Steel Chassis / Polymer Housing

Skeletonized steel chassis molded into high-strength polymer housing (ROMEO-RS = Reinforced Steel). The steel chassis supports and protects the aspherical glass lens while the polymer housing reduces overall weight. Threaded metal inserts at mount points, battery tray, and adjustment mechanisms maintain long-term accuracy and durability.

Shield RMSc Footprint with Steel Recoil Pins

Updated SIG footprint maintains true RMSc compatibility while adding steel recoil pins for lateral shift prevention. Threaded metal inserts allow optimal torque load when mounting to pistol slide.

3 MOA Red Dot

3 MOA red dot reticle with high-efficiency point source LED. 8 individual brightness settings for varied lighting environments.

Aspherical Glass Lens

Premium molded aspherical glass lens provides distortion-free sight picture across the full lens surface.

MOTAC

Motion Activated Illumination powers up when motion detected and powers down when inactive. Preserves battery life during periods of inactivity.

Side-Load CR1632 Battery

Side-mounted CR1632 battery tray with security screw provides battery access without removing optic from slide. 20,000-hour minimum runtime at medium brightness dot-only setting.

70 MOA Adjustment Range

70 MOA total elevation and 70 MOA total windage travel. Large side control button for quick brightness adjustments embedded into housing to prevent accidental actuation.
