I am planning on getting the barrels on my ARs threaded and am curious about one thing. The gunsmith I talked to locally said he does thread barrels, to include cutting a new crown, as he indexes the barrel from both ends in order to turn it down and this messes up the crown. Will turning the crown have any negative effect on the chrome lining of the barrels? Any information regarding this procedure would be appreciated. Thanks in advance.

It depends on how he intends to cut the crown.  But if done properly, there's really no reason why the barrel should have to be recrowned in the first place.  You might want to try talking to someone like ADCO who does this work all day long and knows how to do it right.

There is absolutely no reason why the crown should be touched for barrel threading.  I'd either get a clearer explanation as to what he is doing or get a new 'smith to do the work.

+1  There is no need to mess with the crown when threading the barrel for a FH.  Sounds like you need to talk to ADCO or Kurt's. (Both found here in the Industry section)

The guys at ADCO do the threading on a mill.  Upper disassembly is not required.  Wish I could find the thread where they stated that, but I can't right now.

I ship all my threading work to www.socommfg.com

Ernie does great work, he has threaded several barrels for me.

Buy one of his side charging uppers while you are at it.

+1 here for Kurt's (I haven't worked with ADCO, yet). Kurt has done some work for me and it is great. Frankly, I have come to the realization that there are very few gunsmiths, that operate independently, in the US qualified to do the quality work that we demand for our ARs. I think that most of the better gunsmiths work for the big names (colt, bushy, arma, etc..), do not take on new customers, do not advertise, or otherwise do not hold themselves out to general public.

Copy that, will look for new smith to do the work. I kind of wondered when he talked about the crown, it seemed wrong to mess with the chrome lined barrel / crown.
