First off, here are the materials you will need:
PETG: about 6 inches of it
1/2" brass: 3/4 inch length
1/2" CPVC: About 3/4 inch length
1/2" PVC: about an one and a quarter inches
5/8" brass (with a slot cut into it): The slot is 1 and 3/4 inches long, and is cut about 13/16 inches from the end. The whole length is about 5 and 3/4 inches.
First, dremmel out the CPVC so that the 1/2" brass fits snuggly about 1/4" inside of it.
Next, Put a seal of teflon tape around the 1/2" brass.
Then, push the CPVC into the PVC all the way to the end of the PVC.
Then, push the 5/8" brass into the PVC so that it goes into the same end as the 1/2" brass is sticking out of.
Last, push the PETG in the breach, and it's ready for use. Use it for whatever you can think of, or maybe put a magazine/clip on it.
The breach works by having the PETG seal against the 1/2" brass in the back. The 5/8" brass is to hold the dart in place as the PETG bolt(?) is moved into place.
