The Olight Osight SE is a compact enclosed-emitter red dot sight built on the industry-standard RMSc footprint. It is designed for slimline, compact and subcompact pistols used for concealed carry, self-defense, home defense and sport shooting.
The multi-reticle system lets you switch between:
- 2 MOA Dot
- 2 MOA Dot + 32 MOA Circle
- 32 MOA Circle only
This gives you a fine aiming point for precision or a larger circle for fast target acquisition.
A side-loading CR1620 battery lets you replace the cell without removing the optic from the slide, so your zero stays intact. Runtime is up to 75,000 hours on Mode 3 (dot only). A motion sensor turns the optic off after inactivity and wakes it when movement is detected. A flashing reticle warns when the battery is low. Memory function remembers your last brightness setting.
The aspherical lens provides a clear, distortion-free view with true parallax-free performance. Window size is 21 × 14 mm. The housing is machined from 7075 aluminum with a hard-anodized finish and is rated IPX7 waterproof. Ultra-low deck height supports co-witness with most factory or suppressor-height iron sights. Adjustments are 1 MOA per click.
