Without a doubt, this could be called the perfect all-around long range riflescope.

The ATACR 5-25x56 F1 is packed full of features that might make some grown men cry. The ED optics are beautiful, the mechanics sound. The adjustments are standard with the patented Nightforce Hi-Speed ZeroStop, and 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.

All of these features are paired with intelligent, Nightforce F1 reticles to set a new standard in long range shooting. If there's something this riflescope can't do, we have yet to find it.

Tenebraex Flip Covers are now included with ATACR™ riflescopes*.
