I put one of these on my new Ruger AR556 MPR a few months ago and I love it (see photo). The illumination is nice, but in bright daylight, I don't turn it on because the black reticle works fine. I haven't hunted with it (I'm just a range junkie), but it only took about 5 shots to zero it at 100 yards. I'd say the 0.1 minute-of-angle adjustments on the dial are kind of overkill, but as I said, I use it at the range for quick target acquisition and multiple shots, not trying to drive nails at 500 yards (although I bet it's capable of that). The first focal plane feature is also nice. At 1x it's basically a red-dot when illuminated, but at 4X, you've got cross hatches for 200, 300, 400, 500 yards.
I can't compare it to better (read: more expensive) scopes because I haven't used them. But while I may be a bit of a newbie, I do my research and the reviews for this scope all touted its specs/performance relative to price, so I think it's an excellent value. And frankly, I don't want to put an optic on my AR that makes it too precious for me to go out and shoot a lot. Isn't that the point of having a semi-auto sporting rifle?
