I've been gathing information and photos on factory built Bulgarian-made Milled Kalashnikovs for quite a while. The thread above is what I've finally completed. Hopefully some of you find it useful. I'm no expert, nor do I have any notable credentials, so if you notice an error somewhere, please feel free to mention it. And feel free to post any additional info and/or photos that you might have. As new variants become available, I will try to update the thread.
Cheers to the Big Guy for designing a fine assault rifle, and Cheers to Bulgaria's Factory 10 for making such fine variations of it.
