I was not gonna post this but the people who welcomed me in my "hello world" thread encouraged me to. So here it is.
My attempt at replicating an M72 LAW launcher.

Youtube video of a buddy firing it in a parking lot.

and My instructions on how to make one

It's made out of 2" schedule 40 ABS pipe with a fiberglass shell. It shoots Nerf pocket vortex a little over 100 yards. I use it for airsoft and I have a strict minimum engagement distance rule of 100 feet. At that range the energy is dissipated enough where a person can catch the football without injury.
This is used as an "area effect" weapon. That is, it is never, ever aimed directly at a person.
