Selling my KWC Mini UZI CO2 GBB SMG, which was intended to be a high-performance custom build. It’s had a significant amount of work and upgrades put into it, but I haven’t had the time to finish tuning it properly.

The gun does fire and has excellent compression, but it needs the right high-pressure regulator setup and final tuning to run consistently. Ideal for someone experienced with GBB systems or HPA builds.

Upgrades & Work Done:
Custom 3D printed Picatinny mounts (front grip + optics)
3D printed hop unit (Airsoft Engenuity)
Maple Leaf tightbore inner barrel
Maple Leaf hop rubber
Custom 3D printed HPA tap
MP5 300 round magazine conversion
Fully serviced and sealed by Airsoft Engenuity

Performance Notes:
Very strong compression
Fires, but currently inconsistent
Needs a regulator capable of higher pressure output to perform correctly
Would suit someone who understands GBB tuning / HPA setups
