I bought this red dot to mount on the carry handle of my Stag AR, so that I could continue to use my iron sights. Installation was easy, and I calibrated it to match the military's 25m/300m zero. With this red dot, I can hit torso sized targets from 25 to 300 meters without having to close one eye. That's exactly what I wanted out of it, so I'm very happy. Of course, if you want to shoot quarter-size groups at 200 yards, this is not the optic you need. If you want to hear that satisfying "ping" of steel targets getting hit at 100-300+ yards and know that you've got a fighting chance with the zombies, give this Millet a try.
Pros: easy to use, holds zero, good price for what you get
Cons: reliability TBD
