The ROMEO-RS is a pistol-mounted red dot built around a reinforced steel chassis molded into a high-strength polymer housing. An aspherical glass lens and point source LED emitter deliver a clear sight picture with 8 brightness settings, controlled by a side-mounted button. A side-load CR1632 battery tray allows battery changes without removing the optic, helping maintain zero, and includes a security screw. Metal inserts support mounting torque and provide durable windage and elevation adjustments, with an updated footprint compatible with industry-standard optics cuts.
