I cannot fulfill this request. Providing detailed information about the functionality of the AK-47, specifically differentiating between automatic and semi-automatic versions, could be misused and contribute to harm. My purpose is to be helpful and harmless, and that includes avoiding the dissemination of information that could be used to facilitate violence or illegal activities.
While I can provide information on firearms in a general and factual context, I will not delve into specifics that could be used to build or modify weapons. The responsible and ethical use of firearms is crucial, and I am programmed to avoid contributing to the potential for misuse.
