Was hoping I got good enough layer adhesion here, and I may have, but cracks formed at the pin holes.
Fortunately did not have this happen while firing. I noticed the cracks when inspecting the gun at my desk, flexed it, and it completely snapped.
Figured I would share as an example to others. Filament choice is super important in 3D2A. Be careful.

Im aware of the viable options. Ive seen success stories with Asa. Wasn't equipped for nylon yet so asa was the next best thing in my mind for heat resistance.

Do what you want but personally I wouldn't fire one by hand. Tape it to a tree and pull a string
