SIG SAUER ROMEO-X Enclosed Pro — Rugged, Low-Profile Pistol Red Dot (3 MOA)
Rugged dependability meets precision optics in the SIG SAUER ROMEO-X Enclosed Pro (SORX1380). Built around a sealed emitter and a rock-solid CNC-machined 7075 aluminum housing, this pistol red dot delivers a distortion-free sight picture, long battery life, and practical features tailored for carry, duty, and high-round-count use. If you want a low-profile sight that won’t quit when things get real, ROMEO-X Enclosed belongs at the top of your list.
Why the ROMEO-X Enclosed Stands Out
Built like a tank (that shoots straight). The fully enclosed optical system keeps dust, moisture and impact out of the emitter area for reliable, repeatable performance. The 7075 aluminum chassis gives strength without excessive weight, and the patent-pending beryllium-copper flexure arm provides robust internal support and shock resistance.
Cleaner, truer sight picture. An aspherical glass lens combined with a high-efficiency point-source emitter delivers a crisp, distortion-free reticle that’s easy to pick up in dynamic situations.
Designed for real carry. Low deck height allows standard-height iron-sight co-witnessing, while MOTAC (Motion Activated Illumination) and long battery life mean the dot is ready when you are—without constant battery babysitting.
