Abstract: A pneumatic paintball marker has, for example, a bolt assembly with a boost feature. The bolt assembly has multiple air supply chambers which apply force to move the bolt towards the firing position. Preferably, the air supply chambers push the bolt in series. The marker includes a handgrip frame that has a rear portion that flows into the base of the body. The material of the rear portion preferably is a rubber. The bolt assembly includes a set screw so as to prevent the bolt assembly from rotating within the body. A pin depth of the airport component is user adjustable.

Abstract: An anti-chop system for a pneumatic paintball marker that is automatically cleaned. The anti-chop eye system includes a transmitter and receiver arranged so as to sense the presence of a paintball within a breech using a beam of light. A moving member of the paintball marker automatically wipes at least one surface of the transmitter and/or receiver to remove contaminants such as paint, grease, dirt and the like. By automatically cleaning the anti-chop eye system, the reliability of the system is improved.

Abstract: The present invention contemplates a novel and unique pneumatic paintball marker with a variety of novel features the first being an on/off compressed air control valve at the front of the marker below the barrel adjacent to the inline pressure regulator. Major innovations have been made in reducing the size and weight of the body of the marker along with the construction of the new fuse bolt assembly consisting of just four components and only one moving part. An anti-chop eye electronic system insures the paintballs are in the proper position with the addition of rubber ball detents to hold the paintballs in place so that they will not roll out the barrel prior to firing the marker.
