NX8 - 2.5 - 20x50mm F1 - ZeroStop-.1 Mil-Radian-Digillum - PTL -Mil C (NF-C623)

There's a very good reason why most variable-power riflescopes have relatively modest magnification ranges, usually no more than a multiple of five or six (for example, a 3-12x is a multiple of four). While it has certainly been possible to build a riflescope with a multiple of eight, building one that delivers exceptional clarity, resolution and brightness at every setting, across the entire magnification range, has been a major obstacle for optical engineers. Until now. Our new NX8 2.5-20x50 F1 gives you one riflescope that will rule virtually any shooting environment, anywhere on Earth, at almost any distance. It includes advanced DigIllum reticle illumination. Nightforce ZeroStop technology. Your choice of MOA or Mil-Radian adjustments. And the power of eight comes in a sleek, streamlined package a mere 12 inches in length. It just might be the only riflescope you will ever need.
 
MIL-C™ F1 Reticle - Designed to meet the needs of today’s Precision Rifle Series competitor, the MIL-C™ reticle allows for fast and accurate shots on target. 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.
 
"I just got this scope and I'm impressed. The magnification range packed into this smaller scope is awesome. The glass seems to be a lot better than my old NXS and my SHV. I really like how the illumination is on the side focus. Time will tell but generally NF stuff is top of the line. Looking forward to taking it to the range." Nick Chitwood.
 
"I found the eye-box to be much better than I thought possible on a 30mm maintube, tight but perfect on my MPA competition chasis. Pictures snap into place with beautiful and crisp reticle. It's a mini miracle IMO. I didn't expect so much from a small main tube. Way to go. Also, I like the relatively short field of view as I find it keeps me fine tuning my paralax as I should be doing. Another positive, I don't need to mess with my eye piece. It stays nice and true through magnifications and it locks." Donald.
