When croc-hunting, or just jusing Crocs to the shooting-range. Or maybe a gift to a friend who loves Crocs and shooting :)
Based on my other model, 3 round cartridge clip (308) by Walkonwater3D - MakerWorld, but attaches to Crocs instead.
Tested with 308win, based on experience this means that 3006, 243win etc also fits.
There is as lip that goes into the cartridge-groove, so you have to pry it in at an angle. Cartridges fit snug into the clip/holder. The holder/clip is easy to install on Croc shoes.
