Besides just being completely unsafe, this shows a complete lack of knowledge about how a firearm works. What in the hell is "looking down the barrel" going to tell you about why a firearm mal-funtioned. "hangfire." I'll give you a hint, nothing.
If this is real, I hope that this person never touches a gun again, or at least until he has the knowledge of all safety rules and how a gun works, so he can correctly fix any problem he is having with it.
