Breakthrough Clean Phosphorus Bronze Bore Brush .357/.38/9mm #8-32 Thread

The Breakthrough Clean Phosphorus Bronze Bore Brush is a purpose-built bore cleaning tool sized for .357 Magnum, .38 Special, and 9mm Luger handgun and pistol-caliber carbine barrels. It pairs a rugged brass core with stiff phosphorus bronze bristles that scour heavy carbon build-up and stubborn residue from the bore, making it a go-to brush for routine pistol cleaning.

The brush is built on a standard #8-32 thread, the industry-standard male thread for most pistol-caliber cleaning rods and jags, so it drops into virtually any common single-piece or multi-piece rod setup already on your bench. The brass core holds its shape and threads under repeated use, while the phosphorus bronze bristles maintain the stiffness needed to attack caked-on carbon in the lands and grooves after a long range session or a carry rotation.

Designed to be used wet with a quality solvent and followed by dry patches, this .357 / .38 / 9mm brush is a staple consumable for any gun cleaning kit. It is sized correctly for the three most popular centerfire pistol chamberings in America, covering the bulk of revolver and semi-auto handgun cleaning in one part.
