Nikon and Leupold Finish

I want to use a Nikon mount for mounting my Leupold Scope. Does anyone know if the Silver Shadow Finish for Nikon is the same or VERY close to the same finish for Leupold?

Also would Leupold Rings fit on a Nikon Mount?

(The only reason I am going with a Nikon mount is because Leupold doesn't make the Silver base for my gun.) Thanks.[url][/url]
