Knight’s Armament URX 4 Rail, M-LOK 10.75″

KAC PN 32304-1075

The KAC URX 4 Forend 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. It is also 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. 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.

Each URX 4 Rail comes complete with an installation wrench, shim kit and instructions

Weight: 10.2oz
Length: 10.75″
Inside Dia: 1.55″

    The one piece design is what I love about this handguard. Once in place it does not move. And since it’s a kac there were no defects and a great finish. Great for any sbr or pistol.
