I'm sure Medic1 knows the story in more detail. Death by penetration of eye? Possible, but, I don't know about it being done with a plastic BB going over 400fps.
I mainly thought it would be a good topic aiming towards safety. I wouldnn't look down the barrel of a gun unless it was disassembled, out of the gun. And airsoft guns are NOT toys. They should be handled as if it were a real one.
