I don't believe Bushnell is advertising a matched scope. Also I think that ruger has at least three different SS finishes. There mini 14 looks galvanized and I have seen some of there rifles that are a matte SS and some that are a polished SS. Its pretty hard to match scopes to rifles sometimes, I hear of problems with it everyday. If any would match it would be to a matte SS rifle.
I've always liked the look of a black scope on a SS gun as long as the rings match the rifle and it had a black synthetic stock.
