I have sawed the barrels down to about 5/16 in under the line, but cpvc and my petg does not fit into the barrel stubs. What barrel material could I use.

Your problem may very well be that you did not saw quiet far enough back to catch all the tight fitting stuff. What I would try doing is taking a screw drive, or a pair of needle nose plyers and pry the small ring from the inside of the barrel stumps, after this is done 9/16ths should fit very nicely.

Or you can Just dremmel around the inside edges of all the barrel stubs, then your barrel material should work.

If you have a dremel, then go with Bag's advice...that will make anything fit, and it won't cost you any more.

I also went around 5/16" under the line, and my 9/16" brass fit in just fine, but that will cost you more money (~$6 for two feet of brass at my local Ace Hardware), and you should be able to get PETG to work.

My PETG is alittle thicker than cpvc. Could I get cpvc in there after thinning the barrels?

Also, I don't have a dremel and aren't dremels really expensive?

Use a file or sandpaper. I use both.

I forget what a file is. I'll try sandpaper but im trying to get as little barrel stuff and sandpaper in the gun as possible.

Because I have a spare At3k turret lying around, I used a Dremel to sand down one barrel and put in a piece of 1/2" CPVC. While I was able to do it, I wouldn't recommend it because (1) If you're doing a barrel support mod like Cxwq's, your barrel support will have to be sanded down until it is very, very thin, and (2) Without a Dremel, you will have to suffer a lot of pain to get all six barrels in there. Trying to get anything thicker than 1/2" CPVC will be next to impossible, in my opinion.

Yes, the Dremel moto tools I see at Home Depot are usually selling for 60+ dollars.

Here's a picture of a file.

I wouldn't worry too much about getting the "barrel stuff and sandpaper" inside the gun, because the gun can get cleaned out...just make sure you avoid getting any in the air tank.

Alright thanks, I think I am getting PETG with thinner OD.
DO you think 7/16 ID would be too small or still usable for good distances on the at3k.

I think that that depends on the particular Foam Backer Rod that you're using to make darts (assuming that you're using micro stefans)...7/16" ID wouldn't fit my 1/2" FBR very well, and if it fits yours, I'm guessing it'll be a little on the tight side.

Where are you getting your PETG (I'm just curious, never used PETG myself)?
