I've never messed about with Carbine barreling, just general repair, as I never had much interest in the little guys, not my forte.

Parts trader friend is building one from a partially completed receiver he found somewhere and barrel blank and wondered out loud to me in an email I just fielded as to the best way to fit up a barrel to the receiver.

I reckon, turn shank...thread & shoulder a blank and fit it up, then cut the chamber and headspace the little guy just like most everything else in thread barrel into receiver land and make any other needed cuts in the barrel after that. Seems the most economical use of time and I don't see any complicating factors. He referenced timing of the machine, but since the barrel blank he has doesn't have sights on it yet or any other cuts related to a need for indexing, I can't see any indexing issues re barrel shank thread cutting and shouldering of the barrel. Am I missing something here?

Thanks,
PM

You are on track; you will need to fit/make a piston housing as well, then drill the gas port. Easiest way is to get a de-milled barrel and use the rear part and sleeve that. Much easier than milling all the contours, slide rails, and pistol housing.
