Forward Controls have long been fans of the classic KAC RAS since the early 2000s.  Throughout the years, they've seen trends for lighter, small diameter, and rails-only-where-you-want-them handguards, this was before the advent of Keymod and MLOK.  Then quad rail made a comeback.  They don't follow trends for many reasons, chief among them is practical designs aren't subject to ever change fads that are quite aimless in their opinion, practical and durable designs are always useful, regardless of which way the wind blows.

They've stayed with hand guards with 1913 rails in four quadrant for their versatility, and they weren't concerned with the then popular, now less popular ways of using the support hand to grasping the handguard, which called for their being of smaller diameter.   Quad rails still offer the most versatility and rigid means of attaching Picatinny based accessories.

While they do offer MLOK handguards (RHF, with 1913 rails on top, and MLOK at 3, 6, and 9 o'clock), a quad rail handguard is what they've always wanted.

RHF4 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 12o’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.

RHF4 incorporates Forward Controls design input: Omission of built-in QD swivel attachment points.  Some like the now common front and rear located QD sockets, they prefer the location of the front sling attachment be left to individual users.  RHF4 has KAC rail panel clip cutouts in front and back. RHF4 does not come with the TDP barrel nut, but can be added as an option.
