The SIG Sauer ROMEO5 Gen II Elite Red Dot Sight is a compact 1x20 rifle red dot sight that upgrades the hugely popular ROMEO5 with a ballistic reticle and a refined housing. It's built for fast both-eyes-open shooting on AR-pattern rifles and carbines.
This Elite model runs the Quad Ballistic Circle Dot 2.0 reticle (1 MOA centre dot with 0.7 MOA holdover dots) for extended-range references, MOTAC motion activation, 12 brightness settings (10 day / 2 NV) and up to 40,000 hours on a CR2032. It ships with a 1.41in absolute co-witness I-BEAM mount and is IPX7 sealed.
