ABSTRACT:
The present invention features an improved paint-ball pistol, which has two detent-pin mechanisms, one of which firmly affixes the front receiver of the gun to the trigger housing, and one of which that firmly affixes the barrel to the front receiver. In the event that either the front receiver must be detached from the trigger housing or the barrel from the front receiver (as in those instances when a paint-ball capsule ruptures therein), the detent-pin mechanism allows for immediate and almost instantaneous removal thereof. The detent-pin mechanisms each have a knob that is movable between a locked and a retracted position, and a screw that is affixed to the knob. The screws extend from the knobs through the front of the trigger housing and through the forward portion of the front receiver. The ends of the screws extend beyond the inner trigger housing surface and beyond the inner front receiver surface and into the holes in the outer surfaces of the front receiver and the barrel of the gun. About each of the screws is a coil spring, which is captured at a top portion of the screw by a jam nut. The outward, pulling movement of the knob removes the screw shaft from the hole in either the front receiver or the barrel. In this retracted position, the front receiver or the barrel is freed from its original position, and can be slidably removed. The operator then has both hands free to disengage either piece. The part can then be slid back, and the knob quarter-twisted and returned to its initial, locked position. The detent-pin mechanism of this invention makes the removal of both front receiver and barrel and their reinsertion a quick procedure, one that is achieved by a simple pull and twist of a knob.
