Birchwood Casey 41283 Bronze Bore Brush .45 Cal/12mm 8-32 Thread

The Birchwood Casey 41283 Bronze Bore Brush is a purpose-built cleaning tool for .45 caliber and 12mm firearm bores. It pairs bronze bristles with a steel wire core to deliver the aggressive, multi-directional scrubbing action needed to strip copper, carbon, and lead fouling from pistol and revolver bores without damaging the rifling or barrel finish.

The brush threads onto any standard cleaning rod using the common 8-32 thread pattern. Its looped wire core keeps the bristles centered in the bore for thorough, even contact along the full length of the barrel. Bronze is the preferred bristle material for removing jacket-metal and lead deposits while remaining gentle on the bore surface.

The 41283 is sized to fit .45 ACP, .45 LC, and .410 handgun and revolver bores, as well as any 12mm firearm bore, making it a versatile addition to a routine cleaning kit. Pair it with a quality bore solvent and patches on a compatible cleaning rod for complete bore maintenance.
