    URXII loose. How do I tighten it?

    My URXII rail has begun rotating about 1/4" to the right, which throws off my irons. I can't see any way to re-tighten it, however. For the moment, I've moved my optic mount ahead one rail space to hold the forearm from rotating, and it seems to work, but I'd rather fix the problem itself.

    You should stop shooting it, the barrel will also be loose.

    Is it a KAC rifle or did you have a shop install the rail on your rifle? You need special tools to install it correctly, it's not something you can fix at home.

    Needs to be fixed. Barrel nuts are one time use so you need a new one, and have it redone.




    Don't shoot it that condition because the barrel is going to be loose, too.

    The KAC URX rail is expensive and the wrench to install is as well. I implore you to contact KAC and see if they can fix it or recommend someone. If you take it to the local butcher you risk ending up with hamburger meat and not prime rib.

    First time I've heard of this happening. Is this a KAC rifle or a upper built up with a URX? If so, who installed it?

    I had one loosen up on me. Not a factory KAC gun but was put together by an at the time KAC employee on his own.



    Yes it needs to go to someone who knows what they are doing. I recommend either Gun Gallery in FL, MSTN or Lawmens Shooter Supply. All have the tools and experience to get this fixed. If its a factory gun contact KAC.

    The URX II is not rotation limited and you're on your way to a dangerous situation. Do NOT have someone local try to work on it unless they install and uninstall URX rails regularly since the barrel nut is a proprietary part and needs the $200 or $250 wrench to work on it.

    This is part of the reason I traded one of my SR15's and why I ordered a RIS II to replace the URX II on my remaining sr15. Something like that happens while on a trip or during a class, it's most likely not going to be fixed until it's sent somewhere unlike a standard rail and barrel nut.

    By any chance did you have the muzzle device replaced?

    Casey is now a KAC employee. I believe the new Lawmen's contact is Troy.

    Here's hoping Troy is just as helpful.
