OSight Osight S Features The OSight Osight S is built as a fully sealed enclosed emitter optic a design that offers unmatched protection against dust moisture and debris compared to an open emitter red dot sight. An aspherical lens ensures zero distortion and parallax-free performance delivering exceptional clarity through a large viewing window for rapid precise target acquisition at any distance. The multi-reticle system lets the shooter switch between a 2 MOA dot for precision work a 32 MOA circle for fast close-range acquisition or the combined dot-and-circle reticle depending on the shooting scenario at hand. This flexibility means a single optic can serve both a precision rifle role and a close-quarters carbine role without swapping sights. A pioneering magnetic charging cover includes its own battery display that shows real-time battery levels for both the cover and the optic itself removing the guesswork that comes with a standard battery compartment. The OAL housing is nearly as lightweight as 7075 aluminum while remaining tough and strong and a Level III anodized finish in Flat Dark Earth provides superior impact and corrosion resistance for lasting durability in the field. Built on the widely supported RMSc footprint the Osight S mounts to a broad range of pistol slides already cut for that pattern. OSight states its optics have been field-tested with over 100 000 rounds while maintaining reliability and holding zero throughout and the Osight S in Flat Dark Earth is available for sale at GrabAGun for shooters who demand that level of proven durability.
