I just sent 4 new factory ruger 15 round mags to a company called Rocky Mountain Arms, Inc. in Longmont, Colo. to have them coated with a finish called Bear Coat. It`s an industrial strength teflon thats guaranteed for life. It also comes in green, black, and gray. Has anyone had any experience with this finish or this company. Sure hope they turn out good. Any info would be appreciated. Thanks, Roger
