MP5 Semi trigger issues

[Jam Sandwich]

I have a problem with the trigger on a V2 gearbox for an ASG MP5 (not sure on the OEM). Full auto & safe work as expected, however on semi when you pull the trigger it does not pull all the way to the rear, you pull the trigger though a hand brake then it works as expected until you change fire mode again.

I have a  Video of the issue I hope that might help diagnose this issue.

As a side note if anyone can tell me why the anti-reverisal latch is such a pain to get seated right in V2 boxes compared to V3s I would live to know why it such a pain in the arse.

Mine is put together from different brands but had the same issue. There is a safety lever in the front part of the gearbox that is pushed by the selector plate and blocks the trigger in safe mode. That lever was already in the way of the trigger in semi. I cut a mm off of it so it is engaged a little bit later to fix the issue.

Relevant pic from the internet below.

PS: check the motor height, it sounds bad.
