Time to lay out all the trigger groups you have, extra parts and uppersNo I merely replace the plastic outer housing with a new one I bought.
This housing allows the selector to move past the regular semi setting. This isn't a problem with my other trigger packs, but this one seems to work differently.
Its not working like a full auto trigger pack where the hammer is released at the correct time.
Most firearms, when there is a chance when someone could make the gun do this on purpose, the bolt group is designed where a jam will occur thus stopping an out of battery condition.

Compare everything , find the differences , swap uppers and trigger groups to see if the problem follow the suspect trigger group.
Basically you have to do some tryagnostics and actual see whats working and whats not.
What manufacture for the suspect housing?
