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. SPECS: High speed steel, 12' (30.4cm) long. Gunsmith
installation required.
