Sig Sauer Romeo-X Compact 2 MOA Red Circle Dot FDE Open Reflex Sight

The Sig Sauer Romeo-X Compact is a pistol-mounted open reflex sight built around a rugged 7075 aluminum housing and finished in Flat Dark Earth. Purpose-built for everyday carry and tactical use, it ships with a selectable Circle Dot reticle that pairs a crisp 2 MOA center dot with a surrounding 32 MOA circle, giving the shooter fast target acquisition at close range and refined precision on smaller targets. The reticle can be run as dot-only, circle-only, or both, depending on the situation.

The Romeo-X Compact uses Sig Sauer's compact footprint and is factory-cut to co-witness directly on the Sig P365 slide, making it a natural pairing for optics-ready concealed-carry and duty pistols. A side-loading CR1632 battery compartment allows the battery to be swapped without removing the optic or losing zero, and the efficient LED combined with MOTAC motion-activated illumination delivers up to 20,000 hours of runtime. Brightness is controlled across 15 illumination settings so the dot stays visible in anything from bright daylight to low-light carry. Windage and elevation are tuned across a generous 80 MOA of adjustment range to make zeroing straightforward across a wide variety of pistol platforms.

Engineered as a military-grade reflex optic, the Romeo-X Compact pairs a low-profile deck with a clear glass window for an unobstructed sight picture, and its lightweight 7075 aluminum construction keeps carried weight to a minimum without sacrificing durability.
