Trijicon MRO SD 1x25 Red Dot Sight w/ 2.0 MOA Adjustable Red Dot; Lower 1/3 Co-witness Mount (AC32069) MRO-C-2200303

Shooters who run suppressors on their rifles know that standard mount heights create co-witness problems - and the Trijicon MRO SD MRO-C-2200303 with lower 1/3 co-witness mount solves that problem directly. The SD height corrects the geometric relationship between the red dot and backup iron sights on suppressed builds, and the lower 1/3 co-witness mount position keeps that backup iron sight reference in the lower portion of the sight window, where it provides a useful backup without cluttering the primary sight picture during normal red dot use.

The lower 1/3 mount position is a deliberate preference for many serious rifle shooters — backup iron sights that appear in the lower third of the Trijicon MRO red dot window are visible and accessible when needed without dominating the field of view during primary optic use. For shooters who find full co-witness distracting, the lower 1/3 position is immediately more comfortable and natural across a full day of shooting.

The Trijicon MRO's slightly canted objective lens design reduces the overall optic length while maintaining the large aperture that eliminates the tunnel effect compact red dots create. The result is a sight that occupies less rail space than its sight-picture quality would suggest, maximizing platform space while delivering a wide, open field of view that faster target acquisition demands.

The red dot reflex sight MRO-C-2200303 capless sub-flush adjusters maintain strict zero retention without caps being lost. Ambidextrous brightness controls work naturally for both-handed shooters. The Trijicon MRO mount forged 7075-T6 housing is fully sealed and waterproof to 100 feet.
