Trijicon MRO HD 1×25 Red Dot Sight, 2 MOA Dot & 68 MOA Circle, Lower 1/3 Co-Witness Mount, Black
The Trijicon MRO HD lower 1/3 co-witness sight combines a black 1×25 optic with the AC32069 mount. Model MRO-C-2200053 retains the HD system’s selectable red 2 MOA dot and 68 MOA segmented circle. This package includes the sight and mount, without a magnifier.
This configuration uses a lower 1/3 co-witness mount that allows compatible iron sights to sit lower in the sight picture. That leaves more of the central window unobstructed than a full co-witness arrangement. The included AC32069 is a fixed mount, distinct from the Q-LOC quick-release mount supplied with the corresponding Patrol version.
The HD reticle is selectable: the center dot can appear on its own or with the surrounding segmented circle. The ambidextrous control combines reticle selection and brightness adjustment. There are 16 brightness settings in total, with eight for each reticle mode, including two night-vision-compatible settings per mode. These low-output settings support compatible night-vision equipment; the sight does not provide night vision by itself.
The MRO HD uses an objective lens designed for compatibility with a magnifier, while retaining a non-magnified 1x view on its own. A 25 mm objective provides a generous viewing window, and the sight has unlimited eye relief. A magnifier is a separate purchase, and its mount height must be compatible with the selected sight mount.
The sight uses a sealed, hard-anodized housing made from forged 7075-T6 aluminum. Sub-flush adjustment controls keep protrusions to a minimum, while multi-coated lenses support a clear view. The matte black finish is paired with red LED illumination.
A CR2032 battery powers the sight, and the tethered battery cap stays attached during battery changes. Trijicon rates continuous battery life at up to 2.5 years in dot-only mode or 75 days with the circle-and-dot reticle, measured at daylight setting 3 and 70 degrees Fahrenheit. Brightness, reticle choice, and temperature affect actual runtime.
