The Golden State Second Amendment Council would never recommend doing this in California. However, if you are in a firearms-friendly state that allows making your own AK-47 from a garden shovel, this is a great tutorial.
Boris ‘Son of Kalashnikov’ has a step-by-step DIY tutorial on how he built an AK-47 from a shovel! Surprisingly, the receiver is much stronger than any commercially produced AK-47.
Unfortunately, Boris’ posted pictures are a bit on the small side. Fortunately, Left Coast Firearms has posted a gallery of full-size pictures for your viewing pleasure.
Just remember people: don’t attempt this at your California home!
