Okay, after searching spudfiles and the internet for a while I cant find what size pvc I could use for .40 caliber darts/paintballs. And since the darts are still coming via the mail I cant take one to the store with me to size it..
Any input would be great. Thanks!

3/8" Sch. 80 has an inside diameter of .423" and 3/8" Sch. 40 is .493" both should work just fine.

I dont think my home depot has sch 80, but I will try the 3/8'' sch 40. Thanks man 8)

.093" gap?!
*measures out .046" on the calipers, and proceeds to bewilder family by proclaiming "It's huge" and waving the calipers in their faces*
The sch 80 is a good bet, and will be stiffer (improtant in tubing that small).
Mcmaster should carry it, and shipping shouldn't be too bad.

You must mean "SDR 13.5" which wouldn't work very well. The inside diameter of even 1/2" SDR 13.5 is .72" that would leave a .32" gap.
EDIT:
Yes, you can use sch. 80 pipe with sch. 40 fittings, but use the pressure rating of the sch. 40 fittings.

That would be for .68 caliber paintballs...
As for a .40 barrel, why not JB Weld a regular blowgun barrel to a threaded plug or cap and use it that way?
Or sleeve the blowgun barrel in SCH 80 and load up the gap, which would be very small, with JB Weld.

Well, i've scraped the whole dart thing and will just make some 1/2'' wood darts with some dowels and nails cause I dont want to ruin the blowgun I just got for my birthday yesturday lol. New sniper rifle to come..
