BACK-BORE reamers are essential for shops doing shotgun work, such as choke and barrel modifications, available in .005" increments from .725" to .740" for 12 gauge.
Reamers have a lead angle to match most chokes, allowing for back-boring close to the muzzle for constriction or enlarging the bore for competitive shooters.
Constructed from M-7 high speed steel, these 5" long reamers are designed to remove pits from rough bores, improving appearance and performance more effectively than grinding or polishing.
