Description
The SIG Sauer JULIET3 Magnifier is a full-size 3x flip-to-side magnifier that extends the effective range of any red dot sight, then swings aside in an instant for a clean 1x view. It's a proven, no-fuss upgrade for an existing red dot setup.
The push-button quick-detach mount makes transitions fast and one-handed, and an adjustable diopter dials the view sharp. The aluminium housing is IPX7-rated, fogproof and shockproof, and it ships with a spacer for absolute or lower-1/3 co-witness height.
How It Compares

Frequently Asked Questions
What does it pair with?
Any red dot sight at a compatible mounting height — it sits behind the dot to add 3x magnification.
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, or detach it entirely.
