Are the Trijicon RMRcc and Shield RMSc compatible?
Not cross-compatible. The Trijicon RMRcc and Shield RMSc are distinct footprints — an optic built for one won’t sit on a slide cut for the other without a dedicated adapter plate (where one exists). Buy the optic that matches your slide’s cut, or a plate that converts it.
