CO2 canister discharge for arm mounted gun?
With that said, the arm cannon/crossbow thing (sorry, I sadly never played the game!) is one I'm playing with now, and I got to thinking about taking a simple CO2 powered airsoft gun, and modding the barrel to take softer projectiles, and to be mounted to someones wrist.
The question being: would the discharge from a CO2 cartridge harm someones hand? There will be leather between gun and wrist, by the way.
