Not sure if there's a definitive "made in..." for the Nightforce line of scopes over the years. Seems to change with time. For a time period the NXS compacts were labeled USA while the other NXS scopes were Japan. Not sure if that holds true currently.

Of the NF scopes I have (as labeled on the optic):

3.5-15x50 NXS MLR (Japan)
3.5-15x50 NXS Mil-R (Japan)
5.5-22x50 NXS MOAR (Japan)
3.5-15x50 F1 NXS NP-RF1 (USA)
3.5-15x50 F1 NXS MD2.0 (USA)
2.5-10x32 NXS compact MOAR (USA)
2.5-10x32 NXS compact MOAR (USA)
2.5-10x42 NSX compact IHR (USA)

4-16x42 ATACR F1 Mil-XT (USA)
5.5-25x56 ATACR Mil-R (Japan)
5.5-25x56 ATACR F1 Mil-R (USA)

3-10x42 SHV MOAR (Japan)
