Description Designed to deliver advanced optic performance, the Sightmark Ultra Shot A-Spec and R-Spec Reflex Sights provide repeatable accuracy and ultra-fast target acquisition across recreational, professional, and competitive shooting environments. Both optics feature premium wide-angle lens systems with scratch-resistant, anti-reflective coatings for a crisp, robust field of view, along with parallax correction (beyond 10–25 yards) and unlimited eye relief for reliable performance—even when perfect sight alignment isn’t possible. Each sight offers 4 illuminated reticle options with 10 brightness settings (A-Spec: red; R-Spec: red/green), paired with 1 MOA windage and elevation adjustments and up to 120 MOA of travel for precise, repeatable accuracy. Built tough, both models are shockproof, IP55 weather-resistant, recoil rated up to .50 BMG, and constructed from rugged, lightweight 6061-T6 aluminum with a protective shield. Powered by a single CR123A battery, the Ultra Shot series delivers 200–2,000 hours of battery life and features a low battery indicator, digital switch controls, and a 1-hour auto shut-off. The Interlock internal locking adjustment system ensures your zero stays locked in, while the quick-detach Picatinny mount allows for fast and secure installation. The Ultra Shot A-Spec is also fully compatible with the Sightmark XT-3 Tactical Magnifier (SM19062), expanding versatility for extended range applications. Includes adjustment tools, CR123A battery, operation manual, neoprene cover, and is backed by Sightmark’s Lifetime Warranty. U.S. Pat. D872219, D872219S1
