Knights RAS 7″ Drop-In AR15/M4 Carbine Length Quad Rail

Description:

The Knights Armament M4 RAS (Rail Adapter System) was developed for use on US military M4 Carbines utilized a 14.5 or 16″ barrel. With over 1 million rails issued to date, it is one of the most battle proven designs available for the AR15 platform. This handguard is a simple-to-install, drop-in upgrade that features genuine Mil-Spec M1913 Picatinny Rails along its entire length. What sets the M4 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.

The KAC M4 RAS 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 AR15/SR15 based platforms only; not compatible with SR-25 variants.
