The Knights Armament Company URX 3.1 for AR-15s in 5.56mm is a free floating continuous top-rail handguard system that uses short sections of Picatinny rail on the sides at the front and rear ends for mounting tactical accessories, eliminating the commonly unused sections of rail for reduced overall weight and a more comfortable grip. The handguard has a total of 4 integral QD sling swivel sockets for ambidextrous sling mounting. Additional URX 3.1 Rail Panels and rail sections allow the user to customize the forend to their needs.
This forend uses a proprietary barrel nut that MUST be installed using a KAC URX Barrel Nut Wrench (Sold Separately)
