Olight Osight RMR to RMSc Adapter Plate

Olight Osight RMR to RMSc Adapter Plate

The Olight Osight RMR to RMSc Adapter Plate allows shooters to mount RMSc-footprint optics onto slides originally cut for the larger RMR pattern. Designed for direct conversion, this adapter plate creates new flexibility for compact red dots without requiring a new slide or aftermarket milling. It’s a practical solution for anyone who wants to run an enclosed emitter or RMSc-pattern optic on an RMR-cut host.

Each plate is precision-machined from SUS420 stainless steel and treated with a matte black PVD finish for corrosion resistance and long-term durability. The material and finish ensure it resists wear, even under frequent removal or sustained use in harsh environments. The fit is secure, maintaining optic alignment and zero during live fire with proper torque and thread engagement.

Compatibility includes Olight Osight optics such as the SE, S, and other RMSc or “K” footprint designs including the 407K, 507K, and EPS Carry. The adapter installs quickly and includes all required mounting screws and a dedicated installation tool to simplify setup. The RMR to RMSc Adapter Plate aligns tightly to the slide while presenting a minimal profile and low additional weight.

At just 14 grams, with approximate dimensions of 45.2 mm × 25.5 mm × 4.3 mm, the plate adds negligible mass to the slide. The slim profile preserves standard sight height and co-witnessing potential while still offering full mechanical strength. The steel construction ensures that the adapter can withstand the recoil forces of centerfire handgun calibers without flex or distortion.

In the box you’ll find the RMR to RMSc Adapter Plate, the appropriate mounting screws, and a torque-compatible installation tool. Whether you’re retrofitting a carry pistol, modernizing a duty slide, or expanding optic compatibility across a fleet, the Olight Osight RMR to RMSc Adapter Plate delivers a secure and affordable path to run newer optics on legacy mounts.
