Interesting.
Having personally blown up an AR with a 300,000+ psi load--my observation has been the extractor and it's slot in the bolt are a primary conduit for vaporized metal and high-pressure gasses out the bottom of the carrier (which can also fail and blow off) and down the mag well--blowing up your magazine in the process--but otherwise keeping the upper receiver and the shooter intact.
