Hoppe's Black Copper Cleaner is an ammonia-free bore solvent formulated to remove copper fouling from rifle and handgun barrels without the harsh fumes or corrosive properties of traditional ammonia-based cleaners.

Works effectively on both modern sporting rifles and traditional firearms without requiring extended soak times.

This 4-ounce bottle provides multiple cleaning sessions for shooters who want to maintain accuracy without exposing themselves or their firearms to aggressive chemical compounds.
