OSight S Red Dot | 2 MOA Dot & 32 MOA Circle

The OSight S is a compact RMSc‑footprint reflex sight that pairs a 2 MOA aiming dot with a 32 MOA circle reticle for fast, intuitive sighting. It uses a rechargeable lithium‑ion power system with a magnetic USB‑C charging cover and a sealed housing designed to resist the elements. The sight employs an aspherical, parallax‑free lens and offers multiple reticle configurations and brightness settings for a range of lighting conditions.

Common applications include everyday carry (EDC) on compatible pistols and competition or range use where rapid target acquisition and a clear sight picture matter. The optic’s lightweight design and RMSc compatibility make it suitable for compact pistols and slide‑mounted use.
