Recently I got back into Nerf with the advent of the Vulcan. One of my friends got one, and it all went crazy after that. Now our arsenal includes 9 magstrikes, 1 longshot, 1 recon, 2 vulcans, and my trusty lock and load.
We also got our hands on an electric shopping cart and it's currently being "uparmored" with cardboard. Knowing that I'd have to defeat this shopping cart o doom, I set about creating a bazooka.
My Vulcan is next to it for a size reference.
"Cartridge" and mini nerf football "rocket."

Cartridge locked in place, rear cover open.
The barrel is 2" PVC, the receiver is made from a 2" PVC coupler with locking lug recesses cut into it. I nested it within a 3" ABS pipe by heating quartered 1/2" PVC with a torch and rolling it around with a 2" coupler to flatten and shape it so it would fit snugly.
The "cartridge" is made of (from left to right in the 2nd pic):
2" to 1" bushing
screws with cut heads for lucking lugs
2" to 1" bushing
2" PVC expansion chamber
1/4" NPT male fitting with a female/female coupler screwed onto it from the inside
Currently it runs off of my air compressor, but the parts to run it off of Co2 cartridges are coming in the mail. Using a piece of packing tape inside the coupler has reliably fired the bazooka at 90-100 PSI. Range is unknown, as I've only fired it in my garage. Paint is Rustoleum Camo Khaki, Rustoleum Camo Brown, and Krylon flat black.
The ideal projectile for it is the Nerf vortex pocket football, but it will also shoot ballistic balls.
It's my first "home made" so I'll have my flame shield ready.
