FrogLube

New or old, it’s worked so far in all of my firearms.

I’ve used Froglube in all of my firearms. From my Brand new M&P40, to my 1970 S&W Mod. 60, to my 1943 Mosin-Nagant, and soon to my 1946 Remington Model 11. It has not once failed to deliver as advertised. Sometimes I open a bottle of the old stuff and sit out while working on them just to be nostglic.
