The Trijicon RMRcc footprint quick-release lower 1/3 Co-witness mount with Trijicon Q-LOC technology is constructed from rugged Mil-Spec 6061-T6 aluminum, featuring an Easy-to-use, one-handed, tool-less mounting system. This mount ensures reliable return-to-zero performance and boasts a lightweight, low-profile design compatible with any picatinny rail setup. Specifically designed for the Trijicon RMRcc, it provides a lightweight Lower 1/3 Co-Witness mount option for attaching a Trijicon red-dot sight using the RMRcc footprint to any rifle equipped with a picatinny rail. The AC32111 configuration offers a Lower 1/3 Co-Witness with backup iron sights, positioning the RMRcc higher than the iron sights for an unobstructed view through the optic. The iron sights remain visible in the lower 1/3 of the optical window, ready for use as a backup aiming solution.
