Just keep the law in mind- you don't want to run afoul of the BATF and end up in federal prison.
A "machinist" can certainly do the work for you if they're experienced- but they have to do it while you're there (meaning local, obviously) if they are not a licensed as a gunsmith by the BATF. Receivers can only be left overnight with licensed smiths.
Anytime you ship a firearm (the serial-numbered receiver), it must go to a gunsmith.
My C&R certainly doesn't make me an expert in these laws- but that's my understanding...suggest you research the law yourself if you're considering having the work done by anyone other than a gunsmith.
There are a few threads floating around on this forum, and others re: the UK-59 barrel. I considered it myself until I fully realized all the work involved. It's an interesting project, just be sure you know what you're getting into.
The barrels are very wide at the receiver- 1-1/2" if I recall correctly- probably making them too wide to fit the MN stock or an aftermarket like Boyd's. From what I've seen, the barrel also needs to be profiled the entire length down to a smaller diameter that will fit the stock.
Good luck, and be sure to share the results!
