A young man testing a bulletproof vest accidentally killed himself when he fired a shot into his stomach at point-blank range.

Shocking footage shows the man firing a bullet into the vest and then dropping to his knees in pain.

He throws the handgun to the ground and holds his left hand to his stomach, as a worried pal asks: "F***, are you dying? Are you really wounded, bro?"

The wounded man doesn't say anything as he takes off the vest - said to be the same kind of armour worn by Russian special forces - and collapses on the floor.
