The Sig Sauer Romeo-RS Compact Footprint Red Dot (Sig Sauer part no. SOR02100) in black is built around a skeletonized steel chassis molded into a high-strength polymer housing, giving it genuine steel-reinforced durability at a price that competes with high-end iron sights. It uses SIG’s RMS/c industry-standard footprint along with steel recoil pins to eliminate lateral shift, and a premium molded aspherical glass lens keeps the 1 MOA red circle-dot reticle distortion-free. A side-load CR1632 battery tray with a security screw lets you swap batteries without losing zero, and MOTAC motion-activated illumination powers the optic up automatically and shuts it down when it’s not moving. Designed, developed, tested, and assembled in Tualatin, Oregon, the Romeo-RS is backed by SIG Sauer’s Infinite Guarantee.
