The optics are the clearest and brightest I've seen. I have been using red dot optics for almost 20 years and this is the best red dot I've ever used. It's perfect and high quality in every way. Zeroing the dot is precise and each turn of adjustment moves the dot a specific amount; a couple other mini red dots I've owned would move the dot unresponsively while trying to adjust zero. This one is reassuring in response and gives you confidence that the dot will be on zero every time. I have two of these by the way, I like the so much. The only reason I qualify it for civilians is I feel the Trijicon RMR would be stronger for severe duty or throwing the gun around in a military environment.
Pros: bright glass and dot (triangle), quality construction, light weight and easy zeroing
Cons: battery replacement requires removing scope
