NIGHTFORCE, C577, ATACR - 5-25x56mm F1 - ZeroStop - .1 Mil-Radian - DigIllum- PTL - H59

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.

The H59 reticle is a "field-tuned" version of our H58 reticle. A widened horizontal grid by one mil for increased wind holdover. And the center cross has been turned into a "broken cross" so groupings are less obscured and more easily seen. Illumination now standard.
