Mine's going on my CZ Grendel, which currently wears an Mark AR Mod1 1-4. A little more magnification will be appreciated on that one, as well as covered turrets. Hard to tell for certain without mounting it, but ther ER is clearly long and the eyebox seems good. I ran the turrets today and the clicks are very positive. A bit over 10 full rotations from one end to the other.
I'd "risk" another C note and buy a second one, but just don't have anything to put it on (and NO plans to add to the pile), and have a couple spares already.
