Speaking just for educational purposes only, it is NOT hard at all to actually convert a semi-auto to full-auto. There are countless books out there that show you how it's done. But for God's sakes DON'T DO IT!!! Unless you are a class II manufacturer, you will land yourself in jail for 10+ years. Definatly not worth it. Learn to bump fire instead.
