Does anyone have any experience with Weaver scopes? I have a chance to purchase a N.I.B. Model 800704 'Classic Extreme' 2.5-10 x 50 rifle scope from a friend who no longer has a use for it. He is asking $300 for it. It has an illuminated reticle. It seems pretty bright and clear glass. I would mount it to a 30-06 Savage bolt gun. Any advice would be greatly appreciated.
