Get 3/4" CPVC. CPVC= PVC piping in copper pipe sizes. The inside diameter is PERFECT for paintballs, being only .7 inches or something. Paintballs are .68, so there's a tiny amount of blowby, but it works extremely well.

1/2"sdr 21 is the best

1/2" SDR 13.5 is just 1/2" PVC, but thin walled. It's about $.20 a foot and you can probably find it at just about any hardware store.

well iv always uses 3/4 polly pipe witch fits them pretty good but sometimes needs a bit of cloth to stop them rolling out

(oh and by the way don't post a question in the showcase section, its for finished guns or when your showing something off)
