Karcher Gun Replacement

[Badboyztn]

I know this may be an odd question, but has anyone successfully swapped and the gun included with their Karcher electric pressure washer? Specifically the X series? I have the 5.540 and would like to use the gun included with my AR 390SS, but I can't find any adapters anywhere that will allow that.

If you have a good hardware store you can bring the stuff down there and let them help you, maybe even Home Depot or Lowe's if you get the right guy.
