I just purchased a Remington 541T/HB in mint condition, with the exception of rust spots on the first foot of the barrel at the muzzle end. The rest of the barrel and receiver are in perfect condition. Here are pics of the barrel that show the rust spots:
Gun oil, a soft cloth and some elbow grease successfully removed the rust. That revealed small flaws in the blue: you could see glints of steel at the center of some of the former rust spots and general discoloration of the blue where the rust was. So my question is:
What would you recommend to return the 541T barrel to mint or new condition? If you have prior experience with something like this, what did you do and how did it turn out?
