Geissele Super Precision MRO 1/3 Co-Witness Mount Black
The Geissele Super Precision MRO 1/3 Co-Witness Mount delivers competition-grade precision and rock-solid reliability for shooters who demand absolute confidence from their Trijicon MRO setup. Machined as a single unit from aerospace-grade aluminum, this mount is built to perform in the most demanding conditions.
- Precision machined from a single piece of 7075-T6 high-strength aluminum
- Generates over 1,400 lbs of clamping force for a bombproof hold
- Three shear lugs provide maximum rigidity and repeatable return to zero
- 1/3 co-witness height aligns perfectly with standard AR-15 iron sights
- Geissele's updated nut-and-bolt clamping system ensures consistent torque
- Designed specifically for the Trijicon MRO and similar red dot optics
Who This Is For
This mount is ideal for AR-15 and MSR platform shooters who run the Trijicon MRO as their primary optic and want absolute confidence in their zero — whether they're competing in 3-gun matches, running a duty rifle, or building a precision home-defense carbine. The 1/3 co-witness configuration keeps iron sights accessible in the lower third of the optic window without cluttering your field of view, making it a favorite among serious tactical and competition shooters alike.

Frequently Asked Questions
What is the difference between 1/3 co-witness and absolute co-witness?
A 1/3 co-witness mount positions your iron sights in the lower third of the optic's field of view, keeping most of the glass clear for a cleaner sight picture while still allowing quick access to backup iron sights. An absolute co-witness aligns the iron sights directly through the center of the optic window. The 1/3 co-witness configuration offered by this Geissele mount is preferred by many tactical and competition shooters for its unobstructed view downrange.
Will this mount work with red dot optics other than the Trijicon MRO?
This mount is engineered specifically to fit the Trijicon MRO footprint and mounting pattern. While it may appear similar to other mounts, Geissele designs each Super Precision mount to match exact optic dimensions for a precise, wobble-free fit. If you're running a different optic such as an Aimpoint T2 or Holosun, Geissele offers dedicated Super Precision mounts for those platforms as well — be sure to select the correct model for your optic.
How does the Geissele Super Precision mount maintain return to zero?
Geissele's Super Precision mount uses three integrated shear lugs that mechanically index against the Picatinny rail, preventing any lateral or rotational movement under recoil. Combined with over 1,400 lbs of clamping force generated by the updated nut-and-bolt system, the mount locks down with exceptional consistency. This design ensures that if you remove and reinstall the mount, your zero will remain reliable — a critical feature for professional users who field-strip or transition equipment regularly.
