Abstract
A paintball gun is sized and designed to appear like and operate in a manner similar to a conventional gun. A dual-action firing bolt moves forward, assisting in launching a projectile, under cast pressure. The bolt then releases the compressed gas to carry the projectile down the barrel. Return springs operate to move the bolt and its valves to a ready-to-fire position. Similarly, trigger actuation mechanisms are spring-actuated to return to the ready-to-fire position. A removable magazine stores projectiles and propellant. The magazine is small enough to fit into a handle of a pistol. A user may selectively release just the projectile portion of the magazine, in order to leave the propellant undisturbed until fully expended. The magazine can be completely removed without substantial loss of propellant.
