Osight RMR to RMSc Adapter Plate

Osight RMR to RMSc Adapter Plate

Need to run a compact RMSc / “K” footprint red dot on a slide that’s cut for the larger RMR footprint? This RMR to RMSc Adapter Plate bridges the gap—letting you mount RMSc-pattern optics onto an RMR-cut slide without swapping slides or giving up future optics flexibility. Made from SUS420 stainless steel and finished in a matte black PVD coating, it’s a durable, wear-resistant solution for shooters who want more red dot options on an RMR platform.
