I have an Accuracy International AT-X on order and I am wondering what Spuhr mount should I purchase for my Nightforce ATACR 7-35 scope. I intend to use the full bridge on the AT-X and the short picatinny rail on the front portion of the bridge. Should I purchase the Spuhr SP-4602 1.5 with the 20 MOA or should I get one with O MOA? Or should I go lower with a Spuhr mount that is 1.35?
