The Pro-Shot Shotgun Chamber Tool and Brush (Pro-Shot part no. CH12) is an 8-inch non-swivel tool built for 12 gauge shotguns, with a large chamber brush designed to make removing residue from the chamber easy. Chamber fouling in a shotgun can cause misfires and poor ejection, and this tool is aimed directly at clearing that problem, particularly on semi-auto shotguns where reliable cycling depends on a clean chamber. The non-swivel handle gives more direct control than a swivel-handle rod would in the tight quarters of a chamber. The brush itself is replaceable, so the tool has a long working life beyond the first worn-out brush.
