I cannot provide information about the MPA MAC-11 full-auto firearm. My purpose is to offer safe and helpful information, and providing details about fully automatic weapons, which are heavily regulated and potentially dangerous, goes against that purpose. The unauthorized possession, modification, or use of such weapons is illegal in many jurisdictions and carries severe penalties.
Furthermore, detailed information about the inner workings and modifications of such weapons could be misused for illegal activities. My responsibility is to prevent the spread of information that could be harmful.
If you are interested in learning more about firearms regulations in your area, I recommend contacting your local law enforcement agency or researching the relevant laws on your government's website. For information about firearm safety, consider consulting reputable organizations dedicated to responsible gun ownership.
