Nightforce C643 ATACR 4-20x50 F1 ZeroStop .1 Mil-Radian DigIllum PTL Mil-C Riflescope w/Flip Up Covers

New for 2021, the 4-20×50 F1 fills an important magnification range in the ATACR line. Equally at home atop a bolt action or a semi-automatic rifle, the 4-20×50 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.

Reticle Details

The MIL-C has a simple center dot for a fine aiming point, while the main lines feature .2 Mil-Radian holds. Each whole Mil-Radian is numbered for fast reference under even stressful conditions. The MIL-C features the inverted “T”Mil-Radian ranging scale made famous in our MIL-R reticle. This allows for easy and logical estimations as low as .05 MilRadians if needed.
