- Made from wood stacks and a hacked (and upgraded) autolathe as well as cable coil.
- Essentially a double barreled shotgun with a single barrel(only shoots one shell at a time).

- VIVA!

This requires additional testing but while I do said testing I'd like to make tweaks based on feedback on the code and construction process. A lot of this is pretty modular as well.
Are you asking or are you going to tell me if there is
