I have this mount on my AR15 for some long range varmint (especially coyote) control. I've only had it a couple months and have only used it on paper targets at 40 - 125 yards. It's good but in low light it loses a lot of clarity. It's also heavy. The illuminated reticle is nice, and I'm getting a hang of using the mil-dot-bar. Its construction feels very solid. Comes with basic flip-up caps, 3" sun shade, a sock cover, and allen wrench. Fit and finish is excellent. The knobs and rings are great with solid clicks, not too loose and not too tight, the zoom click on 10x is nice. I've mounted mine with a Burris PEPR mount and it's great! If you can get it on a good sale, go for it.
