So, without further personal discussion, I give you....this.

This blaster was inspired by a Berzerker lying on my couch, half open. I realized I had a failed airgun Furyfire in my closet, and decided to find it. At first, I thought of using a brass breach, but my stefans don't fit brass very well, even for airguns. I decided to make a CPVC breach.
Materials
- 12" of 1/2" CPVC
- 12" of 1/2" PVC
- 1/2" PVC Coupler
- Furyfire shell
- Berzerker
- 1/4" Wood dowel rod
- Zip ties (If you don't have the screws)
- Dremel
- Cutting bit of choice (I like the diamond wheel)
- Wire snips
- Super glue
- Epoxy
- Belt sander


As you can see, I have cut about an inch of PVC stub from the original 12" pipe.
Next, glue your coupler to your Berzerker tank.

You don't really need to worry about dead space with such a massive air tank.
Next, sand the outside of your CPVC until it fits into the PVC sheath


Make sure the breach opens and closes fluently, and has enough room for your type of darts.
Get ready to do some shell cutting!
Start off with this piece, and cut a rectangle about an inch and a quarter long across the top near the end of the rail.


Cut a smaller rectangle a quarter inch back from that big one.

This next part is hard to explain, so just try to replicate what I did.

Make sure your cuts are even on both sides, and sand them down to be as smooth as possible.
Slip the internals into the shell and cut out anything that hinders your tank. Make sure the white lever on the pin fits into the small rectangle.

Next for the trigger. There is a steel rod for the old Berzerker trigger. Take about an inch of the hook side and epoxy it onto the left side of the trigger.


Close the shell and test the internals.

Now to finish the breach.
Glue the PVC stub on the end of the CPVC and let it dry.

Test the breach.

Slip it into the coupler.

Cut a 3/8" slot into the side of the plastic barrel.

Cut down the wood to an inch, and line it up with the slot. Glue that sucker in.

Cut the wood way down, to about 3/16" tall.

Glue it all up and let it dry.

Put zip ties in places around the shell to hold it all together. I have yet to purchase new screws.
Here it is with my couplered pistol.

Comments and questions appreciated.
