Ultradyne C4 Offset Folding Front & Rear Iron Sights – 5.56/.308

The Ultradyne C4 Offset Folding Sight Combo gives AR-15 and AR-10 shooters a serious backup sighting option that stays out of the way until you need it. Mounted at a 45-degree offset, this front and rear sight pair folds flat to clear your top rail for a red dot or LPVO, then flips into action in an instant if your primary optic ever fails or you need a fast close-range transition.

Both sights fold via a positive detent for reliable one-handed deployment and stowage, rather than a spring-loaded mechanism. The front sight uses a dual-aperture, Dynalign concentric-circle design with windage adjustment and tool-less elevation across nine settings, while the rear sight adds rapid windage and elevation adjustment of its own. The set is fully machined from 416 stainless steel and 6061-T6 aluminum and mounts directly to a Picatinny rail.
