OSight OSight SE Enclosed Red Dot Sight (RMSc) - 2 MOA Dot / 32 MOA Circle
The OSight SE is a compact enclosed-emitter pistol red dot built around an RMSc footprint for direct mounting on compatible optics-ready slides. It features an aspherical lens for a clear sight picture, a multi-reticle system (dot, circle, or dot-plus-circle), and a low-profile housing sized for carry guns.
Brightness is adjustable with 10 total settings (8 daylight and 2 night vision), with motion-sensing activation to help manage runtime. Power comes from a side-loading CR1620 battery so the optic can stay mounted during battery changes.
