SIG SAUER – ROMEO-RS Compact Open Emitter Red Dot

The SIG SAUER ROMEO-RS Compact is a pistol-mounted red dot engineered to deliver premium performance, durability, and ease of use at a price point competitive with high-end iron sights. Built around a reinforced steel chassis molded into a high-strength polymer housing, the ROMEO-RS balances strength, weight, and long-term reliability.

Inspired by modern striker-fired pistol design, the optic’s hybrid construction protects a premium molded glass aspherical lens, providing a distortion-free sight picture and consistent point-of-aim. Threaded metal inserts ensure proper torque retention when mounting to a slide and when securing the side-load battery tray.

• Hybrid design with skeletonized steel chassis molded into high-strength polymer housing
• Molded glass aspherical lens for a clear, distortion-free sight picture
• High-efficiency point source LED emitter with 8 brightness settings
• Large side control button for quick, intuitive reticle adjustment
• Side-mounted CR1632 battery tray with security screw for battery changes without removing the optic
• Minimum 20,000-hour runtime at medium brightness (dot only)
• MOTAC™ motion-activated illumination powers on with movement and powers down when idle
• Raised steel housing protects controls from accidental activation
• Open emitter design with Red Circle Dot reticle

The ROMEO-RS features SIG SAUER’s updated optic footprint, maintaining compatibility with industry-standard compact optics cuts while adding the locking strength of SIG-LOC™ recoil pins to prevent lateral shift under recoil. Windage and elevation mechanisms are reinforced with metal inserts for precise, repeatable adjustments.

Designed, developed, tested, and assembled in the USA and fully backed by SIG SAUER’s Infinite Guarantee™, the ROMEO-RS Compact is built for everyday carry, duty use, and range performance without compromise.
