By utilizing the latest technology in High Speed Video Imaging we have been able to further refine the already outstanding Cure2 Bolt for the Eclipse Ego. The Cure3 allows for perfect positioning of the ball in the breech for every shot, and the new upper ramp profile offers 2 distinct improvements over its predecessor. The first is that is further reduces the impact of the second ball in the feed stack and the subsequent compression of all the balls in the stack above it. And secondly, it allows faster load times as the stack is already partially lowered into the breech as the bolt starts to retract meaning a shorter drop distance and time during the loading phase of the cycle. The Cure3 Bolt will fit all previous Egos, but will require the fitment of the standard pin from your existing bolt. Spare Plunger and Spring Included.
