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

Yea, it’s a KAC URX 4 handguard, it’s sturdy, it’s great, light. But folks, lemme tell ya about the sense of humor these fine people have. First, Senior Sweatshop worker Mike picked the items for me, presumably in a non-air conditioned, stuffy, humid warehouse somewhere in Arkansas. Next, and they really went above and beyond here, they sent me thing of Chicken Ramen with my order. Now that’s class people. How did they know that was my favorite?

I’ve been through so many handguards at this point …lots of legit choices, but this one totally does it for me. Totally solid and comfortable. Looks awesome. Easy enough install for me (ymmv). Very happy with this purchase. Rooftop is awesome too.

Sturdy Mlok rail traded out my bendy boi mk16 rail after it failed on me. Can’t beat it, the install is durable as well sold fit to a MUR upper with Shims. On the plus side I got a free dinner from Abbie with Rooftop Defense. You can’t beat the service and good humor
