Like New Nightforce ATACR 4-20x50 F1 ZeroStop .1 Mil-Radian DigIllum- PTL TReMoR3 C637

The ATACR 4-20x50mm family of riflescopes defines Rugged, Reliable, and Repeatable. They feature a one-piece tube precision machined from a solid bar stock of 6061-T6 aircraft-grade aluminum alloy. The tube is two to three times thicker than riflescopes of a lesser quality, resulting in less overall stress, greater thermal stability, a consistent zero and a virtually impervious shield for the precision optics within. The lenses are matched and aligned by hand in a process called optical indexing to ensure the highest possible optical performance. The objective lens utilizes a multi-element design like those found in the highest quality telescopes to focus light rays more precisely for exceptional image clarity and color accuracy. Optical performance is further enhanced thanks to multi-coated ED glass that results in superb light transmission, brilliant images, and exceptional color contrast. The elevation turret on the ATACR 4-20x50mm Riflescopes are equipped with Nightforce’s ZeroStop Technology to provide an instant return to zero after making adjustments in the field. After sighting in your rifle, simply set the ZeroStop to create a positive mechanical stopping point at your chosen zero point. Then, no matter how many elevation adjustments you make, turning the elevation knob down to the ZeroStop setting returns you to your original zero, completely by feel—even in total darkness or while wearing gloves. The internal mechanisms on the windage and elevation turrets are held in place by a specially designed spring that spends two weeks in a polishing tumbler before being installed in the optic to deliver perfectly smooth operation. This guarantees zero loss of integrity, zero loss of repeatability

They come equipped with multi-coated ED glass that results in superb light transmission, brilliant images, and exceptional color contrast. Featuring sophisticated reticles, these scopes leave nothing to chance. The ATACR from Nightforce redefines the \"long\" in long range, leaving the possibilities endless.
