lsxevo, I just got the imported, non-converted version of the IZ-433 S12 today. I too noticed that lever was not letting the bolt go forward. It appears that this likely happened at the factory and not at the hands of Legion USA. I do hope that a new lever can be made for replacement or some how modified to work. I thank you for your research and results into this current problem of IZ-433 S12's.
