Nightforce Optics ATACR 4-20x50 F1, Mil-C Reticle, Rifle Scope

The 4-20x50 F1 rifle scope fills an important magnification range in the ATACR line.  Equally at home atop a bolt action or a semi-automatic rifle, the 4-20x50 F1 is smaller and lighter than the 5-25x56 F1.  With Digillum, a ZeroStop turret, power throw lever, ED lenses, and 20x magnification, the ATACR 4-20x50 F1 is Nightforce's apex mid-power scope.
