Yes. Pin became a straight piece of metal. That's what the bolt did to itThat one I threw away. This second one still seems serviceable. I hammered it back into shape.
Well maybe a bit more information about my stoppage. It was actually two stoppages. I had one stoppage where I fired and the bolt froze forward. I went off range and freed it (not noticing if the retainer was still there or not. I was just happy to free it). The RO told me to try it again so I went to the line and fired once and it jammed again. That's when the RO shut me down and we tried to free it. I took down the lower and then pulled the bolt out and found the cotter pin in the barrel.
The first stoppage happened after maybe 30 rounds. Is it possible to fire that much without the retainer pin properly in?
I can tell you after this I will make sure that I check the pin is held by the retainer.
I don't really know, mine wouldn't fire but It was all i could think of.
