My Energon Shockblast won't plug his missile inside his giant gun arm. It keeps falling out instead of staying in. Is the spring inside broken and how do i fix it?
Sounds like the trigger catch is warped or broken. You'll have to open it up an see if there is a little "hook" on the trigger to hold in the missle.
Replying to this thread as it's a top result in google search. I had the same problem, the missile stopped locking inside the launcher. I tried to fix the arm, but I got stuck - the black cone at the end of the green block seems glued or completely stuck. Without being able to remove it, I couldn't complete the repair and I got left with a one-armed cyclops. I recommend not bothering if the missile does not lock.
