Barrel threading in SFBA? (15-22)

[scootle]

Contemplating having the barrel of my 15-22 threaded since I have a spare A2 birdcage sitting around unused. Anyone in the SFBA ever get their 15-22 barrel threaded and/or have a recommendation for a good gunsmith/machine shop to do the work?

Otherwise, I'd have to ship the upper assembly off to someone farther afar to have the work done.

Thanks.
