The Sig Sauer Romeo-RS Pro delivers professional-grade optical performance in a compact 1x31mm package designed for rapid target acquisition across multiple shooting disciplines. This red dot sight combines Sig's proven electro-optics technology with enhanced durability features that maintain zero under heavy recoil and environmental stress.
What Makes This Different
The Romeo-RS Pro stands apart from standard red dot sights through its 31mm objective lens diameter, providing a wider field of view than typical 20mm optics while maintaining the same mounting footprint. The 6 MOA dot size offers faster target acquisition at close to medium ranges compared to smaller 2-4 MOA dots, making it particularly effective for defensive applications and dynamic shooting scenarios. Sig's SpectraCoat lens coatings deliver 98% light transmission with reduced glare and distortion.Key Features
