The KAC URX 4 Rail 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.

    Amazing handguard. Super comfortable feel, KAC quality for sure. Was one of the more difficult installs I have done. I had to get creative while installing the gas block on a 11.5 noveske barrel. Final product was worth all the cussing.
