The SIG Sauer ROMEO-X Enclosed Compact is a low-profile pistol reflex sight designed for concealed-carrier and duty-style applications where a compact, durable optic is required. It uses a point-source emitter and an aspherical lens system housed in CNC 7075 aluminum to deliver a distortion-free aiming image. The enclosure and IPX-7 waterproof rating protect the optical system while a side-load battery compartment and a beryllium-copper flexure mount keep the deck height low for standard-height iron co-witness. Available in a Flat Dark Earth finish, the ROMEO-X is built for reliability and everyday carry compatibility.

Built around SIG Sauer’s enclosed-emitter design and a low deck height, the ROMEO-X Enclosed Compact blends robust construction and everyday practicality.

The compact footprint and long battery life deliver convenient, long-term service without sacrificing performance.
