RHF4 comes in two lengths, 11.5″ and 9.5″, it is a quad rail handguard based on the successful Centurion Arms C4 rail system. It is a lightweight, rugged, 2-piece free float rail that provides a continuous 12 o’clock rail when installed on the upper receiver. Like the C4 system, RHF4 is a rigid rail that clamps to a standard barrel nut on all AR15, 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.
