KleenBore SC205 ChamberMate 12 Gauge Chamber Brush Phosphor Bronze

The KleenBore SC205 ChamberMate Chamber Brush delivers targeted cleaning power specifically engineered for 12-gauge shotgun chambers. This specialized brush removes stubborn fouling and residue that standard cleaning rods cannot reach effectively. Professional gunsmiths and competitive shooters rely on chamber-specific brushes to maintain peak performance and prevent extraction issues.

What Makes This Different

Unlike generic bore brushes, the SC205 features a precisely sized brush head that matches 12-gauge chamber dimensions exactly. The phosphor bronze bristles provide optimal stiffness for scrubbing without scratching chamber walls. Standard cleaning methods often miss the critical chamber area where carbon buildup causes feeding and extraction problems.

Key Features

• Phosphor bronze bristles resist corrosion and maintain shape through repeated use
• 5/16-27 thread pattern fits most standard cleaning rods and handles
• Chamber-specific diameter ensures complete contact with all surfaces
• Bristle density optimized for removing carbon and powder residue
• Durable construction withstands aggressive scrubbing action
• Compatible with all 12-gauge shotgun chambers including semi-automatic and break-action designs

Carbon buildup in the chamber area creates extraction difficulties and can cause shells to stick after firing. The SC205 addresses this problem by reaching areas that bore brushes miss entirely. Waterfowl hunters firing multiple boxes per day and trap shooters running high-volume practice sessions benefit from regular chamber maintenance. The phosphor bronze material removes stubborn fouling without damaging the chamber finish.
