Knight's Armament Company (KAC) URX 4 AR-15 M-LOK Handguard - 8.5"

AR-15 Handguard


Knights Armament Company URX 4 8.5" M-LOK Forend Assembly Kit is a fully modular design that utilizes the revolutionary M-LOK accessory mounting system. The URX 4 Rail is stronger and more stable than previous URX designs due to its one-piece construction. The IBN system allows the rail itself to act as the barrel nut when torqued onto the rifle, completely eliminating the need for a separate steel barrel nut. M-LOK accessories may be mounted anywhere along the URX 4's length, making it one of the most user configurable designs on the market.
