Helps Align Bolt For Straight Lock-Up, Smooth Cycling
Steel reamer gives a precise .715" bolt-way cut to correct any variance along length of any .700" diameter bolt tunnel in the action. Tapered pilot bushing (.700" - .705") inserts into tang end of action to ensure straight reaming. Includes two .7145" bushings for use with other Manson tooling. Bolt must be shimmed for proper fit in oversized way.
