They dont seem to rate much on this site, I own three of the 10X rear focus models and they have performed without a hitch, the turrets have been very consistent and the mildots are large and easy to see in low light, can be used as quick holdover hash marks with the right load and sight in yardage, as you wont always have time to use the rangefinder and spin the turrets, check out opticstalk, or the Hide, they have quite a following on some sites, good buy for 300 clams
