Inspired by the MIL-SPEC ROMEO-M17, the ROMEO-X is a micro reflex sight that’s ready to be mounted on the vast majority of optics ready pistols. This compact, high-performance optic offers excellent durability thanks to a forged 7075 aluminum housing – this allows the ROMEO-X to easily withstand minor impacts, as well as the recoil of the potent 10mm cartridge. One of the ROMEO-X’s more intuitive features is the MOTAC Motion Activated Illumination which activates the reticle when motion is detected, so the optic is always at the ready when you need it. The reticle is projected by an open emitter onto a distortion-free aspherical glass lens, giving the user a clear sight picture for faster target acquisition and engagement. Other features of the ROMEO-X include a low deck height, as well as a back-up rear sight which can be used to co-witness with standard height iron sights. In addition, the ROMEO-X features a convenient side-mounted battery compartment for replacing the battery without removing the optic from the host weapon, as well as tactile buttons for easy adjustments.
