The Sig Sauer ROMEO3 XL is an open reflex sight designed for use on MDR rifles, shotguns, and PDWs, the XL in its name refers to its extra large 35mm wide sight window that allows for rapid target engagement. The ROMEO3XL features a high transmittance red notch reflector that produces a crisp red dot. The ROMEO3 XL features Sig's MOTAC (Motion Activated Illumination System) that activates red dot illumination when motion is detected and deactivates dot illumination when motion ceases - allowing for thousands of hours between battery changes.

Great reflex sight. It is big, about the same window as a C-More Railway sight but not the length or weight. Using it on my S&W 41 PC pistol for rimfire steel challenge. Works very well so far.

Great optic. Large field of view. I own 2 of them on different styles of firearms. Mounted with ADM quick release mounts. Ordering and shipping was excellent as always. I will buy more as needed.
