The Sig Sauer Romeo-X Enclosed Compact is a rugged pistol red dot built for serious shooters who demand reliability without compromise. This enclosed optic combines CNC-machined 7075 aluminum construction with a fully sealed optical system designed to handle concealed carry, duty, and hard use in the field. Its low profile and compact footprint make it ideal for co-witnessing with standard-height iron sights—a critical feature for shooters who want backup aiming and fast target acquisition.
What sets the Romeo-X Enclosed apart is its engineering heritage: Sig drew on decades of military red-dot development to create an optic that prioritizes durability and optical clarity. The aspherical glass lens delivers distortion-free sight picture, while the high-efficiency point source emitter produces a sharp, clean 6 MOA green dot across 15 illumination settings (12 daytime and 3 night vision compatible). Battery life is exceptional at 20,000 hours; the side-load CR1632 placement keeps the optic slim and accessible without breaking your shooting grip.
The patent-pending beryllium copper flexure system absorbs recoil and vibration, maintaining zero through thousands of rounds. Motion Activated Illumination (MOTAC) preserves battery life by powering down the dot when the gun sits still. With IPX-7 waterproofing, 65 MOA elevation and 70 MOA windage travel, and RX-footprint (Shield RMS-c) mounting compatibility, this is a compact red dot engineered for pistols that demand reliability. Assembled in the USA.
| Reticle Type | 6 MOA Green Dot |
| Objective Lens Diameter | 24 mm |
| Height | 0.94" (23.88 mm) |
| Length | 1.62" (41.15 mm) |
| Width | 1.23" (31.24 mm) |
| Illumination Settings | 15 (12 daytime, 3 night vision) |
| Elevation Travel | 65 MOA |
| Windage Travel | 70 MOA |
| Battery Type | CR1632 |
| Battery Life | 20,000 hours |
| Waterproofing Rating | IPX-7 |
| Mounting Footprint | RX (Shield RMS-c) |
| Housing Material | CNC 7075 Aluminum |
| Optic System | Fully enclosed, aspherical glass lens |
The Romeo-X Enclosed Compact uses the RX footprint, which is compatible with Shield RMS-c mounting systems. Check your pistol's compatible optic footprints to confirm fit, or contact us for specific platform compatibility.
Yes. The Romeo-X Enclosed Compact has a low deck height of 0.94 inches, allowing for natural co-witness with standard-height iron sights. This means you can use your irons for aiming and the red dot as a secondary or backup aiming solution.
The Romeo-X Enclosed Compact features 3 night vision illumination settings out of 15 total brightness levels, allowing the green dot to be used with night vision devices. The remaining 12 settings are optimized for daytime shooting.
The Romeo-X Enclosed Compact delivers 20,000 hours of runtime on a single CR1632 battery, which translates to roughly 2+ years of continuous operation. The side-load battery compartment makes swaps quick and convenient without removing the optic from your pistol.
Yes, the optic has an IPX-7 waterproofing rating, meaning it can handle submersion in up to 1 meter of water for up to 30 minutes. The fully enclosed, sealed optical system protects internal components from moisture and dust in wet or challenging environments.
