Breakthrough Clean Nylon Bristle Bore Brush 12 Gauge #8-32 Thread

The Breakthrough Clean BT-12GNBB Nylon Bristle Bore Brush is purpose-built for 12 Gauge shotgun cleaning. It pairs a rugged brass core with stiff nylon bristles that scour the bore to lift heavy carbon build-up, fouling, and residue without being overly aggressive on the barrel wall, making it a smart choice for routine shotgun maintenance.

Threaded in the standard #8-32 pattern, the brush attaches to virtually any common shotgun cleaning rod, slotting into your existing routine as a dedicated 12 Gauge bore scrubber. The nylon bristles flex to follow the contour of the bore, while the brass core holds its shape under repeated use across many cleaning sessions, so the brush keeps scrubbing effectively long after cheaper consumables have given up.

Used with your preferred bore solvent and patches, this 12 Gauge nylon bristle brush is a straightforward, drop-in consumable for any shotgunner's cleaning kit. Nylon bristles clean fouling out of the bore without the metal-on-metal wear that comes with bronze or steel alternatives, helping preserve the interior finish of your shotgun over years of regular service.
