    Gunsmithing Knight's Armament URX RAS

    I have seen that the Knight's Armament URX RAS will only fit on a DPMS and not an Armalite? Is there a way to do some work to get it to fit on an Armalite or is it completely out of the question? What is it on the rail system that makes it incompatable with an Armalite platform?
