Why would I need a 1/2x28 to 5/8 adapter? Any suppressor I buy uses a mount that is available in any thread down to 1/2x28.Like you said, find a better gunsmith. Mine added a flared collar to mine so no not sub par adapters or ugly muzzle attachment devices. Just direct thread 5/8x24, it’s awesome, no compromises, those little 1/2x28 to 5/8x24 adapters suck.
Anyway, this is pedantic.
If you need a 5/8x24 adapter (nut) just buy one. If it threads on smoothly, use it. If it doesn't throw it in the trash.
