Developed for the military's extreme long range shooting and hard target acquisition, the 5.5-22x50 and 5.5-22x56 NXS provide broad and magnification and range, combined with a large field-of-view, four inches of eye relief and 100 M.O.A. elevation travel. This range of magnification and internal adjustment allow most .50 BMGs to achieve the 2,000-yard mark with accuracy. These NXS models are numbered among the most advanced field tactical scopes ever produced. Nightforce established new standards for performance when we debuted these scopes, and they remain the benchmark by which all other scopes are measured.
