The SIG Sauer ROMEO1PRO Red Dot Sight in this listing is the 6 MOA version — a 1x (non-magnified) open reflex pistol red dot sight with a 30 mm objective lens, 12 brightness settings and a CR1632 cell rated to 20,000 hours.
A 6 MOA dot inside a 30 mm window is about as fast as a pistol optic gets: the large lens makes the dot easy to find on presentation, and the bigger dot draws the eye quickly in poor light, at the cost of covering more of a distant target than the 3 MOA version.
Finish: Black — also sold as the ROMEO1PRO 6 MOA red dot sight in FDE.
