The Sig Sauer Romeo5 red dot sight delivers professional-grade optical performance in a compact, battle-tested package. This 1x20mm optic features a crisp 2 MOA red dot reticle that provides rapid target acquisition for tactical applications, competitive shooting, and hunting scenarios.
What Makes This Different
The Romeo5 incorporates Sig's MOTAC (Motion Activated Illumination) technology, automatically powering on when motion is detected and shutting down when stationary to preserve battery life. The sight runs for up to 40,000 hours on a single CR2032 battery, significantly outperforming standard red dots that typically offer 5,000-10,000 hours of operation. The aircraft-grade aluminum housing withstands repeated recoil from high-powered rifles while maintaining zero retention.
Key Features
- MOTAC motion-activated illumination with 40,000-hour battery life
- 10 daylight and 2 night vision compatible brightness settings
- Waterproof to IPX-7 standard and fog-proof performance
- Low 1/3 co-witness mount and absolute co-witness spacer included

Field testing demonstrates consistent point-of-impact retention through thousands of rounds across multiple rifle platforms. The Romeo5 maintains zero through temperature extremes from -40°F to +160°F, making it suitable for law enforcement patrol rifles, competition carbines, and hunting applications. The 2 MOA dot subtends approximately 2 inches at 100 yards, providing precise aiming points without obscuring targets at extended ranges.
