Trijicon RM55 45° RMR/SRO Offset Rail Adapter

Designed to pair a magnified optic with a Trijicon RMR(R) or SRO(TM) red dot sight in close-quarters situations, this adapter mounts to a Picatinny rail and provides a short rail at a 45° offset for fast optic transitions. Its low-profile aluminum construction lets it sit beneath many riflescopes without removing rings, and it can be mounted in front of or behind optics such as ACOG(R) or VCOG(R). Note: this listing is for the offset rail adapter only; the Trijicon RM33 Low Mount is required to attach an RMR or SRO sight.
