Nightforce ATACR 4-20x50mm F1 ZeroStop .250 MOA DigIllum PTL MOAR
The Nightforce ATACR 4-20x50mm F1 fills a crucial magnification gap in the ATACR lineup, offering a 5x zoom range in a compact, lightweight first focal plane configuration. This 34mm tube scope delivers impressive adjustment range (130 MOA elevation) and is equally at home on bolt action precision rifles or semi-automatic tactical platforms. The first focal plane design ensures consistent MOAR reticle subtension at any magnification, critical for rapid distance estimation and holdover calculations. With ZeroStop technology, DigIllum illumination, Power Throw Lever, and ED glass optics, the ATACR 4-20x50 F1 provides elite-level performance in a more compact package than its larger siblings.
