Suppressor thread question

[Hermitage]

It’s looking more and more like that is the situation.
I take it you understand the finer points of cutting threads, my own personal experience starts and ends with using tapping dies, what I am interested to know is whether it is a fairly straight forward process to tidy up a thread or is there some significant risk the thread could end up wrecked in the process and need to be cut off and started again.

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.
