Overview

This cutter is intended for smoothing a damaged or poorly cut muzzle and for easing sharp edges at revolver cylinder chamber mouths. It is a practical bench tool for shooters who want to address issues that can interfere with accuracy or cause rounds to hang up when using speedloaders. Built from steel and offered in 1/2" or 5/8" diameter options, it provides a 45-degree chamfering cut in a compact 3-1/4" form. For gunsmithing and maintenance work, it is aimed at correcting edge conditions rather than adding features beyond the cut itself.
