Formulated especially for bench rest shooters, Bench Rest-9 is the standard by which all copper solvents are judged. Bench Rest-9 makes it possible for bench rest shooters and serious hunters to clean their bores of copper fouling overnight...instead of 3 or 4 days. Powerful, safe and fast, and contains no abrasives. It is also great for removing powder, lead and plastic fouling from all shotguns, pistols and revolvers.
