Reference polymer mags and other things needing prototyping: The field of stereolithography has moved forward a lot since I was first exposed to it 15-20 years ago. Parts can be built to effectively the dimensional tolerances I believe are needed for magazine prototyping for $-100-$200 each. Even less if someone has a machine and is willing to contribute labor and overhead.
