I just bought a Benelli M4 with the Chrome lined barrel. I have looked everywhere for information on what kind of solvent bore cleaner and oil to use for Chromium. I'm really afraid to use just anything.
I found M-PRO 7 GUN CLEANER (http://www.brownells.com/aspx/NS/sto...PRODUCTS#specs ) that is supposedly "harmless to all metal surfaces, including titanium, aluminum and carbon-discolored stainless steel," but does that mean Chromium? Any of you guys know? Appreciate the help.
