Manson Reamers Muzzle Crown Refacing Tool Kit 5 Pilots

The Manson Reamers Muzzle Crown Refacing Tool Kit can be used to reface or completely form precision muzzle crown on rifle, shotgun and handgun barrels made from commonly used carbon, alloy orstainless steel, including chrome lined barrels. No further deburring, lapping or polishing of bore edge is necessary. Carbide blades are set-up at the factory to cut muzzle end of the barrel with outside diameter of no more than 1 1/8 " and minimal bore diameter of 5.5 mm, but blades can be moved outward to increase outside diameter to 1 3/8" if necessary. If blades were moved or replaced, make surethat all screws holding blades in place are tight.
