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. Several versions are available for multiple applications.
 
The PTS Centurion Arms C4 Rail Series are licensed airsoft replicas, designed for training and simulation use only.
