Firstly, Gather your materials.
-1/2 CPVC (I have not yet tested barrel lengths, 6-8 inches would likely be sufficient)
- Your Marshmallow Popper
Next, Fill up your "Marshmallow" tube with darts of choice. I used cut down Nerf streamlines in this case.
Finally, Push CPVC barrel of choice into front. It should fit snugly; roughly as tight as CPVC in PVC, but slightly looser. It will give you an airtight barrel seal.
There you go! Now you have a high-ROF, pump action blaster with a solid factory paintjob to top it off.
Edit: Another cool little thing I just remembered about this blaster is it features a check valve.
