Inspired by the NXS, the ATACR family of riflescopes defines Rugged, Reliable, and Repeatable. Overbuilt with mission critical features standard which includes ZeroStop and a choice of illuminated MOA or Mil based ranging reticles. Built from the most rugged materials, ATACR riflescopes deliver benchrest precision even under the harshest conditions. Fully multi-coated ED glass results in superb light transmission, brilliant images, and exceptional color contrast. With the varying magnification ranges, the ATACR line of scopes can cover almost any situation a shooter may have. Featuring sophisticated reticles, the ATACR leaves nothing to chance. The ATACR from Nightforce redefines the "long" in long range, leaving the possibilities endless. The 4-20A-50 F1 fills an important magnification range in the ATACR line. Equally at home atop a bolt action or a semi-automatic rifle, the 4-20A-50 F1 is smaller and lighter than the 5-25A-56 F1 while offering a 25% improvement in magnification over the 4-16A-42 F1. With Digillum, a ZeroStop turret, power throw lever, ED lenses, and 20x max magnification, the ATACR 4-20A-50 F1 is Nightforce's apex mid-power scope.
