The SIG Sauer ROMEO5 Gen II Green (SOR5102) is a 1x micro red dot sight with a 20 mm objective and a 1 MOA green dot.
Green is the whole reason for this variant. The eye is more sensitive to green than to red, so at the same brightness setting the dot reads as crisper against woodland, hedgerows and dark backstops.
It weighs 5.5 oz and comes on SIG's 1.41 in M1913 I-BEAM mount, which is interchangeable if you want the sight at a different height. Adjustment is 0.5 MOA per click with 100 MOA of travel, power is a CR2032 rated at 40,000 hours with MOTAC waking the dot on movement and sleeping it when the rifle is put down, and the housing is rated IPX-7.
It is a rifle sight for service rifle and practical work, straight-pull carbines and rimfires — anywhere a small, always-ready dot beats magnification. One thing to be clear on: the green Gen II uses a 1 MOA dot, which is finer than the 2 MOA red version and better for precision, but a very fine dot can be harder to pick up at speed than a bolder one.
