This steel trigger link and 4 aluminium spacers are made by precision CNC process. The light spring is made by piano wire.
This set is used to correct the efficiency and heavy triggering force of the original trigger system.
It includes a trigger link main body, 4 spacers with difference length, 4 screws (2 screws are installing spacer to the trigger link body. 2 screws are spare parts) and a trigger link spring.
When installing a spacer to the trigger link:
1) +0 spacer means the total trigger link length is same as the original length.
2) +0.5 spacer means the trigger link length is 0.5mm longer than the original length.
3) +1.0 spacer means the trigger link length is 1mm longer than the original length.
4) +1.5 spacer means the trigger link length is 1.5mm longer than the original length.
You can choose a spacer that is best fit your GBB. Then, you should be able to pull the trigger smoothly with light force.
Remark: if the Single firing mode has full-auto shooting, this means the length of trigger link is longer than necessary. Then, please use a shorter spacer for proper Single firing.
