I have a Savage FCP HS Precision in .308 WIN and just had the barrel threaded. I already installed the muzzle break for my suppressor that is currently in jail. My question is if there is anything I should do to the exposed metal from the threading? It is currently not blued. I keep my guns in a safe with a dehumidifier and it is unlikely (although not imporrible) that this gun will see inclement weather beyond the Florida humidity on a trip to the range. Is a good coat of oil on the threads before putting on the muzzle break sufficient? Gun grease better?

Any advice is greatly appreciated. Thank you.
