The Geissele Lower 1/3 Co-Witness MRO Mount, Desert Dirt Color (Geissele part no. 05-470S) is a low-profile mount from Geissele Automatics built specifically for the Trijicon MRO footprint, sized so the dot sets the dot in the bottom third of the window for a lower one-third co-witness with the rifle’s flip-up iron sights. Finished in Desert Dirt Color, it’s built for a duty or competition AR that runs an MRO alongside backup iron sights and needs a consistent, repeatable optic-to-iron relationship.

Key Specifications
