The Forward Control Design RHF Hand-guard is a lightweight, free float rail system for AR-15 platforms. The RHF is machined from 6000 series extruded aluminum, its barrel nut is machined from 7075 aluminum, both are Type 3 anodized, while the rail mounting hardware is machined from 17-4 PH (patent pending).  The RHF also incorporates anti-rotation tabs.


  • Made of 6000 series extruded aluminum
  • 7075 aluminum barrel nut
  • 17-4 PH stainless steel mounting hardware
  • Type 3 anodizing
  • 1.315” internal diameter, compatible with most low profile gas blocks.
  • 1.378″ barrel nut diameter
  • 10.2 ounces total weight with mounting hardware
  • Barrel nut wrench included

Featuring M-LOK attachment slots for a multitude of accessory mounting options the hand-guard also has generous barrel cooling vents for heat dispersion/weight reduction.  The anti-rotation tabs ensure proper fit and alignment and prevent movement once installed.  A full length 1913 Picatinny rail runs along the full length of the RHF giving you the most versatility for running optics and sighting systems of your choice.

The RHF incorporates design input from Forward Controls, such changes include:

  1. Omission of QD swivel attachment points.  Location of the front sling attachment is left to individual users, recommended to use a steel QD mounting point
  2. Barrel cooling vents changed to the classic round shape.  One might say we’re paying homage to Knight’s Armament’s RAS and RIS where meaningful modular revolution began.
  3. Simplification of the already understated aesthetics of the CMT UHPR Mod 2 handguard.
Available in 15″, 13.7″, 12.8″, 11.5″,  9.5″, and 6.7″.

  1. erouse65 (verified owner)

    This rail mates well with Aero M4E1 uppers with similar finishing that gives an OEM look. They also look cleaner with the matching barrel lengths.

  2. matthew.p.murray (verified owner)

    Solid construction. Lightweight. Great sizing guide for matching with your barrel lengths.

  3. Robert Hubbard (verified owner)

    Much easier install than my BCM handguards. These will definitely be at the top of my list for any future uppers.
