Just bought one last week,non sale, from Academy for $129.99. Gave her about an 80 round test to sight in and play with it just a bit. 1. Lock it down tight. I had to retorque it a couple times, my fault for being too gentle, I'm sure. But even lose, zero held surprisingly well for minute of coffee can accuracy. 2. The dot was fuzzy, but I'm positive my astigmatism had absolutely nothing to do with that. Nevertheless, when the dot brightness was turned down, the little 2moa dot was clear enough for business. I would imagine somebody with normal eyes would see a really clear, crisp dot. 3. I like the shake awake mode. Makes it particularly nice for a night time gun when I need to provide immediate overwatch for the ongoing Pyrenees vs Coyote wars this time of year. 4. It don't weight don't diddly squat. Well, relatively speaking, of course. And the low profile seems to fit nicely to the rifle without appearing to scream, "Look! I'm tactical!" Like do many other optics often do with their cantilever mounts. So far, I'm happy. I was able to keep a coffee can rolling at varying ranges, with one or both eyes open, at my leisure. It is direct co-witness on my rifle, but the A-frame front sight in the sight picture doesn't seem to really bother me. I just fold the Magpul rear down, and away I go.
