KleenBore Phosphor Bronze Bore Brush .35 Rifle /9mm Pistol Caliber Carbine

The KleenBore Phosphor Bronze Bore Brush for .35 Rifle and 9mm Pistol Caliber Carbine is a precision cleaning tool engineered for safe, effective removal of fouling and powder residue from rifled bores. Unlike crimped-wire alternatives, this brush features straight phosphor bronze bristles that deliver superior cleaning power while remaining stout enough to withstand downrange pressure without collapsing or bending. The bronze construction is specifically formulated to avoid damage to the rifling grooves—a critical consideration for operators and shooters who demand both clean bores and preserved barrel longevity.

The dual-caliber design accommodates both rifle and pistol applications, making this brush a versatile choice for mixed-caliber arsenals. The straight-bristle geometry increases contact surface area in the bore, translating to faster carbon and copper removal compared to crimped designs. This is especially valuable during high-round-count training sessions or after extended shooting where powder residue buildup can affect accuracy and barrel condition. The compact dimensions (0.7 x 0.65 x 3.9 inches) and lightweight profile (0.01 lbs) integrate seamlessly into field cleaning kits and range bags without adding bulk.

This brush is ideal for tactical operators, competitive shooters, law enforcement personnel, and civilian enthusiasts who prioritize bore maintenance as part of responsible firearm stewardship. Whether performing post-range cleanup or conducting preventive maintenance during extended field operations, the KleenBore A181 delivers the mechanical advantage needed for efficient, non-damaging barrel cleaning across pistol carbine and rifle platforms.

KleenBore has maintained a reputation for manufacturing precision bore cleaning implements for decades, and the phosphor bronze brush line reflects that heritage—simple design, proven materials, and no-compromise construction that resists gumming or bristle dropout under field use.
