Been screwing around with some of my parts kits lately since I have a couple AK recievers now debating on what I want to build. I'd like to do a Polish Beryl clone, Anyone have experience using their rail setup? If so who did you get it from? Haven't found vendors in US selling it yet although a couple are working on them, I can order one from europe though, I want to make sure its worth it first though, also need to find a source for there sight setup when equipped with the rail. Pic for reference.
