The Sig Sauer Romeo-X is a compact enclosed reflex sight built for shooters who demand durability and speed without compromise. This 1x24mm red dot sight pairs a rugged 7075 aluminum housing with a fully sealed, argon-purged optical system—drawing inspiration from Sig's proven MIL-SPEC Romeo-M17 platform. Whether you're running a pistol, shotgun, or rifle, the Romeo-X delivers the rock-solid performance you'd expect from a Sig optic, with a 3 MOA red dot reticle that cuts through clutter and puts you on target fast.
Build quality here is genuine. The housing is machined from aircraft-grade aluminum and sealed tight against the elements; the aspherical lens is distortion-free, and the patent-pending beryllium copper flexure arm keeps everything solid under recoil. The side-load battery system (CR-1632) gives you 20,000 hours of runtime at medium brightness—roughly two years of continuous use—so you're not swapping cells every range trip. Fifteen illumination settings, including three dedicated to night vision, let you dial in the perfect brightness whether you're hunting in daylight or working low-light scenarios. The low sight-line height allows standard iron sight co-witnessing, and the fully enclosed design means your red dot stays protected from impact, dust, and water down to IPX-7 submersion depth.
Adjustments are tactile and precise: 1 MOA per click, with 70 MOA windage and 65 MOA elevation range, and T6 Torx screws ensure you can fine-tune zero without fumbling. Motion-Activated Illumination (MOTAC) keeps the battery alive when it counts and dark when it doesn't. At just 1.1 to 1.2 ounces depending on the model variant, the Romeo-X is light enough for any carry, and it's assembled in the USA. This is a sight built by shooters, for shooters.
| Housing Material | 7075 Aluminum |

| Elevation Adjustment Range | 65 MOA |
| Adjustment Resolution | 1.0 MOA per click |
| Water Resistance | IPX-7 |
| Overall Length | 1.62–1.83 inches |

| Weight (with Battery) | 1.1–1.2 ounces |
The Romeo-X delivers 20,000 hours of runtime at medium brightness setting when using a CR-1632 battery. That's roughly two years of continuous operation, making battery changes infrequent. The side-load battery cap design also makes swaps fast and field-friendly when you do need one.
Yes. The Romeo-X features a low sight-line height that allows co-witnessing with standard-height iron sights, giving you the option to run both simultaneously or fall back to irons if needed.
The sight is rated IPX-7 for water resistance, meaning it can handle submersion in water up to 1 meter for 30 minutes. Combined with its fully sealed and argon-purged optics, the Romeo-X is built to perform in wet and harsh conditions without fogging or internal corrosion.
This particular model uses the DeltaPoint Pro mounting footprint, which is standard on many modern pistols, particularly higher-end duty and performance handguns. Check your firearm's manual or contact us if you're unsure whether your platform is compatible.
