Trijicon MRO SD Features The Trijicon MRO SD builds on the original MRO footprint and durability with an enhanced optical design centered on a reengineered 25mm objective lens and advanced lens coatings. That lens delivers a refined crisp 2 MOA dot and the large aperture combined with a tapered light path maximizes the viewing area for better situational awareness during fast target engagement. The sight is optimized for pairing with the optional MRO 3x Magnifier giving shooters a path to extend the MRO SD s effective range without swapping optics. Ambidextrous brightness controls and sub-flush adjusters keep the controls accessible and snag-free whether the operator is right or left handed. Housed in a fully sealed waterproof hard anodized forged 7075-T6 aluminum body rated to 100 feet of submersion the MRO SD is built to survive the drops impacts and weather exposure that duty and field use demand. Upgraded windage and elevation adjusters maintain stricter zero retention under direct impact and heavy recoil a meaningful improvement for shooters running the sight on hard-recoiling carbines or shotguns. The sight runs on a single CR2032 battery with eight illumination settings and up to three years of continuous battery life at a moderate daytime setting minimizing the chance of a dead battery at an inopportune moment. With a lower one third co-witness mount included the Trijicon MRO SD is a complete ready-to-mount reflex sight package for sale at GrabAGun.
