Ultradyne C4 AR-15 Rear Sight is a flip-up backup iron sight (BUIS) for AR-15 platforms. It utilizes Ultradyne's dynalign sight picture technology for fast, accurate acquisitions. The rear aperture is designed to pair with the front sight post for intuitive alignment, aiding quick target acquisition when transitioning from optics to iron sights. The sight folds flat when not in use and rises for use.
