No injuries. My left hand was numb for 1/2 hr and the adrenaline was crazy. Glad I was wearing Mechanix gloves and glasses.
It was a Norinco CQ. 14.5" bought this fall and Norinco white box ammo.
Loaded the mags at the range from the package. Brought the rifle out of the bag, chamber check, put in a pmag, pulled the charging handle hit the safety and let 'er rip.
Fourth shot into the first magazine and it happened.
Blew everything out the magwell and the bolt is stuck shut, no live ammo left in the chamber. What I can see of the bolt face and extractor are pretty messed up as well as the walls of the bolt carrier chamber. Did not blow apart the upper but distorted the metal. It is junk now. Lower seems okay.
Apparently this is rare and I am very lucky.
I am trying to narrow down what happened. The rifle was clean and oiled properly. Bolt group was assembled properly. Function check proved operation after cleaning. 4th round in makes me believe there was no barrel obstruction. Rifle will not fire if bolt does not lock up. Firing pin will not protrude unless bolt is locked up. Trigger group functions correctly. other ammo primers look okay.
Only conclusions I can figure are:
debris on bolt face such as broken extractor or broken locking lug?
Shell casing stuck in bolt face, bolt tried to load new shell, old casing struck primer of live round?
Bolt did not lock up properly due to debris in locking lugs?
Parts out of spec?
So either a failure to extract or a detonation out of battery is the result. Caused by my own stupidity or a total failure of rifle or ammunition.
I will post pics after I create a photo bucket account.
Has this happened to anyone else?
Does anyone have any ideas what happened?
