I'm looking for a scope base and rings for a rifle that should be coming back from the smith in a few months. It's not supposed to be an all out LR rig, rather an accurate medium weight hunting rifle that might be called upon for the odd extra long range shot. .300win mag Shilen #5 contour 26" barrel Trued Remington action McMillan Lazzaroni Thumbhole stock Badger Ord. trigger guard, mag & bolt handle. I have a NF 3.5-15x56 that I think will be get moved to this rifle but may end up using something else. I want a 1 piece base, Picatinny with the cutout that does not have much elevation. I suppose 20MOA doesn't get in the way of normal shooting, but I'd prefer something lower considering this rifle will do most of it's shooting inside 300 or 400 yards. As to the rings, sturdy but not bulky. Which base and rings fit this description?
