I purchased one of these to go on to a Ruger scout rifle. The first one I got could not hold zero and when the elevation was adjusted sometimes the windage would move. So I sent it back and thought maybe I just got a bad one, so I returned it for another of the same. The second one was just as bad. Sent it back again and purchased a Burris FastFire III, much better. You get what you pay for!
Pros: Small & light
Cons: poor quality & One of the bad things about it is there are no positive clicks when adjusting elevation or windage
