KleenBore Phosphor Bronze Bore Brush 20 ga Shotgun

The KleenBore Phosphor Bronze Bore Brush 20 ga Shotgun is an essential maintenance tool for law enforcement, military personnel, and serious sport shooters who rely on 20-gauge shotguns for duty, training, or competition. Proper bore cleaning is crucial for maintaining firearm reliability and longevity, as carbon, lead, and powder residue can accumulate rapidly in shotgun bores.

This dedicated brush is designed specifically to remove fouling from the bore diameter of 20-gauge shotguns without damaging rifling or forcing cone geometry. Constructed from phosphor bronze, it offers superior corrosion resistance and durability compared to standard brass alternatives, making it ideal for wet environments and extended storage cycles.

The compact 3.55-inch length and 0.95-inch diameter ensure a proper fit and control when paired with standard cleaning rod systems, delivering effective fouling removal without risk of bore damage. This brush is compatible with all standard 20-gauge shotgun platforms, including pump-action, semi-automatic, and break-action designs.
