At Airgun Warehouse we love to see people think outside the box. Genuine Airsoft cannons are far and few between so when a couple of guys get together and figure out a way to make on on their own, we stand up and salute their American ingenuity. STARTAirsoft780, a Youtube user posted the below video claiming they built an Airsoft cannon for around $20.00. As always, even Airsoft can become dangerous especially when building your own equipment. We never want anyone to get hurt. It’s important to understand that these guys have understanding on how compressed air works and they followed precautions to make sure everyone was safe. If you do not have the aptitude to do this, leave it up to someone who does.
