The Trijicon RMR Full Co-Witness Mount Quick Release features an aluminum design and a matte black anodized finish. It is easy to use with a one-handed, tool less mounting system. This lightweight low mount is perfect for mounting the Trijicon RMR on any weapon platform with a Picatinny rail. The RMR is mounted at the same height as the iron sights with the optic's aiming dot appearing at the top of the iron sight. This mount is typically used with flip up iron sights.
