Suppressor thread question

[longshot]

If the tidying up of the thread doesn't work and the barrel needs to be shortened due to a rethread, then would you be willing to cut the stock forend back and then remold with something like Selleys Knead It? (cheaper than a new barrel and can look alright with a paint).

I did think about that scenario, if it was wood or plastic I probably would have just gone down that path and never worried about even starting this thread, it’s a cf stock that was a right place at the right time with the right amount of money sort of purchase and I don’t know what cf is like to cut or re finish.
If there is a risk of new barrel required I will send it back to the people who originally did the work as they can fit a new barrel if the re-thread goes awry, but if there is little to know risk in getting it re-threaded locally I may take a punt.
