Sig Sauer Electro-Optics Romeo-X Sig-Loc Compact 1x24mm 3 MOA Red Dot Reflex Sight - Cerakote Black

The Sig Sauer Electro-Optics Romeo-X SIG-LOC Compact is a rugged enclosed-emitter red dot reflex sight purpose-built for slide-mounted carry and duty pistol applications. It pairs a 1x viewing window with a crisp 3 MOA red dot reticle, all wrapped in a 7075 aluminum housing finished in Cerakote Black for corrosion resistance and a low-glare signature.

A 24mm objective feeds the aspherical glass lens, treated with Sig Sauer's LensArmor and SpectraCoat coatings to cut glare and boost light transmission. Windage and elevation adjustments click at 1.50 MOA per increment, and the optic is sealed to waterproof standards for confident all-conditions carry.

Power comes from a side-loading CR1632 battery rated for up to 20,000 hours of runtime, so you can swap cells without removing the sight from the slide. The proprietary SIG-LOC mounting interface establishes five points of contact between the optic and the slide for a return-to-zero hold that survives recoil, draw, and rough handling. The whole package measures just 1.67\" long and weighs a featherlight 1.24 oz.
