Systema ENERGY Spring Guide with Bearing for PSG-1 Review
This Spring Guide hails from SYSTEMA's ENERGY Collection series, and is enhanced with high quality thrust ball bearings. Designed to minimize the load on the motor caused by the spring torsion especially when compressing custom springs. A side effect of this ball bearing system actually resets the spring more effectively as well! The new ENERGY Collection is manufactured ground up with state of the art technology from SYSTEMA, and is sure to provide an ehanced grouping when firing whilst delivering a much more stable level of power.
