Trijicon 2200331 Mro Sd Black 1X25Mm 2 Moa Green Dot Low Mount

The Trijicon MRO SD is a compact 1x25mm red dot sight built for shooters who demand speed and durability without compromise. Designed for rifles, carbines, and shotguns, this sealed reflex optic delivers the same rugged performance as the original MRO in a form factor that won't bulk up your platform or slow your target acquisition. The SD variant brings an optical upgrade specifically engineered to work seamlessly with magnifiers and night vision devices—a huge advantage if you're building a versatile duty, hunting, or tactical setup.

What sets the MRO SD apart is its reengineered objective lens with advanced coatings that produce a crisp, clean 2.0 MOA green dot reticle. That tight center dot cuts through ambient light and gives you a precise aiming point whether you're shooting at 7 yards or 700. The housing is forged 7075-T6 aluminum with matte black hard-anodize—the same material and finish you'll find on quality AR platforms. It's waterproof to 100 feet, so creek crossings, heavy rain, or accidental dunks won't kill your zero.

The controls are intuitive: ambidextrous brightness knobs let you dial in the dot without removing your hands from the gun, and there are eight illumination settings to handle everything from bright daylight to low light. A single CR2032 battery runs the sight for three continuous years at day setting 3, so you're not constantly hunting for spares. Windage and elevation adjusters lock in your zero and hold it under heavy recoil—built for real rifles, not range queens.

At just 4.8 ounces and measuring 2.9 inches long, the MRO SD mounts low on your receiver without eating up rail space or creating unwanted height-over-bore. If you ever want to add magnification, the optional MRO 3x Magnifier pairs directly to the sight for extended-range work. Whether you're setting up a lightweight carbine, a dedicated hunting rifle, or a duty gun, the MRO SD gives you a rock-solid foundation.
