Trijicon MRO SD Features The Trijicon MRO SD builds on the original MRO footprint and durability while adding a reengineered objective lens and advanced lens coatings that deliver a crisp refined 2.0 MOA green center dot. That reticle is optimized to pair cleanly with the optional MRO 3x magnifier giving shooters a path to extend the sight s capability without replacing it outright. Upgraded windage and elevation adjusters moving in half MOA clicks across 70 MOA of total travel are engineered to maintain a tighter zero under the repeated impact and recoil that duty and competition use demand. Ambidextrous brightness controls and sub-flush adjusters round out a design meant to be adjusted quickly without snagging on gear or interrupting a shooter s grip. The housing is forged from 7075-T6 aluminum and hard anodized in Coyote Brown then fully sealed to a 100 foot waterproof rating so the sight can handle submersion rain or heavy field use without hesitation. Eight brightness settings including configurations optimized for both daylight and night vision devices are run off a single CR2032 battery rated for roughly three years of continuous use at a mid-range daytime setting. At just 4.8 ounces and a compact 2.9 by 1.7 by 2.1 inch footprint the MRO SD stays light on a rifle or shotgun without adding bulk to the sight picture. The Trijicon MRO SD ships complete with its full co-witness mount installed making it a ready-to-run reflex sight for sale at GrabAGun for duty carbines home defense shotguns and competition rifles alike.
