The SIG Sauer ROMEO5 Gen II + JULIET3-Micro combo bundles SIG's proven entry red dot with a compact 3× magnifier — a budget-friendly way to add reach to a carbine without buying the two pieces separately. The ROMEO5 Gen II offers a crisp 2 MOA red dot with MOTAC motion activation; the JULIET3-Micro flips into place for 3× magnified target ID, then swings aside for 1× speed.
It is the lighter, more affordable sibling to the ROMEO5XDR + JULIET5 5× combo — ideal if you want some magnification without the size, weight or cost of a higher-power setup. MOTAC stretches battery life to 40,000 hours on a CR2032, and both optics mount to standard Picatinny rails. In stock for fast UK dispatch.
