Are you wanting a SS scope to somewhat match your rifle's finish, or a matte black one? If SS might be what you'd want, Leupold makes their Shotgun VXI 2-7x33 in SS (silver) finish. That's about as big a scope as I'd want on that gun, personally. The best bases for that one might be Leupold's one piece silver standard base and low rings.
If you want a matte black scope, I'd suggest a couple, depending on your price range. The Leupold Shotgun VXI 1-4x20 with HD reticle is a good one for $200 and the Nikon Monarch African (1") 1-4x20 with #4 reticle for about $280 is a very good value. It's an exceptional scope.
