Folks, Looking at one of these and would like to get out to 1000 yds. The NSX-5.5-22 has 100 moa total (50 usable up?) and all the data I can find say from 40 to 47 MOA for 1000 yards based on 100 yd zero. Will I need to find a 20 MOA base? If so, what is available for this receiver? Thanks, Joe P.
