The SIG Sauer ROMEO5XDR Gen II Red Dot Sight is a 1x (non-magnified) red dot sight with a 20 mm objective and a 2 MOA dot inside a 65 MOA circle, running from a single AAA cell for up to 50,000 hours. It weighs 6.4 oz (181 g).
Two things distinguish the XDR from the standard ROMEO5: the circle-dot reticle, which gives a large ring for fast close-range work around a fine dot for precision, and the AAA cell, which is easier to source in a hurry than a coin cell. Its integrated Picatinny mount ships with two heights.
How it compares
Want a plain 2 MOA dot? The ROMEO5 Gen II is lighter at 5.1 oz on a CR2032. Want a magnifier included? The ROMEO5XDR Gen II with JULIET5-Micro magnifier is the combo. Want a larger 38 mm window? See the ROMEO4T. Browse the SIG ROMEO range, all rifle red dot sights and optics for straight-pull rifles.
Ideal for
- Civilian Service Rifle and practical rifle shooting
- Practical shotgun and 3-Gun stages where the circle helps
- Straight-pull AR-15 and lever-release rifles
- Shooters who prefer an AAA cell to a coin cell
