Pro-Shot 12C 12 Gauge Chamber Brush - Bronze

The Pro-Shot 12C is a replacement 12 Gauge chamber brush designed to scrub fouling, powder residue, and carbon build-up from the chamber of any 12-gauge shotgun. It uses the same heavy-duty brush found in Pro-Shot's chamber cleaning tool kits, making it a perfect stand-alone replacement or a spare to keep on hand.

The brush features phosphor bronze bristles crimped into a brass core, giving it the stiffness to remove baked-on fouling without scratching the chamber wall. The 5/16-27 threading matches the American standard for shotgun cleaning accessories, so it threads directly into most cleaning rods and chamber tools.

A chamber brush is especially useful on semi-auto shotguns like the Remington 1100 and Winchester Super X, where gas cylinder and chamber fouling can affect cycling reliability. For heavy cleaning sessions, the brush can also be chucked into a cordless drill to speed up scrubbing.
