Sig Sauer Romeo-X Reflex Pro Circle Dot Sight - Black$449.99
Availability: In Stock
The Sig Sauer Romeo-X Compact reflex sight delivers military-grade red-dot performance in a slim profile built for modern optics-ready pistols. This open-emitter sight pairs a 2 MOA red dot with a 32 MOA circle reticle, giving you both precision aiming and rapid target acquisition in a single glass plane. Whether you're running a P365, Shield RMSc footprint, or R1P/R2 mount, the Romeo-X Compact installs directly without adapters and sits low enough to co-witness with standard-height iron sights—a real advantage if you want backup aiming capability without losing glass real estate.
Built from CNC-machined 7075 aluminum, the Romeo-X Compact is rugged enough for duty and refined enough for the range. The side-load battery compartment is quick to access, and the MOTAC motion-activated illumination system keeps the dot bright when you need it and preserves battery life when you don't. With 20,000 hours of runtime on a single CR1632 battery and 15 total illumination settings—12 for daylight and 3 tuned for night vision—you're covered from dawn shooting to after-dark training. All adjustments dial in 1.5 MOA increments across an 80 MOA travel window both directions, and IPX-7 waterproofing handles the elements without flinching.
Designed, tested, and assembled in the USA, the Romeo-X Compact distortion-free aspherical lens and patent-pending beryllium copper flexure arm are engineered to survive hard use. At just 1 ounce and 1.62 inches long, it won't shift your carry balance or slow your draw. This is the sight Sig built for shooters who want reliability they can trust without the hype.
