Breakthrough Clean Phosphorus Bronze Bore Brush .270/.284/7mm #8-32 Thread

The Breakthrough Clean Phosphorus Bronze Bore Brush is purpose-built for scrubbing .270 Winchester, .284 Winchester, and 7mm rifle bores. It pairs a rigid twisted brass core with stiff phosphor bronze bristles for a deeper cleaning action than nylon brushes, attacking heavy carbon and powder fouling without damaging the bore finish.

Sized to fit these popular hunting and long-range calibers, the brush threads onto any standard cleaning rod with a #8-32 thread pattern, making it a direct replacement or upgrade for most centerfire rifle cleaning kits. The phosphor bronze bristles stay aggressive through repeated use, so the same brush handles many cleaning sessions before being swapped out.

Whether you are maintaining a hunting rifle after a season in the field or scrubbing fouling from a precision rig between range sessions, this Breakthrough Clean brush delivers the bite needed to keep your bore consistent and accurate.
