Pro-Shot’s Copper Solvent IV® is a next-generation synthetic bore cleaner specifically engineered to remove stubborn copper and powder fouling while helping protect firearm bores from rust and corrosion. Trusted by competitive shooters, federal law enforcement professionals, gunsmiths, and accuracy-minded marksmen around the world, Copper Solvent IV has earned a reputation for delivering championship-level results.

With numerous rifle and pistol shooting championships to its credit, Copper Solvent IV helps shooters maintain the accuracy, consistency, and performance demanded by today’s precision firearms.

How It Works

Unlike traditional bore cleaners that rely on harsh chemicals and strong ammonia-based formulas, Copper Solvent IV utilizes a proprietary blend of positively charged ions and activated cleaning additives designed to target copper fouling at the molecular level.

These positively charged ions are attracted to negatively charged copper and copper oxide deposits found inside the bore. Once bonded, the copper fouling is released from the barrel surface, allowing it to be removed efficiently while leaving behind a cleaner, smoother bore.

The result is exceptional copper and powder fouling removal without the harsh odors, aggressive chemicals, or potential damage associated with conventional cleaners.

Superior Bore Cleaning Performance

• Removes heavy copper fouling and powder residue
• Helps maintain peak firearm accuracy
• Conditions the bore for easier future cleaning
• Safe for routine use on precision rifles, hunting rifles, handguns, and competition firearms
• Trusted by championship shooters and professional firearm users

Built-In Rust & Corrosion Protection

Copper Solvent IV not only cleans but also leaves behind a light protective oil film that helps guard against short-term rust and corrosion. This added protection helps preserve barrel life and maintain firearm performance between shooting sessions.
