The Osight S boasts a pioneering Magnetic Charging Cover with a battery display that shows real-time battery levels for both the cover and the optic, eliminating uncertainty. Designed with a fully sealed system, the optic offers unmatched protection against environmental elements. Its aspherical lens ensures zero distortion and parallax-free performance, delivering exceptional clarity through the large window for rapid, precise target acquisition. Switching between dot-and-circle, dot-only, or circle-only reticles lets you tailor your aiming solution to any scenario. The sharp, bright dot-and-circle reticle provides a cutting-edge aiming experience. The OAL housing is tough, strong, and nearly as lightweight as 7075 aluminum, with a Level III anodized finish that provides superior impact and corrosion resistance for lasting durability. Osight models have been field-tested with over 100,000 rounds, maintaining reliability and holding zero throughout.
