FORWARD CONTROLS DESIGN
RHF4 FDE Quad Rail AR-15 Handguard
The FDE anodized version of the RHF4, a lightweight two-piece free float quad rail based on the Centurion C4 system. Available in 9.5 and 11.5 inch lengths.
Also available in black anodize.
Why a Quad Rail
Forward Controls has been running 1913 rails in four quadrants since the KAC RAS in the early 2000s, through every trend toward lighter, slimmer, rails-only-where-you-want-them handguards and back again. Quad rails remain the most versatile and rigid way to attach Picatinny accessories.
When installed on the upper receiver, the RHF4 provides a continuous 12 o'clock rail.
Installs on a Standard Barrel Nut
Like the C4, the RHF4 clamps to a standard barrel nut on any AR-15, M4, or M16, so it installs on an assembled upper without removing a permanently attached muzzle device.
Before You Order
The RHF4 is not compatible with an A2 front sight post without modification.
The RHF4 is not compatible with BCM MK2 uppers.
2021 production RHF4 rails do not have the 1913 rail numbers, the T marks.
What FCD Changed
The built-in QD swivel attachment points are gone. Front and rear QD sockets are common, but FCD's position is that where you put a front sling attachment should be your call, not theirs. For a sling point, the FCD RSF-H Picatinny sling mount attaches anywhere on the rail.
KAC rail panel clip cutouts are present front and back.
Covering the Rails
Bare Picatinny is not comfortable to hold for long. The FCD RCP rail covers carry the AA dimpled texture and come in four lengths.
