I did this mod because of my inability to open up the gun due to rusted in screws. Fuck Goodwill stuff.
For such a simple modification, it turned out quite well.
Anyway, I'll get on with it.
You will need:
Your choice of barrel material.
and nesting material.(PVC, etc.)
Ok, step 1.
Take the PVC
and the PETG
and nest them. This will act as the base.
I used 12" of PETG inside roughly 2 1/2 inches of Sch.80 PVC.
Put this piece aside, you wont be using it for this mod.
Now line the nested PETG up with the inner threaded stub.
I removed the AR, however, you don't have to.
Wrap duct tape around as necassary.
I then sealed it with E-Tape. It is airtight now.
I used metal duct tape to stabilize it.
It may be fugly, but it took about 10 minutes to do, and gets 160' flat.
Disclaimer: I am 6' 2", and I shot from my shoulder.
