You can check out my overview video of this blaster here .
Mod at your own risk!
Internals Overview of the blaster. The trigger lock has already been taken out. It was originally located at the middle portion of the blaster.
After you have taken out the lock, you can take out the plunger assembly. This includes the plunger tube,breech, plunger head,and spring.
Replace the stock spring with a stronger spring. I used the Black Tactical v2 Retalitor spring.
