We have long been fans of the classic KAC RAS since the early 2000s. Throughout the years, we've seen trends for lighter, small diameter, and rails-only-where-you-want-them hand guards, this was before the advent of Keymod and MLOK. Then quad rail made a comeback. We 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 our opinion, practical and durable designs are always useful, regardless of which way the wind blows.

• We've stayed with hand guards with 1913 rails in four quadrant for their versatility, and we weren't concerned with the then popular, now less popular ways of using the support hand to grasping the hand guard, which called for their being of smaller diameter. Quad rails still offer the most versatility and rigid means of attaching Picatinny based accessories.
• While we do offer MLOK hand guards (RHF, with 1913 rails on top, and MLOK at 3, 6, and 9 o'clock), a quad rail hand guard is what we've always wanted.
• RHF4 comes in two lengths, 11.5" and 9.5", it is a quad rail hand guard 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, we prefer the location of the front sling attachment be left to individual users. A QD swivel can be ordered with RHF4 as an option. The rail numbers are machine engraved, and a subdued Cygnus is engraved on the right side of the RHF4.
• RHF4 has KAC rail panel clip cutouts in front and back.
