Centurion Arms C4 Quad Rail Handguard – Carbine Cutout
The Centurion patent-pending C4 rail system is a lightweight, rugged, 2-piece free-float rail that, when installed, gives the upper a continuous 12 o’clock rail. The C4 system is the lightest and most rigid rail that clamps to a standard barrel nut on all AR-15, M4, and M16-type weapon systems. This design allows the installation of the rail on an upper assembly without removing the front sight post or permanently attached muzzle devices.
