KleenBore Phosphor Bronze Bore Brush .338/8mm Rifle

The KleenBore Phosphor Bronze Bore Brush .338/8mm Rifle is an essential maintenance tool designed for shooters and gunsmiths who demand precision cleaning and barrel longevity. Built specifically for medium to large caliber rifle bores, this brush addresses the critical need for proper bore conditioning after live fire and between storage intervals. Whether you're running a precision bolt-action rifle, semi-automatic platform, or service weapon in .338 or 8mm, consistent bore maintenance prevents fouling accumulation, copper deposits, and corrosion that degrade accuracy and firearm reliability.

Constructed from phosphor bronze bristles, this bore brush offers a softer, non-corrosive alternative to steel that effectively removes lead, powder residue, and jacket material without scoring or damaging precision rifling. Phosphor bronze's inherent properties make it ideal for sustained use with solvent systems—the material resists chemical degradation while maintaining bristle integrity across hundreds of cleaning cycles. The compact 3.85-inch length integrates seamlessly with standard rod-and-handle cleaning systems, allowing controlled bore passage and targeted scrubbing action in the chamber and leade areas where fouling concentrates most heavily.

Law enforcement armorers, military personnel, and civilian competitive shooters benefit most from the KleenBore Phosphor Bronze Bore Brush .338/8mm when maintaining rifle systems subject to high round counts or demanding accuracy standards. The brush is fully compatible with standard 8mm and .338 caliber bores—including .338 Lapua Magnum, .338 Norma Magnum, 8x57 IS, and similar profiles—and works in conjunction with bronze-compatible solvents for optimal results. Regular bore brushing using this tool extends barrel life, maintains shot-to-shot consistency, and supports the deep cleaning protocols required by professional and precision shooting disciplines.
