Breakthrough Clean Nylon Bristle Bore Brush .357/.38/9mm #8-32 Thread

The Breakthrough Clean Nylon Bristle Bore Brush is a pistol-caliber cleaning brush sized for .357 Magnum, .38 Special, and 9mm handgun bores. Built around a brass core with nylon bristles, this brush scrubs carbon, powder fouling, and leading from the bore.

The brush threads onto any cleaning rod using the #8-32 thread pattern, matching the standard small-caliber cleaning rod thread used across most pistol cleaning kits. The brass core provides a secure stem that threads up cleanly, while the nylon bristles flex and conform to the rifling to deliver scrubbing contact along the full length of the bore. Sized correctly for .357/.38/9mm chambers and bores, it is a practical pick for revolvers and semi-auto pistols chambered in these popular calibers.

Whether you are running a quick post-range clean or working through a deep cleaning to restore accuracy, this nylon bristle bore brush is a dependable addition to any pistol cleaning kit. Pair it with a quality cleaning rod, appropriate patches, and Breakthrough Clean solvents for a complete bore-cleaning system that keeps your handguns running smoothly.
