The KleenBore SC225 ChamberMate is a purpose-built 12 gauge shotgun cleaning tool designed to tackle fouling where it matters most—inside the chamber and choke. If you shoot shotguns regularly, you know that plastic wads and powder residue build up fast in the chamber, and that crud affects reliability and longevity. This tool handles that job with a straightforward, durable design: a large-diameter aluminum rod paired with a heavy-duty phosphor bronze chamber brush, all mounted on a fixed T-handle for solid control and leverage. It's the kind of kit that belongs in every shotgunner's cleaning box.
The fixed T-handle design gives you a comfortable grip and enough leverage to work the brush through fouled chambers without excessive force. The aluminum rod is engineered to last, and the #5/16-27 thread size is standard for 12 gauge shotgun cleaning tools. The phosphor bronze brush itself is what does the real work—it's aggressive enough to scrub out stubborn plastic and powder buildup, yet gentle enough not to damage the chamber. Many shooters also find the ChamberMate useful for cleaning muzzle ports during extended shooting sessions, making it a versatile addition to your range kit.
KleenBore makes this tool in the USA, and that heritage shows in the no-frills, functional design. There's no plastic, no wobble, and no pretense—just a working tool that serves a specific need and does it well. Whether you're a competitive shooter, a hunter who demands reliable cycling, or someone who simply takes pride in keeping their shotgun clean, the ChamberMate earns its space in your gun care lineup.

Yes, the SC225 ChamberMate is designed specifically for 12 gauge shotguns with standard #5/16-27 threads, which is the most common thread size for 12 gauge cleaning rods.
Attach the phosphor bronze brush to the aluminum rod using the #5/16-27 threads, then work it back and forth through the shotgun chamber with your cleaning solvent to break up plastic wads and powder fouling. The fixed T-handle gives you the grip and control you need for this work.
The ChamberMate is also useful for cleaning muzzle ports during extended shooting sessions, and the durable construction makes it reliable for general 12 gauge bore cleaning as well.
The SC225 is a dedicated chamber cleaning tool—it includes the aluminum rod, phosphor bronze chamber brush, and fixed T-handle. You'll need separate bore brushes and patches for full shotgun cleaning, but this tool excels at the chamber-specific work other general kits leave undone.
