KleenBore Phosphor Bronze Bore Brush 20 ga Shotgun

The KleenBore Phosphor Bronze Bore Brush 20 ga Shotgun (Model A184) is a precision-engineered cleaning tool designed for safe and effective removal of fouling, powder residue, and carbon buildup from 20-gauge shotgun barrels. Built with straight phosphor bronze bristles rather than crimped wire, this brush delivers superior scrubbing action while protecting rifled surfaces from damage during the post-shoot cleaning cycle.

The straight-bristle design maximizes contact area inside the bore, allowing fouling to be stripped away more efficiently than crimped alternatives. Phosphor bronze is the industry standard for shotgun bore brushes because it is softer than steel and will not scratch or degrade the protective bluing or nickel plating on barrel walls. The brush maintains structural rigidity—its thick, stout construction resists bending under normal cleaning rod pressure, ensuring consistent performance across multiple cleaning sessions without bristle deformation or premature wear.

This brush is essential maintenance gear for shotgun operators, competitive shooters, hunters, and law enforcement personnel who rely on reliable bore cleaning after range training or field use. Whether you shoot lead, steel, or lead-free ammunition, buildup accumulates quickly in 20-gauge patterns. Regular use of a quality bore brush prevents corrosion, maintains accuracy by keeping the bore clean, and extends barrel life. The lightweight, compact design fits standard cleaning rod setups, making it a practical addition to any shotgun maintenance kit.

Kleen Bore brushes are recognized in the firearms maintenance market for precision manufacturing and material consistency. This 20-gauge brush pairs with standard .20 caliber shotgun cleaning rods and patches, integrating seamlessly into existing cleaning protocols without requiring proprietary equipment or adapters.
