Bushmaster not backing up their guns?

[The Haymaker]

Quite simply, it fired out of battery. If maintenance was not the cause, it is the ammo's fault. Why ATK/Federal hasn't been notified is a mystery.

Explain how. Please.

Did i understand this correctly. A round went off in chamber. Causing the bolt 'explode' to Which caused a round in the mag to go off? How is that possible? Would/ could the schrapnal from the bolt rupture the case, exploding the powder pushing out the bullet and primer?

I have an understanding of how an ar works but im lost here...

Whatever happened, the missing chunk of bolt went straight down and destroyed the magazine. Read my prior posts.

So, doing a little reading on "out of battery firing" (consensus from those that understand the AR=impossible) and found this on Arfcom. Quite funny in regards to this thread:

"Only if you are Maine Cartirdge Company and inspecting an AR15 which blew up from the case head failure of defective factory M855 ammunition- after which you, the company, refuse to back up your product and this user is stuck with a destroyed Bushmaster AR15.

So yes - if you're a lying POS from a basement ammunition company - sure - the AR15 "can fire out of battery".

But I'm not bitter or anything........."

Hahaha!

Was your friend using Lake city Federal factory loads, or Maine CCo reloads w/ Lake City brass??

The only way I know of that a AR can fire out of battery is to slam fire due to something on the bolt face like a broken firing pin, chunk of carbon, ect. In that case the rifle would have doubled. By design, even if the hammer drops when out of battery, the firing pin will not hit the primer.

Lake City. I just found it humorous under the circumstances to find the same type thread, same excuse, different ammo.

There's no doubling here. The bolt is fully forward and bound in place by all the warped metal, another reason I doubt it fired out of battery for any reason. If he decides to get out the one handled ballpeen adjustment tool and attempt to split the upper and lower, I'll get more pictures of the bolt face and last shell fired.

Has he, or is he going to contact Federal? He should do so before doing a post mortem. They may want the gun. Besides the front sight, the rest is just about distroyed anyway.

That I do not know. Yeah, upper and lower are both either distorted or fractured. Even the magwell is bowed out 1/8".

Is the ammo real Lake City or was it Lake City ammo that was demilled into components and then reassembled at another company? If it was the later, the round is basically a hand load and the round may have been double charged or maybe the bullet compressed the powder.
