Sig Sauer Electro-Optics Romeo5 Gen II 1x 20mm Red Dot Sight - Quad Ballistic Circle Dot 2.0 Reticle - Black

The Sig Sauer Electro-Optics Romeo5 Gen II is a compact, lightweight 1x red dot sight built around a 20mm objective lens and a low-profile Standard I-Beam Mount that clamps directly to a rail. The housing measures just 2.70" long and tips the scales at 5.50 oz, keeping the optic unobtrusive on the host firearm.

This Gen II variant carries the Quad Ballistic Circle Dot 2.0 reticle, giving the shooter a precise central aiming point framed by a circular reference for quick target acquisition. The reticle is illuminated by a common CR2032 coin-cell battery, and Sig Sauer's MOTAC (Motion Activated Illumination) system powers the unit up on sensed motion and shuts it down at rest to extend battery life. The unit offers 12 illumination settings (10 daylight plus 2 night-vision compatible) with a rated 40,000-hour runtime on a single battery.

Adjustment is straightforward with 100 MOA of total windage and elevation travel for dialing in a precise zero. The Romeo5 Gen II carries an IPX-7 waterproof rating for dependable performance in wet conditions and is finished in a durable matte black anodize. The lens system uses Sig Sauer's Spectracoat, Lensarmor, and Lenshield coatings to boost light transmission, increase scratch resistance, and shield the optics from the elements.
