Hrm. Worth looking at. MAP? That discount looks like it would bring the ATACR down into the price point of an NXS anyway.
So I had to go to the NF website... I didn't realize they still made the NXS. Personally, I'm a FFP snob and NF doesn't make a NXS F1 anymore, which is why I was mentioning the ATACR. If SFP is okay with you, then I can understand going with the NXS. Either way, I'd still try and do the .mil pricing through NF to knock even more money of the NXS.
MAP is Minimum Advertised Price. It's possible to get a new NF scope for less than MAP, but generally it's not that much lower and if NF finds out, they get cranky at the retailer. The .mil pricing list will show every single product with a reduced price off of MAP. All you have to do is email NF and they'll send it. I emailed from my NMCI account and it made it even simpler.
