The SIG Sauer JULIET3 Micro is a compact 3x flip-to-side magnifier that extends the reach of a red dot sight while keeping system weight and size to a minimum — its micro body is noticeably more streamlined than a full-size magnifier. Flip it in for magnified target ID, then swing it aside for 1x speed.
The push-button quick-detach mount makes transitions fast and one-handed, and an adjustable diopter dials the view sharp. IPX7-rated, fogproof and shockproof, with a spacer for absolute or lower-1/3 co-witness.

Frequently Asked Questions
Micro or full-size JULIET3?
The Micro is smaller and lighter for streamlined builds; the full-size JULIET3 has the same 3x optics in a larger body.
Does a magnifier have its own reticle?
No — it magnifies the reticle of the host red dot.
Can I flip it aside?
Yes — the flip-to-side mount swings it out of the way for 1x.
