Breakthrough Clean Phosphor Bronze Bore Brush .44/.45 Cal #8-32 Thread

The Breakthrough Clean BT4445PBBB Phosphor Bronze Bore Brush is purpose-built for scrubbing fouling out of .44 and .45 caliber pistol bores. A rugged brass core is twisted tight so the brush holds its shape and drives the bristles firmly down the bore, while stiff phosphor bronze bristles scour heavy carbon, lead, and copper fouling from the rifling without scoring it.

The brush uses a standard #8-32 thread, making it a drop-in fit for most standard pistol-caliber cleaning rods on the market. Phosphor bronze is the more aggressive option over nylon and is typically chosen by shooters who run a steady diet of jacketed and lead bullets through revolvers and 1911-pattern pistols and need real bite to strip residue out of the grooves.

Sold as a single brush per package. Pair it with a quality bore solvent and cleaning patches for a complete pistol-bore cleaning routine.
