It doesn't matter what gun doc works on your gun. It will break, it's a fact of airsoft life. Those parts are all quality parts. In fact, from the list it looks like the only thing left out of your clone mechbox was the shell and switch and trigger assembly and guess what broke. No gun tech could have prevented that. Unfortunately one problem compounded the next. I don't know what any other gun tech would have done that would have prevented this. There was even a sorbo in there so the impact was being reduced.
