Good overview, nice to see people actually doing their research. Balanced recoil system is a simple, yet amazing concept, and recently I tried to document the history of civilian Saiga 107 - mostly what I saw myself in the last few years: https://www.thefirearmblog.com/blog/2018/06/11/balanced-recoil-sporting-rifles-a-brief-history-sr-1-saiga-107-ak15/

Very interesting thread. Usually, you don't expect to see this amount of knoweledge on an English language forum. I recently wrote an article about the development history of AM-17, thought you might find it interesting: https://www.thefirearmblog.com/blog/2018/06/29/from-dragunov-ma-to-am-17-how-rejected-designs-become-future-weapons/
