Some users who have modded their Nerf Stampedes may have encountered an odd issue whereby their blasters continue firing even after they release the trigger, resulting in erratic firing operation.
Here is a cause of this phenomenon:
The Stampede's Plunger Catch Control Spring has somehow popped out of position and no longer functions properly.
The solution is to remove the catch control component and reposition the spring back to its original position, then install it back into the Stampede.
An even better option is to replace the stock catch control spring with a stronger spring of the same size, then applying some tape to the gaps to prevent the spring from popping out again.
I have tested installing stronger aftermarket catch control springs into many modded Stampedes and have noticed an improvement in operational reliability and firing consistency.
This should solve the Stampede's "auto-running" and erratic firing issues!
