NOTE: RHF-C uses a TDP spec barrel nut (not included), the barrel nut can be purchased on our site. RHF-C isn't compatible with the A2 FSP without modification.
RHF-C is essentially a RHF4, but with MLOK at 3, 6, and 9 o'clock. RHF-C is lighter for not having 1913 rails at these locations, and offers the modularity and flexibility, and weight saving of MLOK.
RHF-C comes in two lengths, 11.5" and 9.5", it is a hand guard based on the successful Centurion Arms C4 MLOK 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 MLOK system, RHF-C 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.
RHF-C incorporates Forward Controls design input: Omission of built-in QD swivel attachment points. Some like the now common front and rear located QD sockets, we prefer the location of the front sling
attachment be left to individual users. The rail numbers are machine engraved, and a subdued Cygnus is engraved on the right side of the RHF4.
