Sig Sauer Electro-Optics Romeo-X Enclosed Pro 1x24mm 6 MOA Green Dot Red Dot Sight - Black

The Sig Sauer Romeo-X Enclosed Pro is a rugged enclosed-emitter pistol red dot built for duty, defensive, and competition use. Inspired by the MIL-SPEC ROMEO-M17, the optic uses a fully enclosed, sealed, and argon-purged optical system housed in 7075 aluminum to protect the emitter from the elements, debris, and the rough handling that comes with slide-mounted carry.

The aspherical glass lens delivers a crisp 1x sight picture through a 24mm objective window and is paired with a 6 MOA green dot reticle for fast, intuitive target acquisition that remains precise enough for defensive work. The side-loading CR2032 battery is rated for up to 20,000 hours of runtime, with MOTAC motion activation that wakes the optic on draw and conserves power at rest so the dot is always there when you need it.

Built on the popular RX footprint, the Romeo-X Enclosed Pro drops onto a wide range of modern pistol slides cut for that pattern. The housing measures just 1.83" long with 65 MOA of windage adjustment, keeping a compact, low-profile co-witness on duty pistols and carry guns. Finished in matte Black anodize and ready for slide mounting right out of the box.
