The guy in the pic above apparently had his face destroyed when an FN FAL 7.62 assault rifle he was testing out blew up in his hands.
According to the info I got, the incident happened in a Brazilian favela, so I’d presume the guy is a local drug dealer. The video below alleges to show the moment the rifle exploded, and a piece of it struck his face.
I don’t have sufficient knowledge about guns to understand what the hack happened. Perhaps someone with adequate knowledge can fill us in on what were wrong and what t he guy should have done to avoid getting his face mashed up?
Props to Best Gore member @otrium for the video:
