Best rings out there - Burris XTR Signature 34mm Rifle Scope Rings

These rings work great. They center on the rail and add as much moa as you need. You can not only gain or loss up to 40 moa of elevation by choosing the right combo of inserts but you can also adjust for unusal ring/mount/barrel alignments. By simple rotating the front or rear inserts (your choice) you can align the barrel and scope (a little trial and error in finding the correct combo). I also found the the 6 screws on the ring clamps make it easier to tighten without changing the scope level comparied to the 4 screw set up on the regular signature zee rings.
I personally like the idea of torx screws to attach the rings to the rail compared to the big nut sticking out the side to catch on.
Another plus is that the plastic inserts clamp the scope tightly without leaving rings marks on the scope barrel as Burris advertises
