The KAC Rifle Length Free Float RAS (Rail Adapter System) features full length mil-spec M1913 Picatinny rails at the 12-, 3-, 6-, and 9 o’clock positions, making it compatible with any number of rail-mounted tactical accessories. The rail free floats the barrel, allowing for consistent barrel harmonics upon firing, and thus increased accuracy potential. Includes three KAC 11 Rib Rail Panels. This fore end uses a proprietary barrel nut that may be installed using a standard AR-15 armorer’s barrel nut wrench (sold separately). For Mk12 Mod 1 and M4 Recce platforms.
