KAC-Knight's Armament AR-15 RAS II Free Float Handguard (22243-1)

The KAC Free Float RAS II (Rail Adapter System) is a unique variation of the US military M4 RAS handguard that enables shooters to install a free floating, quad rail forend onto their rifle without needing to disassemble the gas system or delta ring assembly. The RAS II incorporates a short, over-receiver rail section that rides over the delta ring and clamps to the upper's top rail for stabilization. In addition to securing the forend assembly in place, this short rail section is an ideal area upon which to attach a low mounted red dot optic. Includes three KAC 11 Rib Rail Panels, one KAC 6 Rib Rail Panel, and one KAC Vertical Fore Grip.

  • Length: 6.25"

Rifle Requirements: The RAS II is a drop-in replacement part for standard, 2-piece polymer, M4-type handguards. The rifle must have a carbine length gas system, delta ring assembly, fixed front sight/gas block, and round handguard end cap. Lighter barrel profiles work best (M4 or Government contours). Heavier barrel contours may require modification to the inside of the rail. For AR-15/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions are included.
