    It must just be a shadow.

    Nobody simply cares WHERE the ammo came from so much as WHO made it. And you were asked WHAT KIND OF AMMO earlier, but you didn't respond to that inquiry.

    Welcome to the forum.

    Bad ammo is my guess based on the several other guns i examined with similar results. You can probably search the forum and see them.

    Welcome to the forum.
    I'm not here to argue but I answered all questions pertaining to the ammo. I didn't know what it was at first because it was a mix of two brands. I thought the case was ejected but upon removal of the bolt I found out it was still there.

    I received my new stripped upper today and I was reassembling the pieces and I found out that a round did go off out of battery. There is a concave dimple inside where the lugs are located and the barrel shank has a convex dimple protruding from it. Some crazy stuff must have happened for this to happen. Any ideas?

    If a round fires out of battery, wouldn't it become a blowback? I would think the case, bolt etc would get pushed back. Even if lugs only partially engaged that should be able to be seen. Unless it's a slamfire, it's impossible on most ars.

    I'm just going to say it was a horrible case of bad luck and move on. I found the same barrel I had before on clearance at Midway.

    So as the bolt starts to retract the firing pin moves rearward?

    As the bolt is going through the locking process, the firing pin stop shelf transitions from the carrier, to the tail of the bolt. An AR-15 should be almost at full lock (Full rotation) before sufficient protrusion of the firing pin is possible.
