Out Of Battery Detonation AR

[moajoe]

I something similar a few years ago. It appears that the case head flowed back into the ejector hole. It's called a "flashover". This is the result of a light powder charge where the powder lays throughout the case sort of like laying a 2 liter soda bottle on its side with one liter of fluid. The theory is that when the primer is ignited it does not burn from the back of the case forward but ignites all of the power at once causing an overpressure.

I like your thinking

. Very plausible. A few people forget about the dangers of a lite charge allowing detonation.

The OP has really appreciated all the info.
He is gone 24 hours. Maybe not so bad these days.

I know everyone is busy but after a few weeks and 12 pages of responses maybe he should take a minute.

had the same thing happen to me I don't care for the ar 15no way should a firearm do this but it did

So the AR-15 design is faulty even though literally millions of rounds have been fired through them?

Interesting perspective. I'll leave it at that.
