he SIG SAUER ROMEO-X® Enclosed Compact Red Dot Sight combines a fully enclosed optical system with rugged construction and a streamlined profile designed for concealed-carry applications. Compatible with the Shield RMSc footprint, this compact pistol optic is designed for the SIG SAUER P365 and other compatible optics-ready pistols.

Constructed with a precision-machined 7075 aluminum housing, the ROMEO-X Enclosed features a fully enclosed, sealed, and argon-purged optical system designed to protect the optic from environmental exposure. Its aspherical glass lens system is engineered to provide a clear, distortion-controlled sight picture, while the patent-pending beryllium copper flexure system supports the optic's durable construction.

The optic's ultra-low deck height allows for co-witnessing with compatible standard-height iron sights on properly configured platforms. A side-loading CR1632 battery compartment enables battery replacement without removing the optic from its mount, helping preserve the established zero.

The 3 MOA red circle-dot reticle offers a defined aiming point, supported by 15 illumination settings, including 12 daylight settings and 3 night-vision-compatible settings. SIG SAUER's MOTAC™ (Motion Activated Illumination) technology helps conserve battery power by activating illumination when motion is detected. The optic provides a listed runtime of up to 20,000 hours from one CR1632 battery.

Designed for demanding use, the ROMEO-X Enclosed features an IPX7 water-resistance rating and an adjustment range of 65 MOA elevation and 70 MOA windage. Measuring 1.62 inches long, 1.23 inches wide, and 0.94 inches high, it provides a compact footprint for compatible pistol configurations.

The SIG SAUER ROMEO-X Enclosed Compact combines an RMSc-compatible footprint, enclosed 7075 aluminum housing, side-loading battery, low-profile design, and motion-activated illumination in a compact red dot optic. Available body colors in the product family include Black and Flat Dark Earth (FDE); confirm the selected color configuration before ordering.
