The SIG Sauer JULIET4 is a 4x flip-to-side magnifier that extends the effective range of a red dot sight, then swings aside in an instant for a clean 1x view. Its PowerCam quick-release mount makes attaching, removing and flipping fast and repeatable.
The adjustable diopter dials the view sharp for your eye, and the aluminium housing is built for hard use. It sits at a co-witness-compatible height for AR-pattern rifles.
Finish: Black — also available in Flat Dark Earth.
