Hoppe's Black Copper Cleaner 4 oz. Bottle

Hoppe's Black Copper Cleaner in a 4 oz. bottle is a specialized bore cleaning solvent engineered for shooters who need to remove copper fouling and buildup from firearm barrels. Modern ammunition produces significant copper residue, particularly in rifle bores where velocity and pressure are highest. This cleaner targets that specific problem with a formula that dissolves copper deposits without damaging bore steel or leaving corrosive residue.

The 4 oz. bottle size makes it practical for range sessions, competition shooters, and routine maintenance cycles. Copper fouling affects accuracy and increases friction inside the bore; it accumulates faster in high-velocity calibers and rifles shot in rapid strings. Hoppe's Black Copper Cleaner is formulated to be safe on any firearm bore—including modern composite and polymer-lined designs—while delivering the cleaning power needed to restore bore condition between range visits. The concentrated formula means a bottle lasts through multiple cleaning cycles when used as directed.

Shooters focused on accuracy maintenance—whether competitive rifle shooters, precision handloaders, or hunters preparing rifles for the season—recognize that copper removal is essential to consistent velocity and shot placement. Unlike general-purpose gun oils, this cleaner targets the specific chemistry of copper deposits. Paired with standard bore brushes and patches, it integrates into any established cleaning routine without requiring special tools or safety precautions beyond normal firearm handling.
