Ump lower
- Thread starter burtjani
- Start date
They can be found in the US and imported, I built a clone up a few years back and that is what I did. There are a few importers a z tech armoury can put them on their webstore, just remember to also pick up correct ump mags with it. The USC internals will fit in fine, there will be a hole that you wont have a pin for but you can find any pin to plug it. I personally 3d printed one to fit
