Depends on who you send it to. Belt_Fed threaded my 15-22 and others on this Forum. You can send him the complete upper no problem.
I was going to try to have it done locally.
I can thread your barrel for $60 plus return shipping. Check out this album for a few pics of work I have done.

I have a local smith that's doing it for $45 (no shipping).
Ok. Glad you found someone. If your threading for a suppressor, you'll love it. Mine sounds like an electric staple gun with CCI Subsonics.
Done! Less than $50 ($48 and some change after tax).
Where at if you don't mind my asking?
