Suppressor thread adaptors

[Friwi]

Any competent fitter and turner should be able to make one it’s just an internal and external thread
The question will be if you have enough meat between the sizes

You are dead right with that one:
The female thread in 14x1 is going to be a tiny bit more than 14mm diameter .
The male 5/8-24 will have a bottom grove around 14.88.
That leaves less than 0.44mm of thickness of material. Definitely not ideal if the two threads are on top of each others.
