Hey guys , new to the AK world. I'm building my first izmash saiga and I want to use the Zenit rail system. I've done some reading on this system and it seems to be the way to go. The only part that worries me is the minor fitting. Does anyone have experience with this rail system and installing it on a saiga and how much "minor fitting" is necessary. Any help is greatly appreciated. I have converted over from the AR world and have gone the AK route. Please help with this journey, I need all the guidance I can get
