Please excuse the poor pun. One of the rifles in the new Ghost in the Shell movie is based on the Tavor. Here is a display model Tavor SAR by IWI. As you can see it is completely transparent aside from the obvious parts that are not. I believe these were made to illustrate the function of the rifle but I have heard that they do not fire. I wonder if the shell would hold up to having real internals installed and fired? Probably not otherwise it would have been done by now. Still looks cool.
