I have a Savage 99 .308 that I am having some difficulty scoping. I have a Burris 2x7 scope that seems like it ought to be a good match for the rifle but with the 2 piece bases and rings that I have, I cannot move the scope far enough back to get the proper eye relief. Some type of extension to the rear would help but I do not know of anything like that. Does anyone have any suggestions. I am sure other Model 99 owners can relate.
