Trijicon MRO SD Features The Trijicon MRO SD maintains the same compact footprint as the original MRO while improving optical performance through a reengineered 25mm objective lens and advanced lens coatings. The result is a refined crisp 2 MOA green dot that stays sharp and easy to pick up quickly whether engaging close targets or working at distance with the optional 3x magnifier. Windage and elevation adjusters click in 1/2 MOA increments across 70 MOA of total travel and Trijicon upgraded these adjusters specifically to maintain stricter zero retention under drop and recoil. Eight brightness settings controlled ambidextrously let the shooter dial in the dot for anything from a dim indoor range to bright daylight. Housed in a forged 7075-T6 aluminum body that is hard anodized in Coyote Brown the MRO SD is fully sealed and rated waterproof to 100 feet standing up to hard use in the field or on duty. A single CR2032 battery powers the sight for up to 3 years of continuous use at a typical daytime setting keeping maintenance minimal between battery changes. At just 4.8 ounces and a 2.9 by 1.7 by 2.1 inch footprint the sight adds negligible weight or bulk to a carbine or shotgun. Shipping with no mount included the Trijicon MRO SD gives shooters the flexibility to choose the mounting height and footprint that best suits their platform.
