Sig Sauer Romeo5 2 MOA Red Dot

The Sig Sauer Romeo5 is the compact 1x20mm red dot that put Sig optics on a lot of AR carbines. It runs a 2 MOA red dot with 10 brightness settings, 8 for daylight and 2 for night vision, and MOTAC motion activation that powers the dot up when the rifle moves and shuts it down when it sits.

The CR2032 battery loads from the side, so you can swap it without pulling the sight off the gun. An integrated M1913 Picatinny interface handles mounting, and the box includes a low mount riser plus a 1.41 inch co-witness riser for use with AR height iron sights. The housing is aluminum, the sight weighs 5.1 oz, and it is rated IPX-7 waterproof and fog proof. Unlimited eye relief and a low parallax design keep the dot on target even when your head position is not perfect.
