G36/UMP pin

thingiverse

I misplaced a pin for my UMP, prompting me to purchase a new one immediately. However, online searches yielded a pricey option at $7, which I deemed a total rip-off. In response, I took matters into my own hands and designed a custom pin that works flawlessly on both the G36 and UMP. Two versions of this design exist - one flush with the surface and another that protrudes 4mm outside for easier extraction.
