KAC – URX 4 Installation & History of the Modular Rail

The URX 4 offers a full length continuous top rail and is a one-piece free float design, incorporating the open source Keymod attachment system as well as an integrated barrel nut.

The section of the original rail is also very cool for folks who’ve never seen it.
