The GBRS Group Lerna Mount in Black, built for the Trijicon MRO (GBRS Group part no. GEAR-LERN-MRO-BLK), raises your red dot to a 2.91 in optic centerline so gear like ear pro, comms headsets, gas masks, and night vision does not crowd out a usable sight picture. Standing your optic up to that height lets you run a more athletic, heads-up shooting stance while keeping your spine vertical, which pays off when you are wearing body armor or presenting plates toward a threat. That heads-up posture also speeds up target processing and situational awareness compared to hunching down to a lower-mounted optic. Machined from aluminum with a hard-anodized finish, this Lerna mount is fit specifically to the Trijicon MRO and finished in Black to match the rest of your build.
