Welcome! I'm also new to the forum, but not to blowguns. There are several American blowgun companies you might wanna check out Venom, Berserker, and Black Rhino to name a few. PVC is good for anything less than about 3' before it begins to sag, have you seen EMT conduit? It's pretty light and won't sag like PVC, you just have to make sure to get a straight piece. What caliber are you thinking?
