The Centurion Arms C4 Rail System is a 2 piece free float rail that, when installed, gives AR uppers a continuous 12 o'clock rail. Its features, some of which are patent pending, also include very light weight, integrated QD mount points, the ability to simply install onto a standard barrel nut, and design features that prevent the rail from loosening and rotating under prolonged stress.
