Looking to put a FH on the end of this barrel.  Its .624" in diameter at the end of the barrel.  I like this barrel its lightweight under the handguards and it shoots well.   Who would be a good person to do this work?  I don't think I trust any of my local area gunsmiths.  I've threaded a barrel for several FAL rifles in the past but I've never done an AR barrel.

Here is a pic of the barrel:

ADCO does a great job, and turn-around time is FAST.
