Ok so upon reviving an AT2K I cranked it open. During this mod you are able to do Tatum Bulls "Airflow mod" but this focus on getting the Cpvc barrels in and airtight

First get you supplies:

-Sharpie
-15/32 Brass 1 inch segments
Pipe Cutters
4 9 inch pieces of Cpvc
Epoxy
Hot glue
Plumbers goop
Dremel (Optional)
And of Course a Screw Driver

Supplies:

First start by taking your craking it open, there is a glued tab by the pump so take your saw or dremel and cut open the tab.



After taking apart your turret. Dip it into a pot of boiling hot water and then yank it out with pliers. Then I advise you do Tantum's Airflow mod as it will hep with ranges.

Linky

After doing Tantums, then take you brass like so:



And then Glue it in, epoxy, or whatever the heck you want to do to it in, but make sure that there is 1/2 inch of brass over the lip.

Then take you Cpvc and slide it ontop of the 15/32



Goop them ontop, it should create an airtight seal with minimum deadspaces.

Finish up your other barrels and screw your gun back together.

And your done, Ohh and I suggest gluing the trigger spring tank pin with hot glue as it helps with ranges aswell.

Ranges:With a 1 1/2 dart, 2 copperhead BB's 4 Plugged pumps
97
96
94
103
100
97
76 (Bad Dart)
99

Hope this make it into the directory!

Grate mod.

I like it, it's like an inside-out coupler. My only question though is why CPVC? With that long of a barrel I think you'd do better with something a bit looser like PETG or maybe 9/16" Brass.

I agree, but CPVC is very cheap and easily availible.

For those reasons alone, it works for me.

Nice mod, just the type of innovation that interests me.

[Hi Yah]

Try drilling out the cpvc with a 1/2" spade bit. It'll give the barrels an air-gun fit with most hardware store foam.

Nice mod, although, are you are about those ranges? They seem a little high for barrel replacement only. May I suggest an airflow mod, done by TantumBull here.

*edit* Sorry, didn't see that you had already done the airflow mod.

Unless OP edited his post recently, he already knows about (and did, apparently) TB's airflow modification.

@ xbox180: how good is the seal, is it really air-tight? I just hotglued the PETG barrels on all my AT2Ks, and I get ~110' approximately. I think the seal matters less on loose barrels, but if the seal is 100% perfect, then I may have to do this.

Ok well tantums mod had been done. The OP has been plugged and the tank to turret seal is great. I just etaped the little stub and it works fine. My darts are loose log home shit and work great in cpvc.
