CPVC Breech
CPVC Breech Write-Up
Purpose:Instead of having to take off a barrel, find a dart, shove it in the back, push the barrel back into the gun's coupler, and finally align it, I have composed a simple breech that reduces the steps to pulling the barrel forward, dropping a dart in, and finally pulling the barrel back into the coupler.
Materials:
-3" of either [1/2" PVC], [1/2" 315 psi PVC], or [AT2K pump tube] ( I did the write-up with 1/2" PVC. If you chose either the 315 psi or pump tube, you do not need to dremel it and can skip that step)
- 1/2" CPVC coupler
-Dremel
-Hot glue gun w/ 1 stick of hot glue
-Sharpie
-Vice(not needed, but recommended)
Procedure:
The PVC and coupler.
Take the PVC, and squeeze it in a vice, so that it forms a slight ellipsoid shape. Using your dremel bit, sand as far as you can get in, and then flip the PVC and do the other side. Once you are done, the PVC should be able to slide along a peice of 1/2" CPVC fairly easily, like so:
Take your sharpie, and draw a line at 2 1/4" on the PVC. Extend it almost half-way around the PVC, and then draw straight lines down to the end of the pipe. You are going to cut along these lines using the Dremel's fiberglass-reinforced cutting disc. Sand down any sharp edges.
This is what it should look like.
Now, take a long peice of CPVC, and attach a coupler to the end. Slide the PVC down until the coupler and it almost touch, and liberaly apply some hot glue. Once the hot glue is in place, push the PVC down until it touches the coupler. DONT GET HOT GLUE ON THE CPVC. This will gum up the barrel and add friction to the breech.
Allow to dry.
That's it, you're done. This is what you should end up with.
To use:
(Note: It's recommended that you put a small peice of CPVC behind the coupler, instead of attaching the coupler directly to your gun.)
Pull the barrel forward, exposing the breech. Drop a stefan in. Pull the barrel closed.
