Knights Armament KAC M5 Rifle RAS, 5.56, w/ 3 rail panels, new

M5 Rifle RAS Forend Assembly for M16, complete with three 11-rib RAS rails

The KAC 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.  Vertical grip is an optional add-on.

Rifle Requirements: 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; not compatible with SR-25 variants. Installation instructions are included.

This is a new M5 RAS rail.  We get them both in new part boxes and also as take-offs from full M16 rifles.  We do not differentiate, as the product is identical.  The take-offs are new and removed by Charlie's expert armorers, as we do every week with some part.
