If you need something compact yet powerful, the ATACR 4-16x 42mm F1 delivers. The fully multi-coated ED glass lenses within are stunning. Adjustments are standard with the Nightforce low profile ZeroHold feature and are in 1/10 Mrad (12 Mils 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, first focal plane, reticles that provide for fast hold-off adjustments and precise ranging calculations. The ATACR 4-16x 42mm F1 sets the standard in mid-powered optics.
