Description
SIG Sauer ROMEO5 Gen II Elite Red Dot Sight is the Gen II with two upgrades that matter: the Quad Ballistic Circle Dot 2.0 reticle, giving four selectable aiming options instead of one dot, and a 1.41 in mount in the box that puts the optic at absolute co-witness height with standard AR iron sights straight away.

Help & guidance
Product FAQs
What does the Quad reticle on the ROMEO5 Gen II Elite give me?
The Quad Ballistic Circle Dot 2.0 gives four selectable aiming options in one optic, including a dot, a circle-dot and ballistic holds. You change the reticle rather than the sight.
What is the 1.41 in mount on the ROMEO5 Gen II Elite for?
It sets the optic at absolute co-witness height with standard AR iron sights, so the irons and the dot line up through the same window. The mount is included with the SOR5105.
Should I buy the ROMEO5 Gen II Elite or the standard Gen II?
The Elite adds the four-option reticle and the 1.41 in absolute co-witness mount, while the standard Gen II is a single 2 MOA dot with a low mount and riser. Pick the Elite if you want reticle choice and co-witness height out of the box.
What battery does the SIG Sauer ROMEO5 Gen II Elite take?
It takes one CR2032, loaded from the side, good for around 40,000 hours with MOTAC. Side-loading means no re-zero when you change it.
How many brightness settings does the ROMEO5 Gen II Elite have?
The SOR5105 has 10 daylight settings plus 2 night-vision settings. MOTAC motion activation switches the reticle on and off with movement.
