The SIG Sauer ROMEO5 Gen II Red Dot Sight and JULIET3-Micro Magnifier Combo pairs the 1x ROMEO5 Gen II red dot — a 2 MOA red dot in a 20 mm objective — with the JULIET3-Micro 3× magnifier, both on Picatinny (M1913) mounts. The pair weighs 15.4 oz (437 g).
Buying the two together is the point: the magnifier is height-matched to the sight, so the magnified image sits centred behind the dot with no shimming. The ROMEO5 runs 10 daylight and 2 night-vision brightness settings from a CR2032 with a 40,000-hour rating.
How It Compares
Want the sight on its own? The ROMEO5 Gen II is sold separately, as is the JULIET3 Micro magnifier. Want 5× and a circle-dot reticle? The ROMEO5XDR Gen II with JULIET5-Micro is the bigger combo. Browse all red dot and magnifier combos and read how to choose a magnifier.
