The Trijicon RMR/SRO Lower 1/3 Co-Witness Mount with Q-LOC Technology (brand part no. AC32075) mounts an RMR or SRO higher than a rifle’s iron sights, giving a clearer field of view while keeping the irons visible in the lower third of the optical window as a backup. Machined from Mil-Spec drop test rated 7075-T6 aluminum, it uses the same one-handed, tool-less Q-LOC attachment system as Trijicon’s other quick-release mounts.
