New Item Unboxing

Launching June 13th, 2025
The Centurion patented C4 rail system is a lightweight, rugged, 2-piece free-float rail that, when installed, gives the uppers 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 weapons systems. This design allows the installation of the rail on an upper assembly without removing the front sight post or permanently attached muzzle devices.
