Only Burris I tried was such a disappointment I sent it right back without even mounting it.Very poor lens quality and brightness,every Burris thread you see on any of the forums has as many or more negative responses than good.11MOA is crazy and to need offset inserts to sight it in is pretty bad.According to specs at 100yds the 6x20 Conquest 1" tube has 45 MOA of adjustment
6.5x20 Leupold Vari X lll 1" tube has 44 MOA of adjustment
6x24 Burris Signature 1" tube has 22 MOA of adjustment.

Good Luck with your sighting in,hope it all works out for you.
