Re: best scope for SIG 516 ????
I personally have difficulty with acquisition and hold using red dot optics...don't really know why, I just don't like them. Like you, I was willing to spend some $$$ to get what I wanted. Ultimately, I went with the Nightforce 1-4x24 NXS compact on one of my Sig 556s. Mine is mounted on a LaRue LT-104 QD mount and has mil turrets, Zero Stop, and the NP-1 reticle. I've used it from 25 to 200 yd and couldn't be happier with the performance. Compared to a red or similar optic, it's fairly heavy...but I bet you could run over it with a truck and not hurt it in the least. The type of shooting I do with this rifle is similar to what you described, so I think you'd be happy with it. My .02.
