The following is just my personal opinion based on my personal experiences, so that it for whatever it is worth to you.
Well, I have had a good look at the ATACR, and it is a very good scope, but it is a bit above what I personally need or desire in a scope. Nightforces in general are big and heavy... in other words, solid as hell. The ATACR is definitely big, 34mm tube, 56mm objective, it is not a small scope by any means. Now other than the size, the only other real drawback is that it is **edit, thanks guys**
$400.00 more expensive over a fully kitted out NXS 5.5-22x56 with zerostop and the reticule of your choice.
My personal choice was pretty clear, as I use mine on large caliber rifles where eye relief is king.
I have owned and shot with well over 30 different types of rifle scopes from dozens of manufacturers, from cheap Chinese knockoffs to $4,000.00 + Premier Riflescope Heritage... and everything in between. The NXS 5.5-22x56 with Zerostop and MOAR is my go to scope for cost/ benefit... which lets be honest, the price goes up realllly fast at this level of the rifle scope game for small percentage improvements. The NXS is one hell of an amazing piece of kit for the cost, around 2k new and cheaper used.
I have recently purchased 3 more NXS 5.5-22x56 zerostop MOAR scopes to compliment the two I already have, and am swapping the other brands on my dedicated LR rifles, including .338LM's and .50BMGs. That is how much I believe in this particular scope. I have tons of hits out to 1000m and beyond with these scopes. I haul them through the bush unprotected, I have used them in -40c in blasting snowstorms to +35c on blazing hot days on sizzling military ranges, and muddy, raining days trekking through swamps. These scopes have taken all the hits I have dished out to them and not even been fazed.
I would without one single doubt, stake my life on the quality of these scopes.
Just to show I am not a BS'er... although I imagine a few on here already know that I back up what I say, here is some eye candy.
Here are two of the three new ones, third still in the mail... om nom nom they are so beautiful!
On my .338LM
On the semi auto .50BMG.
