Thanks for all the replies. I'm not fussed on the missile launchers but mainly the conversion springs like STL pointed out on Cybertron Override and of course activators and plenty of the spring loaded mechanisms in a lot of the Cybertron figures with the Cyberkey functions. I guess it's not so much an issue unless they eventually rust and break.

As for the missile loss, it's amazing where they end up even if you saw the vicinity it landed. I guess the pinball effect makes them go where no toy missile has gone before.
