The Trijicon MRO SD Patrol is a sealed, miniature reflex sight intended for use on rifles, carbines, and shotguns to provide fast target acquisition. The MRO SD maintains the same durability and footprint of the original MRO with an enhanced optical design for pairing with magnifiers and night vision devices. The sight features a reengineered objective lens with advanced lens coatings that delivers a refined, crisp 2.0 MOA center dot, optimized for seamless use with the optional MRO 3x Magnifier.
The MRO SD is equipped with upgraded windage and elevation adjusters for improved zero retention under direct impact and heavy recoil, ambidextrous brightness controls, and a fully sealed, waterproof, hard-anodized forged 7075-T6 housing. The MRO SD Patrol comes equipped with lens covers for both the ocular and objective lenses, along with an Anti-Reflection Device KILLFLASH® that protects you from unwanted detection or in bright conditions while eliminating glare. The larger viewing area allows for faster acquisition and engagement with reduced “tube effect,” and the brightness dial is equally usable by left- or right-handed operators without having to remove hand from fire control, with 8 brightness settings including 2 night vision-compatible settings.
The capless design utilizing sub-flush adjusters eliminates lost caps, snag hazards and ensures against inadvertent adjustment or loss of zero. This no-mount configuration is in stock for USA purchase and export to Canada through Arms East.
