I have one, it's a pretty good combat type sight. Not as good on longer ranges (over 100 yards). The reticle is a little smallish. I like the fact that you don't need a BUIS because the reticle is still visible (black) when it's turned off or if your battery runs down. I like the 3X power. If I were to do it over again, I would probably save up for an EOTech.
