The 45 RAS(Rail Adapter System) was developed for the US Military's M4 Carbine with hundreds of thousands issued to date. This battle proven design utilizes a drop-in install and features M1913 rails on all sides. This 2-piece design is securely locked into place via the barrel nut clamp and screw assembly. This rail offers a rock solid foundation for rail mounted accessories. Includes three 11 rib rail panels.

Rifle Requirements: The 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 AR-15/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions are included.
