I just ordered a Browning X Bolt, and I am considering the Talley Integrated aluminum rings/bases for it. Anyone have any experience with these, are they good quality? I usually get the Leupold steel dual dovetail rings and bases for my rifles. I will be mounting a Leupold VX-R 3-9x 50mm with a 30mm tube...always with Butler Creek flip open scope covers. Talley lists the 740735 medium height for scopes up to 50mm, and the 750735 high for scopes up tp 56mm. Any advice on which ones to get? Thanks in advance.
