Sig Sauer Electro-Optics Romeo-X Sig-Loc Pro 1x 3 MOA Red Dot Sight - Black Cerakote

The Sig Sauer Electro-Optics Romeo-X Sig-Loc Pro is a sealed, enclosed 1x reflex red dot built for slide-mounted pistol use on SIG's proprietary Sig-Loc footprint. Designed as a duty-grade optic, the housing is fully enclosed and purged to lock out moisture, dust, and debris for rock-solid reliability in adverse conditions.

A distortion-free aspherical glass lens paired with SIG's LensArmor and SpectraCoat anti-reflection coatings delivers a crisp sight picture, while a precise 3 MOA red dot reticle gives a clean aiming point for fast, accurate shooting. The optic is built around a rugged 7075 aluminum housing and finished in a low-glare, corrosion-resistant Black Cerakote.

At just 1.90 in long and 1.46 oz, the Romeo-X Sig-Loc Pro adds minimal bulk to a pistol slide. Illumination runs through 15 brightness settings, including 3 night vision compatible levels, and is managed by MOTAC motion-activated technology that powers the unit up when drawn and down when at rest to conserve battery life. A side-loading CR2032 battery is rated for up to 20,000 hours of runtime and can be swapped without removing the optic or losing zero.

Windage and elevation adjustments click at 1.50 MOA per increment for fast, tactile zeroing. The Romeo-X Sig-Loc Pro is purpose-built for shooters who want a sealed, low-profile enclosed reflex with the refined 3 MOA dot that has become the standard for modern defensive and duty pistols.
