Sig Sauer Electro-Optics Sor21601 Romeo2 Black Anodized 1X30Mm 6 Moa Red Dot Reticle, Fits Pistols (Pro Rx Footprint) Features Large Shroud

The Sig Sauer Romeo2 with large shroud is a 1x30mm red dot sight built for shooters who demand rugged performance in tough conditions. Designed for direct mounting on Sig Sauer pistols with the PRO RX footprint, this closed-lens optic delivers the same battle-tested reliability Sig is known for, but with full steel shroud protection to keep dust, debris, and moisture off your glass and emitter. If you run a modern Sig handgun and want a no-compromise red dot for carry or competition, the Romeo2 large shroud is built to handle it.

The sight pairs a high-efficiency LED emitter with molded aspheric glass and precision coatings for clean, bright target images without distortion. You get 12 daylight brightness settings plus 3 more tuned for night vision compatibility via Sig's D.A.R.C. technology—plenty of adjustment to dial in the reticle in any light. The 6 MOA red dot option here is a proven size for fast target acquisition on handgun distances, and your elevation and windage adjustments max out at 100 MOA total travel in either direction. The real-world convenience: spring-loaded side battery access means you can swap your CR2032 without breaking down the optic, and Sig's MOTAC motion-sensing system will power the sight on when drawn and back down when it sleeps to stretch that 25,000-hour runtime even further.

Built from 7075 aluminum with a full-length steel shroud, the Romeo2 shrugs off the abuse pistol optics take. The housing is U.S.-designed, developed, tested, and assembled, and it includes a rubber sight cover, lens pen, and multi-tool in the box—practical stuff that gets used. For Sig Pro-cut slide owners after a closed-lens, shrouded red dot that runs reliably from the range to the holster, this is the real deal.

Specifications

Frequently Asked Questions

Will the Romeo2 large shroud fit my Sig pistol?

This sight is designed for direct mounting on any Sig Sauer pistol with the PRO RX footprint (the newer PRO-cut slide). It will not fit DeltaPoint PRO footprints on other brands due to recoil boss dimension differences, and compatibility with older Sig models depends on whether they have the PRO RX cut. If you're unsure about your slide, double-check your pistol's specs before ordering.

Can I change the battery without removing the sight?

Yes. The Romeo2 features a spring-loaded side battery tray that opens with a push button. You can swap out the CR2032 battery without taking the optic off your pistol.

Does this sight work with night vision?

Yes. The sight includes 3 brightness settings tuned specifically for use with night vision devices via Sig's D.A.R.C. (Dark Adaptive Reticles & Coatings) technology, which optimizes reticle brightness and target clarity when paired with Gen3+ night vision.

What's included in the box?

The Romeo2 comes with a magnetac rubber sight cover, a lens pen for cleaning, and a fix-it-sticks multi-tool. You'll also receive a half shroud as an accessory.
