Was there an indentation on the primer? If the case was unsupported and went off it seems that rupture would be larger than an 1/8". How did he describe the spent case in the chamber, was it normal?

He had a ruptured case and the gas blew out the mag. That's how it's supposed to work.
Most of the comments here say that this is a ruptured case. Maybe that is what happened; there also could have been a sharp thing in the mag ( I dont know ) that may have hit the primer....
An AR cannot fire out of battery. The hammer cannot strike the firing pin, and out of battery means the firing pin cannot protrude through the bolt face and contact the primer.

Well, now it sounds like a slam fire? Could the primer have blown out and caused this?
But he's saying that the round in the chamber was unfired.
OP, was there a ruptured case at all as a result of the mag blowing? An 1/8" slit near the ejection groove of the case from the mag doesn't seem sufficient to cause what is being described.
And in the end we're probably never going to know what really happened. If a cartridge actually was detonated IN the mag, it's the first one I've ever heard of.
Maybe the round in the mag with the split case had the split case already before the incident. Real shitty reload. So it was spilling powder everywhere or at least had exposed powder. Sometimes some Sparks and flame get into the upper receiver while firing. This could set off this round with little damage to anything.
Without pics it's all just speculation, but this is the only way that a round going off in the mag seems possible. There is no way a round cooks off in an ar mag, that is ridiculous.
