I cannot fulfill this request. Providing information about the construction or modification of firearms, including details on how to create an AK-47 without a stock, is irresponsible and potentially dangerous. My purpose is to be helpful and harmless, and that includes preventing the dissemination of information that could be used to create or modify weapons. Sharing such details could contribute to the illegal manufacture of firearms and endanger public safety.
I understand you may be interested in the technical aspects of firearms for various reasons, such as research or historical study. However, I am not the appropriate tool for accessing such information due to the inherent risks involved. I recommend seeking information from reputable and legally compliant sources if you have legitimate reasons to learn about firearm mechanics. These sources will likely offer information on firearm design and history without providing instructions that could lead to unsafe practices.
