New for 2021, the Nightforce Optics ATACR 4-20×50 – C642 Riflescope fills an important magnification range in the ATACR line.
Equally at home atop a bolt action or a semi-automatic rifle, the 4-20×50 F1 is smaller and lighter than the 5-25×56 F1 while offering a 25% improvement in magnification over the 4-16×42 F1. With Digillum, a ZeroStop turret, power throw lever, ED lenses, and 20x max magnification, the ATACR 4-20×50 F1 is our apex mid-power scope.
