The Nightforce Limited Production Run Mil-Spec ATACR 4-20x50mm F1 is an elite, contract-overrun precision riflescope system built to the exact specifications of USSOCOM's R-VPS (Rifle-Variable Power Scope) program. Featuring premium Extra-low Dispersion (ED) glass housed within a bulletproof 34mm main tube, this first-focal-plane (F1) optic offers a highly versatile 4-20x magnification range tailored for semi-automatic sniper and designated marksman systems. It comes factory-equipped with the highly advanced Horus Vision TREMOR3 reticle, which uses a grid-based system to facilitate rapid windage holds and elevation adjustments without requiring the shooter to turn the turrets. The special-edition R-VPS kit (identified by MPN JQ74-M642-1) is supplied as a complete mission solution, bundling a heavy-duty tan hardcoat anodized finish with a purpose-built Nightforce mount designed for integrated laser rangefinder platforms. Packing a massive 38 MRAD of internal elevation travel into a remarkably compact footprint, this mil-spec deployment kit is engineered to survive stringent military pressure and submersion testing while maximizing intermediate-range target engagement.
