Cost Analysis: Thread post-ban AR Barrel

[2PaperTigers]

Just wanted to solicit some opinions. I have a post-ban 20 inch Colt barrel. Is it possible to cut threads for a muzzle device? What should I expect to pay for such a service, if possible? Thank you all in advance.

I thread AR barrels for $40.

That's a great price for threading a barrel and it's done right.
