The Centurion C4 drop in, free float 2 piece rail system features a patent pending design which is not only lightweight but is extremely rugged. When installing on a flat top AR-15, this 2 piece free float system will provide you with a continuous 12 O'Clock rail. This 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 system on any carbine length upper assembly without going through the hassle of removing the front sight post, or trying to remove muzzle device especially if it is permanently attached.
