Hello, wanted to see if here is anyone online/expert about this technical stuff. So compatibility regarding ak47 parts for saiga12. In example ALG triggers or any other ak47 triggers for that matter, do you usually have to dremel it or something or are those pretty much a drop-in parts? Other is the dust cover, mine in saiga is 237mm long and I bought a FAB Defense pdc dustcover which is 246mm. Also bought a Vltor cmrd ak handguard and a magpul zhukov-s stock. I did apply licenses for 7.62x39 also, so if the parts wont fit at all they will be used later.
