I believe most short chambered barrels are in the neighborhood .010 - .015" shy when they are rough chambered. But I'm not a gunsmith so don't take that to the bank.
Labor is only part
of the equation though. Material cost, tooling cost, the time and expense of getting the education to be able to do the job - and do it correctly
have to be considered as well.
An armory will be extremely well equipped of course and considering the volume they have to deal with, they are going to employ the most efficient way of doing the job - whatever that is. Simply spinning on another barrel and having it line up and headspace properly is a long shot in most cases. If it doesn't work out, they can simply keep trying different barrels until they find one that works out. Which is fine, when you have a warehouse FULL of barrels to pick from. I don't think too many gunsmiths have that option available to them outside of the military.
, to do the job yourself if you were so inclined - you would need a barrel vice and receiver wrench to change the barrel out. This is assuming you don't have to do any lathe work to get the barrel to fit and clock to the receiver correctly. (Sight alignment, extractor cut position, etc.)
Finishing the chamber could be accomplished with a "pull-through" reamer, cutting fluid and a set of headspace gages. Spend some time at Brownells web site and look up the cost of those tools, and you'll get a better idea of how much the job might be worth to you then. Just one opinion.
