The SIG Sauer JULIET3 Micro Magnifier 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.

Should I choose the JULIET3 Micro or the 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 the SIG Sauer JULIET3 Micro magnifier have its own reticle?
No — the SIG Sauer JULIET3 Micro has no reticle of its own; it magnifies the reticle of the red dot sight in front of it.
Can the SIG Sauer JULIET3 Micro be flipped aside?
Yes — the SIG Sauer JULIET3 Micro sits in a flip-to-side mount that swings it clear of the optic for 1x shooting.
Is the SIG Sauer JULIET3 Micro waterproof?
Yes — the SIG Sauer JULIET3 Micro is rated IPX7 water-immersion rating.
