[QUOTE="SidecarFlip, post: 603626, member: 39764"] Not necessarily..... Aluminum rails, unless specifically stated will be anodized black or clear anodized silver (aluminum color). Steel will be parkerized or hot mineral bath etched. Without getting into the mechanics of anodizing, it's basically a controlled oxidation of the porus surface of the aluminum and the addition of a coloring die impregnated into that surface through electrolysis. Rail choice is predicated on weight and cost considerations at least in my case. All picatinny rails, if made to the Mil Spec will be within the tolerance that spec spells out. Weaver rails are another story. Interestingly, I've shimmed backends (of scopes) as well. Never used tin foil. Used thin brass shim stock form rolled to the inner radius of the ring. 0.010 on a 6-7" rail yields about 10-12 MOA. I've also considered shimming the back rail to receiver mounting foot bit haven't done that as of yet. [/QUOTE]
