Can a threaded barrel be "unthreaded"?

[Fudgie Ghost]

Seems I may have done a dumb thing. Just sent a money order to a guy for a Bushie upper. He tells me that the flash suppressor is pinned on a threaded barrel. Well, don't you know that here in NYS, with our very own state AWB, a threaded barrel is one of the things on the "verboten" list. I had thought it was just the usual bayo lug/ suppresser-hider/folding stock. Gotta do the research. . .!

So.. . can a threaded barrel be made. . . unthreaded?

Don't worry about a pinned muzzle device. The prohibition against threaded barrels is to prevent easy exchange of muzzle devices (compensators, flash suppressors and sound suppressors). Pinning is considered a permanent installation like welding or high temp brazing. The threaded barrel only becomes evident if the compensator/flash is cut off/destroyed with a grinder.

If you want to get goofy, you could hypothesize that owning a barrel and a threading die constitutes ownership of a threaded barrel. Or ownership of a rifle and hacksaw constitutes ownership of a short barreled rifle.

Uh, yeah, but you see I need to remove the pinned suppressor so I can put on a compliant brake in it's place. . .

Hi Fudgie Ghost,
The threads can be removed with a lathe or by cutting and recrowning the barrel.
But if you use a muzzle break that threads on and then repin it and reweld the pin,you will have accomplished the same thing.

Forgot to add,
If all you want it the threads "gone" a file or the most dangerous thing in a home gunsmiths tool kit,aka a "Dremel" tool
can be used to rid yourself of the offending threads.
Crude yes,but not as crude as you likely cellmate will be!

Thanks for all your answers. This seems like one of those things that nobody cares about, but "if they want to get ya", they can say "OH, threaded barrel under this brake! Gothca!"

Unless the barrel is at minimum now, the easy thing to do would be to have the barrel cut down by that 1/2" or so, recrowned, and then machined for whatever you want to install.
