New for 2021, the 4-20x50 F1 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 while offering a 25% improvement in magnification over the 4-16x42 F1. With Digillum, a ZeroStop turret, power throw lever, ED lenses, and 20x max magnification, the ATACR 4-20x50 F1 is our apex mid-power scope.

Horus TREMOR3™ - Illuminated C637

The Accuracy 1st – Speed Shooting Formula is built right into the elevation hold of the reticle making even faster shooting possible.  It’s field-proven to make wind calls easier.  The reticle also allows one to accurately mil targets very quickly. Illuminated version. 

MIL-C™ F1 C643

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. 

Range estimation
The Nightforce MIL-C™ reticle can provide you with an accurate distance to your target, when the size of the target is known, by utilizing one of the the following Mil relation formulas:

(Target Size in Inches ÷ Image Size Measured in Mils in Reticle) x 27.77 = Distance in Yards
(Target Size in Inches ÷ Image Size Measured in Mils in Reticle) x 25.4 = Distance in Meters
(Target Size in Centimeters ÷ Image Size Measured in Mils in Reticle) x 10.93 = Distance in Yards
(Target Size in Centimeters ÷ Image Size Measured in Mils in Reticle) x 10 = Distance in Meters
For example, a standard stop sign measures 30” tall x 30” wide. Knowing the size of the target, in this case, a stop sign, and applying the correct formula above, you will be able to accurately calculate the distance to your target.

Known target size = 30”
Image size = 2.5 Mils. To measure image size of target in Mils, refer to the reticle diagram above.
Divide target size (30”) by image size in reticle (2.5) = 12
For distance in yards, multiply 12 x 27.77 (constant) = 333.24 yards to target.
For distance in meters, multiply 12 x 25.4 (constant) = 304.8 meters to target.
Your ability to accurately measure your target in your reticle does take some practice to become proficient.

MOAR™ F1 C642

The Nightforce MOAR™ reticle is a major advancement in precision shooting. A floating center crosshair two MOA wide and two MOA tall provides a precise aiming point— especially on smaller targets at longer ranges. One-MOA elevation and windage spacings provide for more accurate rangefinding and hold-offs compared to ordinary reticles with coarser markings.

The MOAR™ F1 reticle features 1 MOA elevation and windage markings for accurate range finding and hold-offs.  A floating center crosshair and bold 3, 6 and 9 o’clock posts make this reticle fast and easy to use in the field.  This MOAR™ F1 reticle features over 80 MOA of elevation below center and total windage of 40 MOA on most models and 80 MOA on NX8 models.

MIL-XT™ C644

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.
