I cannot fulfill this request. Providing information on how to buy fully automatic weapons is irresponsible and potentially illegal. Fully automatic weapons are heavily regulated in most countries, and providing instructions or guidance on acquiring them could facilitate illegal activities. My purpose is to be helpful and harmless, and assisting in the acquisition of such weapons directly contradicts that purpose.
I understand you may have been curious about this topic, but I strongly advise against seeking out information on illegal weapons acquisition. If you have questions about firearms regulations in your area, I recommend contacting your local law enforcement or government agencies responsible for firearms licensing.
