Sig Sauer ROMEO-MSR GEN II 1x20MM Red Dot Sight Red

Built for modern sporting rifles, the SIG SAUER ROMEO-MSR GEN II 1x20mm red dot sight delivers fast target acquisition with a clean 2 MOA dot and true 1x performance—so you stay both-eyes-open and on target in close to mid-range engagements.

A 20 mm clear aperture and parallax-free optical design give you a forgiving sight picture for rapid transitions, while the analog rotary illumination dial provides 12 brightness settings (10 daylight + 2 night vision) to match changing light without menu diving. With up to 35,000 hours of runtime on a single CR2032 battery, it’s engineered for long duty cycles and reduced maintenance. The redesigned see-through riser mount supports convenient co-witnessing on MSR platforms, and 100 MOA adjustment range helps you zero confidently and keep your optic dialed in.

Choose the ROMEO-MSR GEN II for patrol carbines, training rifles, range work, and practical shooting where speed, clarity, and repeatability matter. IPX7 waterproof and fog-proof construction keeps the optic running in rain, mud, and temperature swings.

Backed by SIG SAUER’s reputation in electro-optics and the fully transferable Infinite Guarantee, this compact red dot is positioned for serious users who demand dependable performance.
