Notes before I begin:
-This thing is expensive. The parts cost me over $20. It was a bit of a suprise at the checkout.
-I had no idea I would decide to do a write-up for this at the time of the build, so the collection of pictures
from the constructing process are rather incomplete.
-Getting the parts was rather on the fly, so exact part descriptions is hard to recall.
-I really don't find it necessary to do a step-by-step tutorial for this, being as I doubt anyone will actually end
up building one. It is really just for educational purposes.
Materials:
-Abs cap (4" I believe?)
-Abs funnel thing (for lack of proper term)
-A small section of Abs pipe (connects the cap and funnel)
-1/2" Hex bushing (fits in funnel thing)
-1/2" nipple (skrews into bushing, connecting it to the bushing on my gun)
-Four 1/2" couplers and pipes (7" length)
How I did it:
I drilled four holes in the cap for the couplers and barrels, glued everything in place, and then connected it to the glued bushing, funnel, and nipple via some ABS pipe and glue. I also cut off half of the nipple where the threaded part ends because it was unnecessary. Then I painted.
Finished

This is what it looked like before I drilled the four holes in the cap and glued it together. You can see the purple primer on the bushing and the ABS pipe in the cap

Finished. With single barrel attachments and Big Blast.

Doing these three things that I didn't do will increase range dramatically:
1. Place petg in the PVC.
2. Run the petg all the way to the back of the coupler attachment.
3. Fill the dead space with the spray foam expanding insulation stuff.
This thing is heavier and more expensive than the actual gun. But nonetheless it looks awesome imo, and the ranges are way better than expected. I will post approximate ranges at some point.
