## Description

SIG SAUER ROMEO-X ENCLOSED PRO REFLEX SIGHT: Building up SIG SAUER's DNA of trusted military innovation, the ROMEO-X Enclosed Pro delivers streamlined dependability without compromise. TECHNOLOGIES: - ALT - Precision molded aspheric lens technology virtually eliminates aberration, reduces weight, and helps to focus the projected image through the lenses for superior low-distortion optical performance; - SpectraCoat - Highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission; - Motac - Activated through motion sensing technology, MOTAC immediately powers up illumination when it senses motion and powers down when it doesn't in order to extend battery life; - MAGNETAC - Magnetic Activation - A sensor in the optic detects a Neodymium magnet inside a compatible holster, automatically turning the optic off when holstered, conserving battery life. When the weapon is drawn from the holster, the optic instantly turns on to the last setting used; - D.A.R.C. - Dark Adaptive Reticles & Coatings - Specialized lens coatings and reticle brightness settings that are optimized for use with GEN 3+ NV devices; - Infinite Guarantee - SIG SAUER Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very nice
*by Q***Y on November 28, 2025*

Very nice quality, fit perfectly on my P229 Legion. A little hard to get it to zero but very good overall

### ⭐⭐⭐⭐⭐ Pistol optic
*by D***E on January 25, 2026*

It is a very good optic for my pistol.

### ⭐⭐⭐⭐⭐ EXCELLENT OPTIC!
*by C***R on August 5, 2025*

One of the best optics I have ever purchased. Basically, Sig took their Romeo 1 Pro optic that comes with a metal shroud in some formats, and encased the metal (steel) in polymer to created a steel reinforced optic. I use mine on a competition match grade pistol. It produces excellent results. 98% lethal hit ratio! And I'm an.d guy with glasses. I ordered mine with the reticle and dot selectable choice of sight pictures. Great performance for a lower price than other higher priced optics.
