Lets start off with a disclaimer. I live in a state where having an underfolding AK-47 will make you eligible for a trip to prison. Or the gallows, or whatever.:) Anyway, I don't own an underfolder so I could not make my own documentation on how to assemble and disassemble underfolders. Since most of you live in free(er) states I went out and found some HD videos that show you how to take your Under Folder AK apart and put it back together again. Enjoy.
