The Olight Osight SE is a compact, enclosed-emitter green-dot optic built for reliability, clarity, and fast performance on today's optics-ready handguns. Its 6 MOA green dot delivers rapid target acquisition with excellent daylight visibility, making it ideal for concealed carry, home defense, and duty applications. The fully enclosed emitter ensures consistent performance by protecting the lens from rain, dust, and debris, while the aspherical lens provides a distortion-free, parallax-free sight picture for precise shooting. A side-loading CR1620 battery allows quick replacement without removing the optic or losing zero, supporting an impressive 75,000-hour runtime. With its slim, durable aluminum alloy housing, RMSc footprint, multi-coated objective lens, and IPX7 waterproof rating, the Osight SE mounts seamlessly to compact and micro-compact pistols. Lightweight at just 0.97 oz and equipped with side-button brightness controls (8 day / 2 night), it's a rugged, intuitive, and high-performance solution for everyday carry.
