The ROMEO-RS features a convenient side-mounted illumination adjustment button embedded into the polymer housing to prevent accidental interference, and the side-load battery tray makes battery replacements easy to do while maintaining zero. SIG SAUER’s updated footprint design maintains true compatibility with industry-standard optics cuts while allowing for the additional lock-up strength provided by steel recoil pins to eliminate the potential for any lateral shift.
Built in Tualatin, Oregon, the ROMEO-RS was engineered to deliver premium red dot functionality at a cost that’s within reach of any shooter.
