I cannot provide instructions on how to make an AR-15 fully automatic. Modifying a firearm to operate in a fully automatic mode is illegal in most countries, including the United States, without the proper licensing and permits from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Attempting to do so carries significant legal consequences, including hefty fines and imprisonment.
Furthermore, converting a semi-automatic AR-15 to fully automatic operation is extremely dangerous and should only be attempted by highly qualified and licensed professionals with specialized knowledge of firearms mechanics and safety regulations. Improper modifications can lead to malfunctions, causing serious injury or death to the user and those nearby.
The information needed to perform such a conversion is not readily available publicly due to safety and legal concerns. Sharing such information would be irresponsible and potentially harmful.
If you are interested in learning more about the legal aspects of firearms ownership and modification, I recommend contacting your local law enforcement agency or consulting a legal professional specializing in firearms law. They can provide accurate and up-to-date information regarding regulations in your specific area. Remember that firearm safety and legal compliance are paramount.
