I just purchased one myself. I've been using NF since the mid 1990's.
(before the NXS models were available)
Thought it would be just the ticket on an AR-15 varmint/predator rifle.
Usually NF is problem free, but there are two issues w/ mine.
The reticle focus/eyepiece adjustment is not right, was initially very tight and hard to move. Suddenly got very very easy to move and when the daytime reticle is in focus, the illuminated one is not.
The windage dial isn't callibrated for the internal clicks, 5 "clicks" for every 4 marks.?? Supposed to be .25 Moa per click/mark.
Probably will be sending mine back to NF tomorrow for repair/replacement.
But like I said earlier, usually they are problem free. Very happy with my older one. the only drawback they have is the weight, the 2.5-10X32 should address that though.
Hopefully, NF isn't slacking on QC because they are getting more popular and "Bigger". Seems like that happens alot anymore, companies get big and product quality goes down. Alot of them don't even worry about it until they start seeing their customers go elsewhere.
