Title: Guess how this happened?
Post by: SpeedTek on February 17, 2014, 11:41:38 AM
Came off a Bushmaster Upper.  Not a quality issue.

Forging by Brass Aluminum Works (Square)

It was very bizzare. First time I seen this.

Guess how it happened!

Someone tried to remove the barrel without properly locking the receiver down?

i can't believe that a forging could shear like that
glad no one was hurt and everything else is ok

Overpressure cartridge?

that would've been the logical first guess
but speed said he's never seen it before
i am assuming he's seen overpressure before

Looks like the buffer struck it.  That would mean the upper and lower weren't being held together.

My guess would be running the thing without a buffer. But you would think if that were the case it would be pretty obvious something is wrong when you go to chamber a round and the bolt doesn't go forward on its own.

12 year old girl shooting.  somehow she was pressing down the fwd assist. it broke off the paw and lodged itself between the wall and bolt carrier!  The bolt was jammed halfway back......Lower was fine.
