The Trijicon MRO (Miniature Rifle Optic) is Trijicon's answer to the Aimpoint T2 and PRO, delivering an enclosed red dot with a massive 25mm objective lens that provides the largest sight picture in its class. Launched in 2015, the MRO was designed from the ground up as a rifle-dedicated optic, addressing complaints that the RMR's tiny window was too small for primary rifle use.
The MRO's fully enclosed housing protects the LED emitter from debris, rain, and environmental contamination while the 25mm lens creates a tunnel-free viewing experience with both eyes open. At 4.1 oz without mount, the MRO undercuts the Aimpoint T2 in weight while offering a larger objective lens and 5-year battery life on a single CR2032.
Available in both green and red dot variants, the MRO features 8 brightness settings including 2 night-vision-compatible levels. The ambidextrous brightness dial and capped turrets provide a clean, snag-free profile. While the MRO experienced minor parallax issues in early production runs, current models have been refined and perform well at all distances.
