Geissele Spr Prn Mro 1/3 Co-wit Ddc

The Geissele Super Precision MRO 1/3 Co-Witness Mount is a precision-machined red dot optic mount engineered specifically for the Trijicon MRO and compatible 1x magnification sights. Machined from a single piece of 7075-T6 aluminum, this mount delivers the rigidity and repeatability demanded by operators, law enforcement, and competitive shooters who require absolute zero retention and rapid target acquisition.

The mount features Geissele's refined nut-and-bolt clamping design, applying 1,400 pounds of clamping force to lock your optic in place without shift or drift. Three integral shear lugs provide multi-axis rigidity, ensuring the sight returns to zero after removal and reinstallation—critical for duty weapons and field-swapped optics. The 1/3 co-witness height positions the MRO's optical axis 1/3 of the way down your rifle's iron sights, allowing iron sight use as a backup aiming reference while maintaining the red dot as primary aim point. This dual-sighting capability is preferred by tactical professionals who demand redundancy in dynamic or uncertain lighting conditions.

This mount is purpose-built for AR-platform rifles, carbines, and intermediate-length builds where a low-profile, high-strength optic mount is non-negotiable. Weighing only 0.19 lbs, it adds minimal mass while maintaining the structural integrity required for duty use, competition, or precision training. The compact 4.25 x 1.5 x 5.5-inch footprint integrates seamlessly with standard rail systems, leaving clearance for backup sights, magnifiers, and forward-mounted accessories.
