A question or 2 Why do you "want the scope as low as possible"? Does the rifle/scope combination fit you best with the scope very low? Unless you have a very short or no neck is low the best position for proper fit?
I ask only because it always amazes me how so many guys have been brainwashed into believeing that the scope must be low, rather than having your eye in the center of the ocular while in a comfortable, and more importantly, repeatable position. If you have to hunt around to find the sweetspot in your scope, you have the wrong scope height.
My suggestion is to find a decent gunshop and have them fit the scope and rings to YOU, not the other way around.
Long Distance is BETTER than being there
