Do airsoft guns hurt?
I can tell you it does.
I participated to Operation Cameleon Death of Quick Pass on July 21/07. I received three rounds in my face from a distance of approximately 30'.
One splitted the left corner of my lower lip sending gushing blood into my mouth. The other splitted my skin, below my mouth, producing slight bleeding. The last one lodged itself between my skin and by muscle, below my mouth, near my chin. I required surgery at the hospital to remove it.
