Olight Osight consists of an optic and a charging cover. This is the industry’s first charging cover with a percentage battery display, allowing you to monitor the battery level of both the cover and optic anytime. In addition, you can also check the battery status with the tri-color indicator on the optic. Both the cover and the optic are powered by a rechargeable high-capacity battery. A fully charged cover can charge a low-battery optic three times. On a single charge, the optic itself can last over 70,000 hours in its lowest mode. Even at its brightest setting, it can continuously run for over 17 days and this duration can be extended to over 70 days with the support of a fully charged charging cover. The cover is USB-C rechargeable, while the optic is charged magnetically. Featuring a 0.94 x 0.85 in lens, the optic ensures accurate target acquisition even during recoil. The 3 MOA dot is clear and easy to locate, ensuring swift and precise dot acquisition. The optic can be easily zeroed with windage and elevation adjustments. And it has successfully maintained zero during a 10,000-round test. It features manual mode, lockout mode, and auto-sensing mode. With its motion sensor function, you can wake the optic in an instant, and it will turn off automatically after 10 minutes of inactivity. It adopts industry standard mounting footprint for optic cuts. The Osight is a reliable and versatile optic designed for training, performing well in competitions as well.
