The SIG Sauer ROMEO5 Gen II Green Dot Sight is a 1x (non-magnified) micro dot sight with a 20 mm objective and a 2 MOA green dot, weighing 5.1 oz (145 g) and supplied with both a low Picatinny mount and a riser.
Green is the reason to choose this over the red ROMEO5 Gen II. The human eye is more sensitive to green light, so many shooters find the dot appears crisper against dark backgrounds and foliage at the same brightness setting — useful in British woodland where a red dot can wash out.
How it compares
Prefer a red dot? The ROMEO5 Gen II red is the same sight in red. Want a circle-dot reticle? The ROMEO5XDR Gen II adds a 65 MOA circle. Add reach with a JULIET3 Micro 3x magnifier. Browse the SIG ROMEO range, our green dot sights and rimfire and .22 LR optics, or read green vs red dot sights compared.
Ideal for
- Civilian Service Rifle and practical rifle shooting
- Shooters who see a green dot more sharply than red
- Straight-pull AR-15 and lever-release rifles
- Rimfire and .22 LR rifles
