The S4 4-16x44 is a first focal plane riflescope designed for air rifles and .22 LR rifles. The VIS-FMIL reticle is etched on glass and scales with magnification, so the markings remain accurate at every zoom level.
Parallax focus is side-mounted and starts from 15 yards, a useful distance for airgun shooting. The turrets feature a push-to-lock system: pull to adjust and push down to lock. The 30mm tube is made of 6061-T6 aluminum alloy with a matte black finish, nitrogen-filled, and splash-proof according to IPX4.
