I put this on a Mini-14 and am pretty happy with it. Once it was on, I only had to move the windage adjustment 4 clicks and the elevation one. The dot is fairly round at all sizes. My only complaint is the auto-brightness. If you are in a low light surrounding and aiming into a high-light area, the dot isn't bright enough. Otherwise, if you are outside the dot is bright enough. It would be the perfect scope if there was a manual brightness adjustment knob.
Pros: Adjustable dot size
Cons: Would rather have manual brightness adjustablity
