The Sig Sauer Romeo5 Gen II Elite 1x20mm Compact Red Dot Sight is a ruggedized, highly advanced 1x aiming solution designed for precision on modern sporting rifles and carbines. This specific model comes equipped with a 1.93-inch M1913 I-Beam riser mount, specifically engineered to promote a taller, "heads-up" shooting posture and maximize situational awareness. It features the versatile Quad Ballistic Circle Dot 2.0 reticle, boasting a sharp center dot with distinct ballistic holdover points and a surrounding circle for rapid target acquisition. Optimized for speed and clarity, it utilizes high-performance Mangin lenses and 12 manually adjusted brightness levels (10 daylight and 2 dedicated night vision modes) operated by top-mounted push buttons. To ensure your battery is preserved, Sig's MOTAC™ (Motion Activated Illumination) automatically powers the reticle on when it senses movement and shuts off during periods of rest, providing up to 40,000 hours of runtime on a single CR2032 battery. This black finish unit is rounded out with recessed 0.5 MOA windage and elevation adjustments and an IPX7 waterproof and fog-proof rating.
