Anyone have a suggestion as to what comes close to the finish on my Rem SS barrel?
Absolutely nothing. IMO nothing looks worse than a stainless rifle with a bright silver scope and gold tinted nickle plated rings and bases.
Get a black matte scope and black matte bases and rings.
If you go with silver the scope will be much shinier than the stainless steel your rifle is made with and the rings and bases will very likely be another shade of "silver"... Leupold silver rings have a gold tint to them.
If you do decide to go against our great advice and get a silver scope then get DNZ products rings as the are made of hardened aluminum and will be very close to the color of the scope.
