My SPR fires on auto without my finger pulling the trigger. If I move the selector anywhere other than safe, it begins to fire. My guess is the trigger contacts are somehow causing this.

Does anyone have advice or maybe you have experienced a similar situation?

Hello, Bacon_Stealth. This is typically seen under either of these conditions:
  • Trigger shuttle return spring has broken, leaving the trigger switch in the closed (firing) position.
  • MOSFET has failed.
When a MOSFET fails, the gate (switch) will fail in one of two positions:
  • Gate is open and the AEG will not fire.
  • Gate is closed and the AEG will continuously fire.

Any specifications given in my posts (unless specifically noted) are US market specifications. Your specifications may differ due to different markets, your country's regulations, etc.
