Dummy cartridge for nerf mags.

thingiverse

This is a dummy cartridge that will fit into a nerf magazine, but not be able to load or be shot from any nerf gun. This is intended as only a cosmetic prop for cosplay, photograpy or similar. Because of this it is sized in such a way that it will bind up in a flywheel nerf gun, and jam in a springer. You will likely need to print several, or use a spacer, to make sure there is enough spring tension to keep the top round in the mag. Nerf mags are designed for foam darts so they don't have high spring tension or they would crush the darts. You could also glue the cartridges in place if you don't intend to use the magazine for shooting nerf darts again. Also included is a separate version as just a casing. DO NOT try to shoot it anyway, it's not safe and you're just likely to break the gun. If you use this for prop photograpy I'd love to see, so post pictures as an "I made this" or a link in a comment.
