New for 2021, the 4-20×50 F1 fills an important magnification range in the ATACR line. Equally at home atop a bolt action 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.
This riflescope offers an incredible field of view across the entire magnification range, making targets easy to find, identify and engage. Whether the need is for competition like the Precision Rifle Series (PRS), or extreme long range shooting, this riflescope delivers unmatched precision and repeatability.
The MIL-XT™ has a simple center dot for a fine aiming point at center, while the main lines feature .2 Mil-Radian holds. Each whole Mil-Radian is numbered for fast reference under even stressful conditions.
Below center, whole Mil-Radian intersections feature a floating dot. Dots are placed at .2 Mil-Radian increments, while whole Mil-Radians are increased in size for fast counting. Additional marks are placed at half Mil-Radian increments as well. Numbers below center alternate in size for easy counting and verification of appropriate hold points.
This reticle was designed for the competitive and field shooter, and is certain to give a competitive edge to anyone who uses it.
