Quantity in Stock: Osight SE Enclosed Emitter Optic — Simple Yet Extraordinary
The Osight SE takes the concept of a compact red dot to the next level. Designed for concealed carry, home defense, and professional duty use, this enclosed emitter optic blends precision engineering with everyday reliability. Its rugged 7075 aluminum housing and aspherical lens deliver a distortion-free sight picture, while the side-load CR1620 battery allows easy replacement without losing zero. Built on the RMSc footprint, the Osight SE mounts directly to most optics-ready slides and co-witnesses cleanly with factory sights.
