The Olight Osight is getting a lot of attention and reviews. Survival Gear got one to give his take on this first optic offering from Olight... "Courting the attention of competitive shooters, Olight recently launched a new red and green dot for pistols called the Osight. A few optics companies already offer 'big window' dot sights, but Olight’s new model is getting much attention not only for its price, but also for the amount of features it offers. And yes, it’s rechargeable. The sight comes with a magnetic charging cover featuring a display that reveals the precise battery levels for both the cover and the optic. Osight says it should give you over 70,000 hours of use on the lowest brightness setting. The magnetic charging cover contains an additional 800-mAh battery to keep it topped off. What really struck me about Olight’s Osight was the extremely generous window and clarity when looking through it. The 0.94 x 0.85-inch objective lens provides a huge window size compared to many other reflex optics without feeling like you have a massive fixture on your rail."
