Using this, printing this today, do you know if this is airtight already or should I just wrap it in tape so no air escapes?

All I had to do was clean up the inside of the barrels from some of the printing imperfections; what I did was drill in REVERSE with a half inch bit down each barrel. Instead of tape, I epoxied the stub of CPVC into the end, which guaranteed a seal and was permanent.

I GOT THIS ONE
You mentioned something about 3D printing, which I've done a bit with for absolvers. I made a simple 3 shot barrel in CAD, here it is:


Just stick a stub of 0.5" CPVC into the back to attach it to a coupler system.

Also here is a link to the .STL, if it doesn't work for some reason let me know:

Hey that's me! I did pretty much exactly what shmmee said. It's in no way optimal but it gets the job done and I didn't have to mess with the tank itself much at all. Here are some pictures that might help

 


Bonus shot of the whole thing

For the first one, you should definitely leave the holes on the back of the plunger tube. These help avoid a vacuum in the rear part of the plunger as the piston moves forward, making it move faster in general. I think there is a small hole in the plunger head that you'll want to fill. This mod guide by SG Nerf covers most of the basics, just ignore the battery part, it's a bit outdated in that subject.

This is fucking awesome, everything about it. That double hopper system is so cool, I would never have thought of something like that. You can reload one while shooting the out of the other hopper, so you're pretty much never out. I need to try this.
