Brownells
Keep your 10mm and .40 caliber handgun chambers clean and debris-free with this 12-pack of Brownells chamber brushes. A proper chamber brush is essential maintenance gear for any serious handgun shooter—it scrubs out fouling, carbon buildup, and primer debris that can affect reliable feeding and extraction. These bronze brushes are sized specifically to fit 10mm and .40 chambers, so you get an aggressive clean without undersizing or oversizing the brush to your bore.
Each brush features phosphor bronze bristles wound around a looped shank, a proven design that handles stubborn carbon without damaging chamber walls. The 8-32 male thread fits standard rod-mounted cleaning systems, so they'll work with most popular handgun cleaning rods and kits. The 12-pack gives you plenty to stock your range bag, keep a set in your cleaning kit, and share spares with shooting buddies.
Whether you're a competitive shooter putting through high volume, a hunting handgunner maintaining your carry piece, or a reloader who needs pristine chamber conditions, these chamber brushes earn their place in your maintenance rotation. Bronze won't scratch hardened steel, and the aggressive bristle design makes short work of the buildup that alone-bore brushes can't reach.
| Caliber | 10mm / .40 |
| Brush Type | Chamber Brush |
| Bristle Material | Phosphor Bronze |
| Thread Size | 8-32 Male |
| Quantity | 12 Pack |
Yes—the 8-32 male thread is the standard for handgun cleaning rods, so it'll thread into most common rod systems you'll find in a cleaning kit.
Absolutely. Phosphor bronze is soft enough that it won't scratch hardened steel chambers, but aggressive enough to scrub out carbon and fouling effectively.
Chamber brushes are sized larger than bore brushes and designed to reach the unique shape of the chamber where your round sits. A bore brush won't adequately clean chamber walls, and a chamber brush won't fit the barrel bore. Using both keeps your handgun running reliably.
Thread it onto your cleaning rod, apply gun solvent, and scrub the chamber thoroughly in and out. Follow up with a chamber patch to clear out solvent and loosened debris before you fire.
