Just read the title :P Anyways, I wanted to change the barrel on my hopper, but didn't want to dremel out a piece of 1/2 PVC and hammer the 1/2 CPVC into it. So this is what I did :D
What you have to do is get a 1/2 CPVC coupler, and dremel out one side of the coupler. Now get a hammer and pound the coupler into your hopper!
Now you have a hopper that you can easily change to different barrel lengths!
Thanks for reading,
