Kila Dirty Bolt™ patented series of aftermarket bolt systems enhance marker performance with an integrated inner thrust core that offers a dispersed operational sound signature. A soft inner core-tip cushion eliminates bolt-face-edge-to-paintball contact with no ball roll back. Inner core length is engineered to keep the ball stack centered between the soft cushion on the core and the ball-detents. This design feature assists to minimize cracking of the 2nd ball in the feed stack during the shooting sequence and reduces chances of barrel and breech breaks. Kila Dirty Bolt™ Series come standard with a color anodized aluminum magnetic ram locking pin and jewel. Other advanced design features include spooned air-scoop inlet on the inner core, designed to maximize flow rate around the 90° bend as airflow travels from the pop-it valve out the face of the bolt. The spooned air-scoop inlet size and pitch is timed for reducing recoil and optimizing shot to shot consistency over the chrono.
