So I'm building them using really strong cardboard, and cutting them with a laser. (same way I'm making the keyblades). I'm cutting different layers and stacking them together. The SMG's stock will be able to pop out and back in, also the handle in the front swings up and down.
The BR may have some fancy things but as of right now, it doesn't. And I'm doing a complete re-haul on it anyway. I'm remodeling the handle grip and barrel grip The SMG is glued together and is really really sturdy so I'm not sure if I'm going to resin them or not.
Anyway, I'd love to hear your thoughts and ideas, so please feel free to comment
