I live in B-Spa/saratoga but work in and around albany/schenectady/amsterdamn depending on what I’m doing that day.
If you just bring me the upper(or barrels) and the new brakes $20 each for pre-threaded barrels to swap everything and pin/weld.
I don’t thread the barrels myself as it’s too complicated to do the right way on my equipment(dead rotational alignment using no shims/washers). Better to send out if the barrel needs threading.
