How do you have your stock attached?

Hot glue. why?

I was worried about that. Yeah, like rork said, this has zero chance of holding up to actual use. Screws will work, so long as you're behind where the plunger head sits at its furthest back point. Other physical methods like pipe clamps could also work. The main issue that you're going to be fighting is that there will be a huge amount of stress force on the attachment point, because the stock acts as a lever. It'll need to be secure, or it'll let go, probably at the worst possible moment.

I fixed that the other day.

EDIT: Guys do you think I should make the barrels 12 inch? They are 10 inch right now. I just have the feeling they NEED to be 12 inch... Or 14 inch... He he he...

If it's hitting reliably over 100ft, it can probably handle 12 inches of barrel.

She should be able to handle up to a sixteen inch barrel before running into deceleration issues. Maybe more, maybe less, depending on just how long the plunger draw is and how much air is being lost through leakage.
