Sorry if this has been discussed, but I'm fairly sure a blued barrel won't match the factory finish. What finish needs to be done to match the receiver? Besides just stripping it too and reblueing the whole job? Second question I have stripped my bolt handle of its blueing as I reworked it to my liking what could be used to make it more rust resistant should I choose to leave it in the white? Besides oiling it ect. Any help would be appreciated Thanks guys.
