The Sig Sauer Romeo Zero RMR Reflex Reis the ultimate micro red dot reflex sight engineered specifically for slim-profile pistols. Compact, lightweight, and rugged, it’s built to deliver rapid target acquisition and precision in a minimalist footprint.
Crafted from weapons-grade ultralight polymer, the Romeo Zero offers exceptional durability without adding unnecessary bulk. A hardened steel shroud enhances protection against impact, ensuring reliable performance under stress.
With 8 user-selectable brightness levels, the 3 MOA red dot adapts to any lighting condition, while its efficient power management system delivers up to 20,000 hours of runtime on a single CR1632 battery.
