KAC M5 RIFLE RAIL ADAPTER SYSTEM 556

Knights Armament Company M5 Rifle Rail Adapter System w/3 11-Rib Panels, 1913 Picatinny, Black 98065

Knights Armament's M5 RAS (Rail Adapter System) was developed for use on the US military's M16A4 and with hundreds of thousands of rails issued to date it is one of the most battle proven designs available for the AR-15 platform. This non-free float handguard is a simple-to-install drop-in upgrade that features genuine Mil-Spec M1913 Picatinny Rails along its entire length. What sets the M5 RAS apart from other 2-piece quad rails on the market is that it securely locks to the rifle's barrel nut via a clamp and screw arrangement making it a very solid foundation upon which to mount tactical accessories. Includes three KAC 11 Rib Rail Panels. The M5 RAS is a drop-in replacement part for standard 2-piece polymer A2-type handguards. The rifle must have a rifle length gas system delta ring assembly fixed front sight/gas block and either a round or triangular handguard end cap. Lighter barrel profiles work best (Government contours). Heavier barrel contours may require modification to the inside of the rail. For AR-15/SR-15 based platforms only
