Clymer's "BACK-BORE" reamers are essential for shotgun barrel and choke modifications, with sizes in .005" increments from .725" to .740" for 12 gauge.
These reamers can be used to back-bore shortened barrels for constriction or to enlarge a choked barrel for extra constriction, benefiting competitive shooters.
Made of M-7 high speed steel, the 5" long reamers are designed for efficient removal of pits from rough bores, improving both the appearance and performance of the shotgun.
