ABSTRACT:
An improved bolt construction for use in a paintball marker assembly is provided. The improved bolt assembly is generally formed to include a cut-out in the top surface thereof along its leading edge. The cut-out has a size and shape that functions in an manner that prevents the bolt from clipping or otherwise damaging a second incoming paintball projectile as the bolt reciprocates forward to ready a first paintball that is already loaded into the breech in preparation for launch. As the bolt is moved forward to push the first paintball into a position that is ready for launch, the leading edge of the cutout passes beneath the second paintball such that the top surface of the cutout impacts the bottom of the second paintball to push the second paintball upwardly as it advances, thereby clearing it from the breech and preventing the bolt from clipping the second paintball.
