Well worst case scenario you can pay 25-30 bucks and get the barrel blued. Yeah they can blue stainless, or go to brownells and get a can of KG gun Kote or wheeler engineering cera kote and do it yourself in an hour. Just remember to rough up the metal with a sandblaster or 100-150 grit sandopaper/ I did it to my AR mags( I hate parkerizing on mags) and it looks friggin great. They also have a teflon moly coating that isnt as durable but sure has lubricatinjg porperties.
