The ATACR™ 5-25x56 “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*.
