I spent over 100 rounds of .308 ammo on a bench rest trying to zero this sight at 25-60yd distances. The windage adjustment screw provided erratic target impact results. Once I got one reticle dialed in the best I could for 6-8 inch groups at 60-yds and switched to any other reticle the zero changed greatly. Also, the detent "click" is almost imperceptible for knowing when the dial is in the correct position to lock in the reticle image you are selecting. A waste of $70 as far as I am concerned.
Pros: Simple to mount on rail
Cons: Won't hold Zero for use with multiple reticles
