This is not the best way to test body armor.
These guys just want to make sure their body armor does what it should. The logical way to test it is to hang the armor on a target holder and then shoot.
However, these guys decide to take the bullet themselves.
These guys think they have their safety concerns covered. The target is wearing safety glasses, ear muffs, and a body armor vest. What could possibly go wrong?
The AK47 rifle hits the vest pretty hard. The guy wearing definitely felt it and probably ended up with some bruises.
As far as we know, the test subjects were not harmed during filming. This scenario could have had a very bad outcome.
Do not try this at home!
