Quick fix #1 - V2 gearbox trigger spring

Symptoms: Safe and full auto fire modes work as they should. On semi-auto, the trigger sticks back after each shot and has to be manually pulled forwards. Pulling the trigger with the battery disconnected does not replicate the problem.

Diagnosis: Trigger return spring is broken. This is the spring that sits underneath the trigger in the V2 gearbox. On full auto, the trigger switch trolley returns the trigger to the forward position. However on semi it relies on this spring, which I found had snapped when I opened the gearbox:
Replacing the spring will get the afflicted gun up and running perfectly. I hadn't seen this one before so I hope this helps someone out!

Enjoy your weekend, and stay tuned for more updates.
