Osight S Red Dot Sight by OLIGHT

Osight S is a revolutionary compact red dot sight with a magnetic charging cover that not only protects the optic but also features a built-in display showing battery status. The smart cover can recharge the optic up to 3 times and itself charges via USB-C. The sight has an internal battery with up to 21,900 hours of runtime (dot only, level 3 brightness) and supports magnetic recharging. The closed emitter system and parallax-free aspherical lens deliver exceptional clarity and fast target acquisition. You can switch between a 2 MOA dot, 32 MOA circle, or both, making it ideal for duty, tactical training, or night patrols. It mounts via the universal RMSc footprint, fitting pistols with optics-ready slides (like MOS or OR variants). The rugged OAL™ aluminum body ensures light weight and high strength with a hard anodized finish. It’s tested to retain zero even after 100,000+ rounds fired.
