Nightforce Optics ATACR 5-25x56 F2 Riflescope

The ATACR 5-2556 Enhanced Riflescope includes the Nightforce Hi-Speed adjustments with patented ZeroStop, and is available in .1 Mrad (12 Mils per revolution) or .25 MOA (30 MOA per revolution) increments. A capped windage adjustment helps prevent accidental adjustment in the field. The parallax adjustment is marked with approximate numbered distances and is coupled with DigIllum digital reticle illumination. The eyepiece features enhanced engraving, an integrated Power Throw Lever (PTL) and an XtremeSpeed thread for making a fast diopter adjustment.

The 34mm tube allows 120 MOA/34.9 Mils of elevation adjustment. Fully multi-coated ED glass results in light transmission values of over 90%, brilliant images and exceptional color contrast. A magnification range of 5x to 25x, and a wider field of view as a result of its unique optical prescription (17.96 feet at 5x) will cover virtually any situation a shooter could encounter.

Tenebraex Flip Covers are now included with ATACR riflescopes*.

  Range estimation
  
  The Nightforce MIL-R reticle can provide you with an accurate distance to your target, when the size of the target is known, by utilizing one of 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-T
  Our new MOAR-T delivers. .0625 MOA lines, with 1 MOA elevation and windage markings. Allows accurate rangefinding and holdover estimation at the longest distances. Center Illumination only.
  
  The elevation and windage marks can be used for ranging objects when the size of the target is known. Bracket the target from top to bottom or side to side within the marks. Distance to target can then be determined using this formula:
  
  Target size in inches moa x 100 = range in yards.
  Please note that accurate rangefinding with the MOAR reticle can only be accomplished at the power settings shown above.
  
  
• MOAR 20 MOA
  Combined with a floating center crosshair, this makes for a reticle extremely fast and easy to use in the field. MOAR reticles in Nightforce 5.5-22x and 8-32x NXS models have a 20 MOA scale below centerline (at left). Reticles in 3.5-15x models have an additional 10 MOA scale below center.
  
  The elevation and windage marks can be used for ranging objects when the size of the target is known. Bracket the target from top to bottom or side to side within the marks. Distance to target can then be determined using this formula:
  
  Target size in inches Image size (moa) x 95.5 = range in yards.
  For field expedient ranging inside of 500 yards, a constant of 100 can be used in place of 95.5.
  
  Please note that accurate rangefinding with the MOAR reticle can only be accomplished at the power settings shown above.
