Ultradyne C4 Flip-Up Front and Rear Combo Sight

The Ultradyne C4 Front/Rear Sight Combo is a dual aperture sighting system that redefines iron sight performance. The C4 Rear Sight delivers reliable function in a compact package, featuring ballistic calibration with elevation adjustment in 50-yard increments spanning 200 to 600 yards. The C4 Front Sight incorporates precision front aperture technology for backup iron sight use, with the ability to adjust both windage and elevation. Paired together, these sights produce a perfectly concentric sight picture that keeps the target in view, accelerates sight acquisition, and supports consistent accuracy out to 600 yards and beyond. All of this capability comes in compact, foldable iron sights.
