Knights Armament KAC M4 RAS with 3 ribbed panels
The KAC M4 RAS (Rail Adapter System) was developed for use on the US military's M4 Carbine, and with over 1 million 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 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.
Includes three KAC 11 Rib Rail Panels
