SIG ROMEO-MSR Red Dot Sights

The SIG ROMEO-MSR Gen II is SIG’s compact 1×20 mm enclosed rifle red dot for MSR, carbine, and shotgun rails. A 2 MOA aiming point in red or green. One CR2032 SIG rates at 35,000 hours. Twelve brightness settings, including two night-vision steps. A see-through 1.41 in. absolute co-witness riser. IPX-7. Rotary illumination on the right side.

These three sights are the standalone Gen II dots. ROMEO-MSR Gen II plus JULIET3-Micro or JULIET5-Micro kits live on the ROMEO and JULIET combos page. This is not a ROMEO5 and not a pistol-slide footprint. Confirm the reticle. See also SIG ROMEO5, JULIET magnifiers, and SIG ROMEO red dots.

How to choose

Want black 2 MOA red? That is the standard ROMEO-MSR Gen II. Want the same sight in Flat Dark Earth? Take the FDE 2 MOA red. Want a green aiming point? That is the black 2 MOA green. Magnifier packages are sold as combos, not as these three sights.
