More durable. More versatile. More features than ever before. The new SIG SAUER Romeo2 is one of the most robust and full-featured Reflex Sights we've seen in some time, combining an interchangeable shroud design with enhanced toughness. Responding to military and law enforcement personnel, SIG increased material thickness in every area, making the Romeo2 significantly more durable than the original models-so it's capable of operating in some of the worst conditions imaginable. It also features a totally unique interchangeable shroud design. The half shroud gives the Romeo2 the look and feel of a standard reflex sight, and shaves a few grams off the overall weight. The full shroud turns the Romeo2 into a fully sealed, enclosed, and water-resistant Sight that functions in rain and snow. Swapping between the shrouds is simple-just use the included multi-tool to remove 2 screws. The Romeo2 features an outstanding 25,000 hours of battery life, and features a spring-loaded battery tray for easy battery swaps. To enhance run time even more, the Romeo2 features MOTAC motion-activated illumination that powers the unit up when it senses movement and shutting the unit down after 2 minutes idle. And with smart features like MAGNETAC magnetic activation with compatible holsters (holster not included), the Romeo2 is one of the most capable Reflex Sights we offer. 3 MOA red dot 15 brightness settings Molded aspheric glass lens with high-performance coatings MOTAC (Motion Activated Illumination) Includes 2 shrouds (half shroud and full shroud) MAGNETAC magnetic activation automatically turns the optic on when drawn from a compatible holster, and turns the unit off when re-holstered (compatible holster not included) Same footprint as Romeo1, and can be directly mounted to any SIG pistol with a pro slide cut 25,000 hours run time on (1) CR2032 battery Spring-loaded battery tray for simple, tool-free battery swaps D.A.R.C.
