Can the the Romanian threads be turned down to 14x1? I'm asking because I have a pinned and welded muzzle device on a Wasr 2. I want to un-neuter the rifle. There were threads under the original barrel but, but because I was in a communist state at the time, I had a 22mm 74 Brake pinned and welded. Would it be best to leave or can it be un-neutered?
