Breakthrough Clean Phosphorus Bronze Chamber Brush .308/7.62mm 3" #8-32 Thread - AR-10

The Breakthrough Clean Phosphorus Bronze Chamber Brush is purpose-built for the .308 Winchester / 7.62mm AR-10 platform, delivering aggressive scrubbing action where carbon fouling collects most stubbornly in the chamber throat.

Featuring a rigid brass core wrapped in stiff phosphor bronze bristles, this chamber brush attacks baked-on carbon and stubborn fouling without damaging the bore. The twisted brass core holds the brush firm under pressure, producing a deeper cleaning action than standard nylon brushes and driving bristles into every contour of the chamber for a complete scrub.

Cut to a compact 3" length and fitted with a standard #8-32 male thread, the brush threads directly into most popular cleaning rods and accessories that accept the common #8-32 fitting. Pair it with Breakthrough Clean solvent for a fast, thorough chamber clean on AR-10 rifles, bolt-action .308s, and any other .308 / 7.62mm chamber you need to keep spotless.
