Breakthrough Clean Nylon Bristle Bore Brush .50 Cal #8-32 Thread

The Breakthrough Clean BT-50NBB Nylon Bristle Bore Brush is a dedicated .50 caliber bore brush built around a rugged brass core fitted with stiff nylon bristles engineered to attack heavy carbon build-up and fouling inside .50 caliber firearm bores.

A standard #8-32 thread pattern on the brass core lets the BT-50NBB thread directly onto virtually any cleaning rod or handle with a matching 8-32 male end, so it drops straight into most .50-caliber cleaning kits. The brass core holds its concentricity through repeated use with solvent, while the stiff nylon bristle profile scrubs fouling from the bore wall during routine cleaning sessions.

Designed for one-at-a-time scrubbing passes with your favorite bore solvent, this single Breakthrough Clean nylon bristle bore brush is an essential consumable for shooters who run .50 caliber rifles or pistols and want a clean, accurate bore after every range session.
