I've had one on my 6.5 Creedmoor and shot it out to 1000+ yds. The glass is really good. The reticle is nice too. A good 0.2 Mil xmas tree style designed I believe by Ilya the 'Dark Lord of Optics'. Illumination is centre + only. The Zerostop is of the hard kind so not shim type but it takes some figuring out how it works and how to set it but there is a tonne of vertical adjustment available. The two gripes are it does not come with a sunshade as std. and only the Elevation turret is lockable whereas IMO it should have been the other way around with lockable windage turret as most people hold off for wind and dial for elevation. If they fixed a few of these issues and provided decent instructions in English especially for setting the ZS then I would rate it up there with my Bushnells and NF.
