Cross Armory CRRMADAPTER Adapter Plate, Black Oxide

The Cross Armory CRRMADAPTER is an optic adapter plate designed to let pistol slides with an RMSC cut accept RMR-footprint optics. It is CNC machined from aerospace-grade aluminum and finished in a black oxide coating. The plate installs on RMSC cut slides without a thread post and includes hardware with pre-applied Loctite for installation.
