge inlet in the proximal end to a discharge outlet in the distal end;
• a body defining a receptacle for receiving the bolt, a firing charge storage chamber adjacent to but separate from the bolt receptacle, a gas inlet port, a first passageway between the storage chamber and the receptacle such that the storage chamber communicates with a first fluid opening into the receptacle, a second passageway between the gas inlet and the receptacle such that the gas inlet communicates with a second flow opening into the receptacle;
• wherein the bolt is axially movable within the receptacle between a chargeup position in which the bolt and the body together define a confined flow circuit between the first fluid opening and the storage chamber, and a firing position in which the bolt
• and the body together define a confined flow circuit between the storage chamber and the discharge inlet.
