That's what I'm looking for myself.Links, and more specific info related to PSA please? Thank you
Especially with machinery.BLUF
You normally get what you pay for.
Someone had posted the article a few months back. This may be why they are being extra cautious these days.
Think it was even more specific to the ammo They where using too.I believe that was over a Rock Island Armory pump shotgun.
I have read concentricity issues are fairly common with AKs.That's what I'm looking for myself.
I mean, who would thread barrels and send then knowingly to the public with issues like that?
FTFYYou normally get the Quality Control you pay for.
This would explain my experience with PSA that’s detailed in the AR tier chart thread.
I know in the Army the amours had a machined rod that if you put it in the barrel it was good. If not it was bent or out of spec.
They also used gauges for barrel, chamber, ect.
Seems like a manufacturer would do that?
Its also being prudent to have the correct size drill stock in house on you bench to check when one adds a suppressor along with a quick release mount and a suppressor.This would explain my experience with PSA that’s detailed in the AR tier chart thread.

Yep, it may work just fine until another part that's at the far end of it's tolerance range makes it go kaput.I'm sure they do. Likely multiple times. Last thing any manufacture needs is bad press like this.
Like car manufactures with recalls though, stuff goes wrong. Humans do the measuring and we are flawed. I have seen auditors measure a part a full revolution of a dial gage and pass many, until a another auditor catches the error.
A lot more stuff goes wrong than is known, I'm sure you have heard of recalls that have never made it to the recall stage. I have actually seen an auto parts contractor catch a part out of spec, after days of production. Tens, if not hundreds of thousands of dollars worth of out of spec parts were "worked into" containers of parts that were in spec.
The other side of the coin is that frequently a minor out of spec part still does the job just fine. You wouldn't know, if you didn't know.
Another aspect is the legal stuff. What once was, "We're sorry, here's a replacement," now involves class action lawsuits, personal injury attorneys and all the CYA associated with them.
