I think you guys will enjoy the book a lot. There's a lot of interesting history in each of the chapters, a lot of cool prototype stuff that hasn't been seen before, and a lot of good detail about UZI parts that will help people understand surplus parts better then they've ever been able to before.
The research for the book was fun but a lot of work. Even when working with people who were directly involved in a project, they usually had biased or incomplete perspectives that couldn't be taken verbatim. I would have to correlate multiple bit of information to sort out fact from fiction. Fortunately, the more pieces you get in place, the more sense you can make out of the remaining pieces. Most people were extremely helpful, though occasionally I ran into roadblocks. For example, I had an overview of the Serbian M97 (a knockoff of the Mini UZI), but I wanted more detail. A work colleague of mine was from Serbia and was good friends with someone in their state department, who put me in touch with the Serbian Minister of Defense. Obviously he has access to any information I might want. Unfortunately he was not helpful and actually denied the existence of the M97. I assume he was worried that Israel might not like the fact that made an unlicensed copy and wanted to keep it quiet, so I had to go with the information I had. Other research was much more productive. Jonathan Mossberg gave me the inside story on UZI America, which was very interesting. There was a big political battle going on over that deal and he had all of the letters from Diane Feinstein, Bill Clinton and Benjamin Netanyahu to document the ordeal. Very interesting stuff.
