The SIG SAUER ROMEO-X Enclosed is a sealed-emitter pistol red dot built for duty and everyday carry. The fully enclosed emitter keeps lint, dust, rain, and snow out of the optical path so your dot stays clear when it matters.

Key Features

• 3 MOA red dot — crisp dot balancing speed and precision
• Fully enclosed, sealed 7075 aluminum emitter for maximum reliability in adverse conditions
• MOTAC (Motion Activated Illumination) wakes the dot on movement and sleeps it at rest — up to 20,000 hours of runtime
• Side-loading CR1632 battery tray — swap the battery without removing the optic or losing zero
• 15 daylight-bright illumination settings with a distortion-free aspherical lens
• Low deck height supports iron-sight co-witness; waterproof and shock-resistant
