Kernel, I just always figured that there would be normal manufacturing problems, like you never buy a car made on Monday or Friday and the "third-shift" anomalies that happen in almost every manufacturing situation, would rear its ugly head. I just assumed that every thing had to be smoothed out and double checked and fitted before everything was tightened up.
Now I realize I have no idea the order of the manufacturing step with say the AR barrel, but are you saying its impossible to receive a barrel with the threads out of phase? Cool, if true.
Which threads? The muzzle threads are not timed, that is why the A2 flash suppressors used peel washers to clock the slots properly. The rear threads for the bbl extension may be timed, I never checked them as all the bbl's I have used already had the extension installed. They were all correct. I would assume the easiest way to manufacture one would be to install the extension and then use it to index the bbl in a drilling fixture for the gas port and locating pin hole. Less labor and scrap that way.

We replaced those with Colt branded replacements and had no issues after.
Can a maker produce a "bad" AR15 part that doesn't work without fitting or modification? Sure, no one's perfect. But it is the exception rather than the rule, and personally I would return it for a replacement if it was out of spec to the point it took more than a minute or two of fitting. I did run into this issue just a few months ago assembling a friend's new AR, he had purchased a cheap imported M4 style stock and the buffer tube wouldn't thread into the receiver more than a couple turns before stopping. He exchanged it for a US made one that screwed in with no issues. Could I have lapped them together? Sure, and then an hour later he would have a receiver with loose threads if he ever changed the buffer tube, and the anodizing would have been gone. Here at the auto shop I work at, we replace a fair number of axles on front wheel drive cars. Every brand we've tried, some come in with the splines smashed from getting knocked around in transit. Now, I could grab a file and redo those splines to make them fit, but why? The parts store simply sends out another one and I don't spend $30 worth of shop time fixing something that should be right in the first place.
Good Man kernel.. Where were you when me and my Marine Gunny Bro were trying to figure how to put the damn bolt and charging handle in.. 25 years in the Marines, I just started at him in amazement..
We finally figured it out when we sobered up in the morning..
assemble/ build --who gives a flying F%&c anyway?
when dug herbert calles an engine a "motor" are you going to go around correcting HIM? man has been running top fuel for decades-- his dad chet has been in the roller cam biz since the early 1950s , when dug was a kid i think he had 50w racing oil in his baby formula!
how about mongo? your going to tell mongo -- hey you didn't build that ar-15--!!! you just assembled it!--
ya better hope mongo is having a good day that day-- LOL!
if mongo snaps a upper and lower into an ar-15 he can say he built it as far as i am concerned. LOL!
That is amazing man. Beautiful.
