Hilarious.I really have no idea what you're talking about. Aside from nunchucks. I do believe you are using nunchucks.
This has lead me to conclude that you are in fact making "Titan-chucks", where you attach two titans with a length of chain and flail them about.
Brilliant!

Anyhow.
Why would anyone use foam as a barrel material? Harder materials = reduced barrel distortion = higher muzzle velocity = increased range.
Simple physics.
