KAC URX4 Free-Float Forend

The Knights Armament URX 4 Handguard with aluminum construction; 13” M-Lok mounting system; black anodized finish; and 1.55"/1.68" inside/outside diameter.

Now for sale at Mister Guns is the KAC URX 4 AR-15 Forend Kit offered in a fully modular design that utilizes the revolutionary M-LOK accessory mounting system.

Due to its one-piece construction, the URX 4 Rail is stronger and more stable than previous URX designs, as well as lighter due to its Integral Barrel Nut (IBN) system of attachment. 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.

Boasting one of the most user configurable designs on the market, the KAC URX4 handguard with negative space mounting points allows you to mount M-LOK accessories anywhere along its length. The package includes an installation wrench, shim kit and instructions.
