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 rifles barrel nut via a clamp and screw arrangement making it a very solid foundation upon which to mount tactical accessories.
