Brownells .38 Super/9mm Barrel Alignment Gauge

This tool serves as an essential barrel fitting aid for gunsmiths and an effective used gun inspection tool for dealers. The rod is designed to slide down the barrel, allowing the centered tip to align precisely with the firing pin hole on a properly fitted factory barrel. Applying a small amount of layout fluid on the breech face will reveal the exact alignment. Precision-engineered centerless ground steel for enhanced dimensional accuracy and surface finish
