After a few months with it now, I don't really care for the NX8, and I'd rather a better 1-6, but because it's not mine I'm stuck with it until I give up my position. I don't have problems with the low end like others, but I think the top end magnification with the reticle SUCKS. I HATE their circle dot. We did some work on 8" circles the other day from elevated position @ 180y, 240, 320, and 410y respectively from a catwalk. I struggled on the farther 2 which was never a problem prior to my optic switch. I've had a few other times when looking through it that I thought "well...this isn't ideal" in that respect.
But everything on that particular rifle/setup is a compromise and I'll continue to do my job with it, and it will likely be fine. That said, I will NOT be buying an NX8 or ATACR with my personal funds. Some guys out there love 'em and that's cool; I've been doing my scoped rifle semi-auto thing now for nearly 25 years and I know what I like to see and which features I prefer.
Breaking it down, I've never liked the daylight illuminated reticle for LPVO's; I much prefer the Aimpoint/LED/Flash Dot tech used by S&B, Kahles, Razor HD. You don't get the shimmer/flicker out of the later
As far as what I'm seeing, Kahles and anything S&B with "CC" have offered me the best image as close to naked eye as I could get. The Razor HD II E was a close second.
As I've stated before, I'll take a higher-end optic at a lower magnification at work. Time and time again, I've out-paced NF 10x's with an 8x and mid-level 6x optics with a 4x. The Kahles and Razor HD both give me a bigger, better image and are far more forgiving than the NX8.
