M16 Clinic upper KABOOM (very pic heavy)
M16 Clinic upper on Colt lower. Lothar-Walther cryo .96" dia. barrel (10.5" IIRC) with YHM FF rail. Unsure of make of stripped upper or BCG.
Suspected cause was a squib load, followed by immediate action, chambering a second round. Shooter was left-handed by firing from right shoulder. Magazine puked out the bottom, case head sheared off, case stuck in barrel removed with tools after the fact. Various states of disassembly shown were achieved at the range with minimal tools. Upper was removed from lower, rod was used to pound bolt back through bore, and then a screwdriver and heavy hammer were used like a chisel to pouch the carrier back to pull the bolt out of battery.
No injuries to the shooter other than being visibly shook up.
Ammunition was shooter's own reloads.
This was in a match setting where I was the Safety Officer and the shooter was the only one on the line. I *should* have caught the squib but this was the second-to-last shot of the stage and my mind was getting ahead of me.

and remember kids, always strike the heel of the stock, not the toe, on the ground when mortaring
