RE: Moly Fusion
I tried running it on the rails one of my competition pistols, didn't see any difference after several applications. I can't remember if it has teflon in it, do not put anything with teflon in it down your barrel.
Teflon in your barrel doesn't create a safety hazard, but it has been shown to decrease accuracy because it imbeds itself in the pores of your barrel causing your bullets to not ride the rifling as they should.
I'd save my money for something else.
