Product Overview

Knights Armament M5 Rifle RAS Forend Assembly


The Knights Armament M5 Rifle RAS Forend Assembly 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 Knights Armament M5 Rifle RAS Forend Assembly 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.

    Shipping came in punctually, and the product itself was all sealed as if it came right out of the factory there were no blemishes or no issues with the product that I received whatsoever. Would definitely do business again with this company.
