You don't want to order pipes from there, they aren't cheap...

Just to appease you, part number 8859K21 is a decent barrel. But they are sold in packs of 12.

You really should make a PVC coax first to understand the concepts. They are more forgiving for newbies. Then once you understand it better, make the mini.

I stick with minis as I dont trust larger ones such as my overpowered gatorade gun which I threw away. I like sticking to minis. I just need a forgiving mini that has decent power.

Minis are harder to make with precision, that's all I'm saying.

The plugs I was going to buy are so small they plug the barrel and dont make a tight fit in the chamber....

Well this is why you get the chamber and barrel before you make the piston.
