120' Bazooka Powered Longshot

Step 13: The Barrel

The most important part of this gun is the barrel. It needs to be able to slide through the front part of the gun without too much friction, but at the same time there needs to be enough pressure so the barrel doesn't fall out. I've tried different 1/2" pvc pipes but some are tighter than others. It's just the way they are. 

At my local Home Depot, they conveniently cut approximately 2' segments of pvc pipe, so i grabbed a few to have a few different barrel lengths. the one that I have in the gun right now is a little longer at around 27". 

At the end of the barrel, I have a 1/2" pvc coupler which I cut 4 notches lengthwise to the center with the dremel's drill attachment. This is just for show.

The thicker piece of pvc is 1-1/4" pvc pipe that is friction fitted over the orange muzzle that we cored out earlier. It's about 5" long and purely ornamental. If i were to go into a nerf war, I'd probably take it off in order to open the breach quicker. I originally planned to drill holes into it line on a .50 cal US machine gun, but I kinda like it solid.
