I want the plans for this. Automatic crossbow

I think this guy has been talked about before, but I don’t remember seeing this crossbow. He starts shooting the crossbow around 1:27

No one needs a crossbow that fires more than 1 shot with the pull of a trigger.

That is super cool. I wish he was my neighbor. Think of the fun I would have.
