hi folks my AI was no way reaching the 1k line, as the nxs only had 18minutes of elevation left from a 100yrd zero. couple this with the fact that the burris dealership is in the process of changing just now and i was pretty much goosed. however, my hat goes off to pete lincoln at http://www.roedaleprecision.com, who answered my cry for help and sorted me out with the sws2000 mount shown below. a beautiful and excellently made one piece mount with 20moa (i think) slope and i am now ready for the 1k line. cheers pete.
