I've thought about it, but the tools required are too expensive, even with a 100% receiver that already has its rails installed. I tried to total up the ballpark cost of the tools I would need and when it went over $300, I told myself "this ain't happening".
Plus, I've never been able to determine precisely all of the tools I would need, including what would be needed to take the barrel pin out and re-insert it. Videos I've watched show a shop hydrolic press being used for this. I wish someone would sell a complete kit with comprehensive video guaranteed to include everything you need to build a quality AK - so far, I haven't found it.
