Sig Sauer ROMEO4A 2 MOA 1x20mm Compact Red Dot Sight


In stock


The ROMEO4A 2 MOA Red Dot Sight features unlimited eye-relief allows you to acquire the aiming point and the target regardless of the position of your eye behind the sight. An ultra-efficient red LED illumination system with user selectable brightness settings provides visibility with extended runtime in all lighting conditions. MOTAC (Motion Activated Illumination System) powers up ROMEO4A when it senses motion and powers down when it does not, providing optimum operational safety and enhanced battery life ( 50,000 hours). The readily available CR2032 battery is side loading, allowing for quick battery replacement without removing the sight.

The extremely robust design and construction of the ROMEO4A, combined with waterproof (IPX-7) and fog-proof performance, ensures a lifetime of reliable service in a wide range of environmental conditions. The ROMEO4A includes both a low profile mount (ideal for hunting rifles and shotguns) and a high mount (1.41″ above rail) for AR-style iron sight co-witness.
