The Breakthrough Clean Phosphorus Bronze Bore Brush (brand part no. BT12GPBBB) is a durable bore brush built for shooters who want a deeper clean than nylon bristles can deliver without risking damage to the bore. Breakthrough Clean Technologies constructs the brush around a twisted brass core that keeps the bristles rigid under pressure, so the phosphorus bronze bristles cut through fouling instead of just brushing over it. It uses the standard #8-32 thread pattern, which also matches the standard shotgun #5/16-27 thread on .410, 28-gauge, 20-gauge, and 12-gauge applications. Each brush ships one per package, ready to thread onto any standard cleaning rod.
