KleenBore SC205 ChamberMate 12 Gauge Shotgun Chamber Brush - Phosphor Bronze Bristles, #5/16-27 Thread

The KleenBore SC205 ChamberMate 12 gauge shotgun chamber brush is a purpose-built tool for removing stubborn fouling—wad buildup, unburned powder, and carbon—from the chambers of your 12 gauge shotguns. Designed with heavy-duty phosphor bronze bristles in a tapered profile, this brush reaches deep into chamber geometry to scrub out the gunk that regular patch and solvent combos can't touch. If your shotgun's had a hard day in the field or at the range, this is the specialized cleaning tool that restores chambers to like-new condition.

The #5/16-27 thread connects to standard shotgun cleaning rods and—most importantly—the KleenBore ChamberMate 12 GA cleaning tool (sold separately), which pairs with this brush to create a complete chamber-cleaning system. Whether you're dealing with heavy wad fouling from clay shooting or powder residue from hunting loads, this brush handles the job without scratching or damaging chamber walls. Made in the USA, it's a reliable addition to any shotgunner's cleaning kit.

Phosphor bronze bristles are aggressive enough to cut through buildup but won't leave marks like steel would. The tapered design fits snugly in the chamber while still allowing bristles to scrub sidewalls and the forcing cone area effectively. If you shoot your shotgun regularly, you already know that chamber fouling accumulates faster than most shooters clean—this brush makes that maintenance straightforward and thorough.

Frequently Asked Questions

Is this brush compatible with my shotgun cleaning rod?

Yes, the #5/16-27 thread is the American standard for shotgun cleaning systems, so it fits most shotgun rods and cleaning tool setups. It's also specifically designed to work with the KleenBore ChamberMate 12 GA cleaning tool (model #SC225), which you may want to pair with this brush for a complete chamber-cleaning system.

Can this brush clean areas other than the chamber?

Absolutely. The tapered phosphor bronze bristles work well on choke tubes, muzzle ports, and forcing cones—anywhere inside the bore where buildup accumulates. This makes it a versatile tool for comprehensive shotgun maintenance, not just chamber cleaning.

Why phosphor bronze instead of steel?

Phosphor bronze bristles are tough enough to scrub away fouling but won't scratch or damage chamber walls and delicate bore surfaces the way steel brushes can. This protects the integrity of your shotgun while still delivering aggressive cleaning power.

What fouling does this brush remove?

It's designed to tackle wad fouling (a common shotgun problem), unburned powder residue, and carbon buildup—the kinds of deposits that accumulate from regular shooting and can affect reliability and accuracy if left unchecked.
