I am contemplating having the forward section of an AR barrel turned down; just the forward area ahead of the FSB. The barrel is Melonited (S&W bbl) so hardened if that influences someone. I was advised to ship it to ADCO in OH, but if there's someone local I'll send the business there. Since it's only the barrel to be shipped the cost of that is not the issue, just prefer a local machinist or gunsmith if practical. I'm on the Eastside of Seattle.
