Trijicon MRO SD Patrol Combo Features The Trijicon MRO SD Patrol Combo centers on a 2 MOA aiming dot inside a 68 MOA segmented circle giving the shooter both a precise point of aim and a fast wide reference ring for rapid target acquisition. Its large aperture and tapered light path maximize the viewing area for a sight this compact supporting the both eyes open shooting style that keeps situational awareness high in dynamic scenarios. A re-engineered objective lens on the SD version improves optical clarity over the original MRO while also enabling full compatibility with the included 3x magnifier. Windage and elevation adjusters have been upgraded to maintain stricter zero retention under drop and recoil a meaningful improvement for a sight meant to take hard use. Housed in a fully sealed hard anodized forged 7075-T6 aluminum body the MRO SD is built to survive submersion to 33 feet and resist the knocks of daily carry. Ambidextrous brightness controls span 8 total settings including day night vision compatible and super bright modes so the dot stays visible from bright daylight through low light conditions. The included 3x magnifier mounts on a quick release flip to side lever that swings out of the way instantly or flips over top of back up iron sights when not needed. Shipping on a full co-witness mount with lens covers an anti-reflection device mounting tools and a lens cloth the MRO SD Patrol Combo gives patrol and duty minded shooters a complete ready to mount optic system.
