They will not warranty this out because it is not DESIGNED to be removed SAY WHAT .They gave me some other BULL SHIT about it being a Kar flasher suppressor and they have no control over it. GIVE me a FING brake.Was buying a lot of stuff from them .
Thank you for your comments.
The flash can on that upper is aluminum. It is designed to move the flash out from under the rail on the short barrel. Re installing the aluminum can on a steel barrel needs to be done with care. You have stated here that the can was securely affixed when you received it, and test fired it. If it will not tighten down now, something must have happened to it in the re-install. The workmanship responsibility is assumed by whoever last assembled the item in question. If the threads on the barrel are unaffected, the issue is with the can. This is something that would not usually be covered under warranty.
If you remove the stock intake on your new Mustang to fit a new high volume intake for a few passes at the strip, and then the bolts don't tighten when re-installing the stock intake, it is not likely to be covered under warranty by Ford - it left the factory with those bolts tight. Yes, people modify their cars all the time, however, the modifier assumes responsibility for the changes.
We apologize for the inconvenience.
