The SIG Sauer ROMEO5 Gen II Elite Red Dot Sight is a 1x (non-magnified) micro red dot sight with a 20 mm aperture and the Quad Ballistic Circle Dot 2.0 reticle in red, supplied on a 1.41 in absolute co-witness I-BEAM mount. It weighs 5.5 oz (156 g) without the battery.
Two things separate the Elite from the standard ROMEO5 Gen II: the four-mode Quad Ballistic Circle Dot 2.0 reticle, which lets you choose between a plain dot and circle-dot configurations, and the I-BEAM mount supplied at a fixed 1.41 in absolute co-witness height.
How It Compares
Want a plain 2 MOA dot and both mount heights in the box? The ROMEO5 Gen II is the standard model. Prefer a circle-dot on an AAA cell? See the ROMEO5XDR Gen II. Pair it with a JULIET3 Micro 3x magnifier. Browse the SIG ROMEO range, all rifle red dot sights and optics for straight-pull rifles.
