The KleenBore A178N bore brush delivers thorough cleaning for multiple rifle calibers without the aggressive scrubbing that damages barrel rifling. This versatile cleaning tool handles .25, .243, 6mm, and 6.5mm calibers with precision-cut nylon bristles that remove fouling while protecting your investment.
What Makes This Different
Unlike bronze brushes that can leave metal deposits in your barrel, the A178N uses engineered nylon bristles that maintain their shape through hundreds of cleaning cycles. The bristles flex to follow rifling contours while providing consistent pressure against carbon buildup. Standard 8-32 threading ensures compatibility with most cleaning rods, while the caliber-specific diameter maximizes contact with barrel surfaces.Key Features
