The SIG SAUER ROMEO-X is a rugged, enclosed-emitter red dot sight designed for concealed carry and personal defense applications. Built around a CNC 7075 aluminum housing with a fully sealed optical system, this red dot delivers durable performance in demanding conditions.

Featuring a high-efficiency point source emitter and distortion-free aspherical lens, the ROMEO-X provides a crisp 3 MOA red dot with 15 illumination settings, including three dedicated night vision modes. MOTAC (Motion Activated Illumination) technology automatically powers the reticle on when motion is detected to preserve battery life.

The side-mounted CR1632 battery compartment enables quick battery changes without removing the optic from the weapon. With up to 20,000 hours of runtime at medium settings, the ROMEO-X offers long-lasting reliability. Its low deck height allows for seamless co-witness with standard-height iron sights.
