Got a copper problem? Hoppe’S Bench Rest 9 Copper 5 oz Gun Bore Cleaner can fix it. Shooting rounds down your barrel causes copper fouling where the jacket of the bullet meets the grooves. Hoppe’s cleaner removes the residue restoring your barrel back to bare steel. As copper builds up, it can change the velocity of your rounds causing issues and carbon to build up.

- Removes copper fouling
- Removes plastic and carbon residue
- Available in 5oz plastic bottles
- Use gloves while cleaning
