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.
