SIG Sauer ROMEO5 Gen II 1x20mm 2 MOA Red Dot Sight, Flat Dark Earth

The SIG ROMEO5 Gen II is SIG’s enclosed rifle red dot. The ROMEO5 is a 1×20 mm sight for a Picatinny rail, built to ride a carbine, PCC, or shotgun without turning into a pistol micro dot.

Confirm the reticle, housing, and mount on the sight you receive. This is not a ROMEOZero pistol sight. Mounting hardware in the box is for a MIL-STD 1913 rail unless the product page says otherwise.

This configuration

As a GEN II sight, it uses top-mounted ambidextrous illumination controls, 12 settings (10 daylight and 2 night-vision-compatible), MOTAC motion-activated illumination, and a side-loading CR2032 battery rated for 40,000 hours under standard use. The I-BEAM is specified at 1.41 in. absolute co-witness height on a Picatinny rail. FDE is the finish distinction from black SOR5101. The reticle remains a red 2 MOA dot, not the Elite Quad Ballistic Circle Dot 2.0 and not a green LED. This is still a 1× enclosed tube sight for carbines and PCCs, not a ROMEO-X pistol optic. Adjustments are 0.5 MOA per click with 100 MOA of travel. Housing, IPX-7 sealing, and the 2.7 × 1.6 in. outline follow the black GEN II sight.

What ships

A factory optic is installed only when this page says so. Confirm the reticle on the sight you receive. See the SIG ROMEO5 collection.
