I saw this on another forum, Apparently the lady that had it explode in her hand commented on it, something along the lines of that particular rifle jamming on the 7th round or something along those lines, so she didn't think anything of just fixing the stoppage, long story short it ended up being an out of battery fire. She claimed to be alright besides her hand and arm being very bruised. Then again its the internet so what I read could be wrong too.
