What is the best way to get the barrel on my USC threaded? My Gunsmith said there may be some metal tolerance issues.:780:

Ed @ HDPS can do the work, most gunsmiths should be able to do the job.

My Gunsmith said there may be some metal tolerance issues.

??? I have no idea what he it talking about... unless you wanted it threaded for some very large thread diameter where there was just barely enough diameter on the barrel to accommodate.

My gunsmith is very conservative and he is a little concerned about turning my German barrel on this thing. If I send the barrel off, is it easy to disassemble it from the rifle?

Turn down the end on a lathe, rethread to desired flavor. Probably the easiest barrel to remove and do this with.

you are not held to that exact length.

Take the ar-15 lower example. I register a lower and put the 12" upper on it. Next week I buy a 9" upper. I don't have to change any paperwork to install the 9.

Like everything with the BATF I have heard the same thing...and I have heard different things. The most popular is that you can go up in length...but not down.

Glad you're going with ADCO. I tried to contact Ed at HDPS, what a waste of time. He doesnt answer emails, only sends templates to sell is his 'combo'.
