SIG SAUER | Romeo-X Enclosed Pro | Black

The ROMEO‑X Enclosed Pro is SIG SAUER's fully enclosed pistol red dot, built around the same sealed‑housing approach pioneered on the MIL‑SPEC ROMEO‑M17. A 7075 aluminum housing and aspherical lens keep the dot distortion‑free, and the enclosed design means no exposed emitter to get knocked out of alignment or fouled by debris -⁠- a real advantage for a carry or duty gun over an open‑emitter reflex sight. The side‑load battery is rated for roughly 20,000 hours of runtime, and the low deck height still co‑witnesses with standard‑height iron sights.
