I'm not sure what its made of, as far as the specific grade of steel, but I personally see no issue with chrome plating it. As long as any/all serial #s etc are still intact/legible. Might think about something like Cerekote as well. Especially if they have it in a clear. Bake on ceramic coating thats tough as nails, and has very good wear resistance. The Cerekote would probably be thinner than chrome as well, which would keep it from screwing up the dimensions, and leaving you or Mr.Floyd with having to make adjustments. My 2 cents.
