Is This The World's Largest Nerf Gun?

Have you ever been involved in a Nerf dart gun battle and thought to yourself, "I need more power"? 

YouTube user Mark Rober did and so he got together with some friends and they did more than just increase the power, they increased everything. 

The gun is powered by a 3000 psi paintball tank, but the pressure is regulated down to 80 psi to shoot the dart.

It is not official yet, but this just might be the world's largest Nerf gun in existence! 

Check out the video below demonstrating how the finished gun shoots in some tests of distance and accuracy.
