Spud Guns

[mikey09120]

i have one. about a ten foot barrel. 2in diameter PVC and 120 psi of pure compressed air. i use empty caulinkg tubes as bullets of mass destruction.
i plan on cutting the barel to 6in and adding a threaded thingy so i can switch diameters or make a double barrel or other stuff. i once shot water out of it and had it resting on the ground. masssive recoil. i wouldv flown back if i wouldve held the gun.
