The Osight S Rechargeable Reflex Sight is a fully enclosed reflex sight featuring the world's first Magnetic Charging Cover so it's always ready to go when you are. The Osight S provides up to 21,900 hours of runtime at level 3 (dot only) and up to 87,600 hours total runtime with the Magnetic Charging Cover at full charge, giving you enough juice to always be ready for action. The cover reveals real-time battery levels for both the optic and the cover itself, and it can easily be recharged via the included USB-C charging cable. The Osight S Reflex Sight is made from a proprietary OAL aluminum alloy that's nearly as light as 7075 aluminum but far stronger. The OAL material, combined with the enclosed design, keeps the Osight S operating in extreme conditions. The unit also features an aspherical glass lens that's ultra-clear and free of distortion. The reticle system comprises a 2 MOA dot and 32 MOA circle that can be used independently or together to provide the ideal aiming solution for your mission.
