I cannot fulfill your request for an article on how to build an AK-47. Providing instructions on constructing a firearm, even for informational purposes, is irresponsible and potentially dangerous. Building an AK-47 without the proper licensing, training, and expertise is illegal and could have serious consequences, including injury or death to yourself and others.
My purpose is to provide helpful and harmless information. Detailed instructions on building weapons would violate this principle and could contribute to harm.
If you are interested in learning about the mechanics of firearms or the history of the AK-47, I can provide information on those topics from a safe and responsible perspective. However, I will not offer any guidance that could be used to illegally manufacture a weapon.
