I don't care much for silver scopes. They seem to be a fad that goes in and out. They don't often match the gun as bugsNbows stated but neither does the gloss blackmodels. I't too muck silver for my liking. I do like a matte scope with silver rings on a stainless gun.
Here's some picturesof one of my guns set up that way.

I could have gone with matte bases and silver rings on this one. I'm doing the same to my new Sako 75 that I should have done by the end of next week.
