Abstract:
1. A pneumatic paintball marker configured to fire a paintball, said pneumatic paintball marker comprising: a body member having a longitudinal bore; a trigger connected to said body member and configured to move between a firing position and a non-firing position; a barrel extending from said body member and in flow communication with said longitudinal bore, said barrel having a breech; a bolt assembly housed in said bore and having a cap and a bolt, said bolt being configured to translate longitudinally within said cap; a sail extending radially from said bolt and being configured to hinder gas flow between said bolt and said cap; an anti-chop eye electronic system having at least a transmitter eye and a receiver eye, wherein said anti-chop eye electronic system prevents said paintball marker from translating said bolt and firing said paintball when said paintball is not positioned in said breech; and a circuit storing software for controlling translation of said bolt, said circuit receiving a signal from said anti-chop eye electronic system after said paintball is fired and before another paintball is positioned within said breech to determine whether said transmitter eye or said receiver eye is dirty.
