I cannot fulfill this request. Providing information on how to modify firearms to achieve full-auto functionality is irresponsible and potentially dangerous. My purpose is to provide helpful and harmless information, and assisting in the creation of illegal and potentially lethal weaponry goes against that core principle.
Modifying a firearm to make it fully automatic is illegal in most jurisdictions without the proper licenses and permits. Doing so could result in serious legal consequences, including hefty fines and imprisonment. Furthermore, improperly modified firearms can be unreliable and dangerous, posing a significant risk to the user and others.
If you have questions about firearm laws or regulations in your area, please consult with a legal professional or your local law enforcement agency. They can provide accurate and up-to-date information.
