The ATACR™ 4-16 x 50 incorporates the same multi-coated ED glass, resulting in brilliant images, superb color contrast and outstanding low-light performance, as used in the original Nightforce ATACR™ 5-25 x 56—one of the most popular and acclaimed long-range riflescopes the company has ever built. The 4-16 x 50 version measures just 13.1 inches and weighs 33 ounces.
Every possible advancement is standard with the ATACR™ 4-16 x 50, including an integrated Power Throw Lever, low-profile ZeroStop™ elevation technology, DigIllum™ digital reticle illumination, faster diopter adjustment, and highly visible magnification markings. Side parallax adjustment is clearly marked with appropriate distances. The windage adjustment is capped to prevent accidental adjustments in the field.
