Trijicon MRO SD Patrol Features The Trijicon MRO SD Patrol centers on a 2 MOA red dot surrounded by a 68 MOA segmented circle a reticle pairing that gives shooters a precise aiming point for distance work along with the wide fast reference the circle offers for close engagements. Adjustment runs 1/2 MOA per click across a generous 70 MOA of total travel in both windage and elevation so the sight can be zeroed accurately and holds that zero under recoil. Five daylight brightness settings plus two night vision compatible settings and one super bright setting let the dot stay visible from bright sun to low light without washing out the shooter s view. A CR2032 battery delivers roughly three years of continuous runtime keeping the sight ready without frequent battery changes. Machined from forged 7075-T6 aluminum and hard anodized the MRO SD Patrol housing is fully sealed and waterproof standing up to the drops weather and rough handling that patrol and duty use brings. The full co-witness mount ships included aligning the dot with iron sights for a fast backup aiming option if the optic ever fails. Lens covers protect both the ocular and objective lenses when not in use and the included KILLFLASH anti-reflective device cuts glare and reduces the sight s visual signature in bright conditions. At 4.35 inches overall and 5 ounces with battery this compact rugged reflex sight suits duty carbines and shotguns alike for sale at GrabAGun.
