The Super Precision MRO Series was developed specifically to work with the Trijicon MRO and like mounted red dot optics. These mounts are precision machined from a single piece of 7075-T6 high strength aluminum and are available in both co-witness and lower third co-witness options. Utilizing Geissele's update of the classic nut and bolt method, this mount will attach your red dot to your weapon with 1,400 pounds of clamping force, and features 3 shear lugs for maximum rigidity and return to zero.
