Knights Armament Company Titusville RAS M4 Canadian quad rail assembly.

-New old stock

The KAC Canadian M4 RAS (Rail Adapter System) was developed for use on the Canadian military’s C8 assault rifle. It differs from the US military M4 RAS in that both the top and bottom rail sections lock to the barrel nut via a clamp and screw arrangement, making for a more stable and secure system overall. This non-free float handguard is a drop-in upgrade that features M1913 Picatinny Rails along its entire length, making it compatible with any number of rail-mounted tactical accessories.

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.
