Cross Armory CRRMADAPTER RMSc to RMR Adapter Plate Black Oxide Aluminum

The Cross Armory CRRMADAPTER is a precision RMSc to RMR optic adapter plate that lets you mount any RMR-pattern red dot sight on a pistol slide originally cut for the smaller RMSc footprint. If you already own an RMR-footprint optic, this plate opens that optic up to a much wider range of host pistols without having to machine a new slide or send the firearm off to a gunsmith.

The plate is machined from aluminum and finished in a low-profile black oxide coating that blends in with most factory and aftermarket slide finishes. Its low-rise design keeps the optic sitting close to the slide for a clean sight picture and a natural co-witness with the pistol's factory iron sights.

Installation is straightforward: the adapter drops onto the existing RMSc optic-cut slide using the slide's factory mounting holes and screws, then accepts any standard RMR-footprint reflex sight on top. The plate is designed for slides with a flat mounting surface in the RMSc pocket and provides a secure, repeatable mounting platform for everyday carry, range, and competition use. Compatible with optics from Trijicon, Holosun, and other RMR-footprint manufacturers.
