SIG Sauer Electro-Optics ROMEO1 1x30mm Mini Reflex Red Dot Sight
The SIG Sauer Electro-Optics ROMEO1 is a compact open reflex red dot built around a molded glass aspheric lens for high light transmission and a clear, distortion-free sight picture. Push-button illumination control and MOTAC (Motion Activated Illumination System) provide instant-on operation with automatic shutoff for power management.
Designed with a lightweight CNC magnesium housing and sealed for waterproof (IPX-7) and fogproof performance, the ROMEO1 uses a bottom-loading CR1632 battery accessed from the underside; battery replacement typically requires removing the optic from the slide/mount.
