The OSight SE MOS (brand part no. SE-MOS) is a fully enclosed pistol red dot built to the RMSc footprint, giving shooters a direct-mount optic for slides milled to that pattern. OSight houses a multi-reticle system in a CNC-machined enclosed body, offering a 2 MOA dot, a 32 MOA circle, or both together. A side-loading CR1632 battery tray allows changes without removing the optic from the slide, and battery life reaches up to 140,000 hours on the dot-only setting across ten brightness levels, including two dedicated night-vision settings. Among red dot sights, the SE MOS favors carry pistol shooters who want an enclosed-emitter optic on the RMSc footprint.
