Eclipse Shaft FR Back Kits

The Eclipse Shaft FR ("FreakTM Ready") Barrel Back is compatible with "FreakTM" inserts* for optimized bore selection. The Shaft FR back assembles in a unique manner so that the ball is guided into the Insert via a tapered opening at the rear. The insert is held in place by the Joiner section which doubles as the interface to the Tip. The Shaft FR back has 3 windows that make it possible to quickly and easily identify which insert is being used as well as "Quick Threads" that allow the barrel to be attached and removed from your marker in less than half the time when compared to standard Cocker threaded barrels.
