Barnes CR-10 Bore Cleaner 8 oz.

The Barnes CR-10 Bore Cleaner 8 oz. is a specialized firearm maintenance solvent engineered for removing fouling, copper deposits, and carbon buildup from rifle and handgun bores. Formulated by Barnes Bullets—a manufacturer with deep expertise in ballistics and ammunition performance—this bore cleaner targets the specific residues left behind by high-velocity firing, particularly those from copper-jacketed projectiles that accumulate in rifled bores over time.

The 8 oz. bottle size offers a practical volume for regular maintenance routines without excessive storage requirements. Bore cleaners of this formulation work by chemically breaking down copper and powder residue, allowing them to be flushed or wiped from the bore more effectively than mechanical scrubbing alone. Users performing regular cleaning after range sessions or field use will find this product reduces the time needed to achieve a visibly clean bore while helping preserve bore integrity over extended use. The solvent-based formula is designed to penetrate fouling deposits rather than simply coat the surface.

This bore cleaner serves shooters who prioritize bore maintenance as part of responsible firearm ownership. Whether maintaining rifles for accuracy, sustaining handguns for reliability, or preserving collector pieces, a dedicated bore cleaner addresses the chemical residue that standard gun oils cannot effectively dissolve. The Barnes CR-10 is suitable for routine cleaning intervals and is a foundational component of any comprehensive bore maintenance protocol.

Bore cleaners represent a distinct category within firearm solvents—distinct from general gun oils or protective lubricants. A dedicated bore cleaner allows shooters to separate the fouling-removal phase of cleaning from the lubrication and protection phase, ensuring each chemical does its intended job without compromise.
