Sounds to me as if the round was chambered far enough so that the firing mechanism would function but was not fully chambered resulting in a out of battery firing. Happened to me on a Rem 597 22 rf. Big butt surprise.
Did you check the barrel for obstructions? It sounds to me like you had a squib round. The barrel doesn't appear to be split but I am curious if there is a round still trapped in there.
Now that is good service. Good to know that they will take care of you.He said that even if the failure was ammo related that they would take care of any damages that might have occurred to the gun.
I was very impressed with the professionalism and courtesy of the person I talked to at DD. He apologized over and over for what happened and assured me that they would take care of any problems with the gun and make sure I got it back in safe working condition.
I told him that I believed the gun fired out of battery and that the mag exploded out the bottom.
I don't believe your gun fired out of battery.
I am familiar with slamfires in AR's. Unlike M1's and M1a's, which will slamfire out of battery, all slamfires I have heard of, or seen were in battery.
The AR bolt retracts when it goes into battery. Unless your firing pin is abnormally long, it will not be long enough to touch the primer until the lugs are engaged.
Your case failed while the bolt was locked, and it was due to high pressure.
If it had fired while out of battery, I expect that bolt would have knocked the buffer through the buttplate.
The more I think about it the more I think you are right. I think the scenario you're describing makes a lot more sense. When you look at the whole picture the conclusion that it fired out of battery just doesn't seem to explain everything.I don't believe your gun fired out of battery.

Yep, I retract my previous statement. Seeing the bulge at the base of the brass led me to believe that a OOB event was responsible. in hindsight that is not necessarily the case, or even likely the case, as the receiver is seemingly intact. I think a squib was the culprit. This led to a blocked, or partially blocked barrel, unfortunately plugged past the gas block, thus allowing the action to cycle and chamber the round that damaged the rifle. The overpressure caused the case to split, and the timing to be off, creating the bulge at the base of the case (there was still high pressure when the action opened). That being said, make sure that they (or you) check that barrel for bulges.When you look at the whole picture the conclusion that it fired out of battery just doesn't seem to explain everything.
Have the entire gun checked out by a gunsmith who specializes in ARs before you even think about chambering another round in that rifle!
