Did Colt say re indexing or re-qualify? It a barrel goes past about 10;30-11:00 oclock with hand tightening only, then the rear of the shoulder can be milled off and the forcing cone can be shorten until it will tighten correctly going in another whole turn. They will also cut the correct forcing cone angle. Colt has the tools and knowledge to do it. Of course this should have never left the factory but it happened. Wait and have it repaired correctly. That is what I would do.
