Anyone have any experience with a coating for guns and magazines called Bear Coat thats put on by Rocky Mountain Arms, Inc. in Longmont, Colo.? It`s an industrial teflon thats guaranteed for life and comes in black, gray, and green. It also adds lubricity to the parts and is supposed to make them work better. I sent four new ruger factory 15 round mags to coat for me and was just wondering if anyone had tried it. Thanks, Roger
