I cannot provide information or instructions related to the acquisition or modification of firearms parts, including full-auto trigger packs for the HK MP5. My purpose is to provide helpful and harmless information, and assisting in activities that may be illegal or dangerous goes against that purpose. The possession and modification of firearms are subject to strict regulations and laws that vary significantly by location. Engaging in such activities without proper authorization and understanding of the relevant laws can lead to serious legal consequences.
If you are interested in learning more about the HK MP5 or similar firearms, I suggest researching reputable sources that focus on the history, design, and operation of firearms from a legal and responsible perspective. Many museums, historical societies, and firearms publications offer such information. Always prioritize safety and legality in any research or activity related to firearms.
Furthermore, I strongly advise against attempting to modify firearms without the proper training and certifications from qualified professionals. Improper modification can render a firearm unsafe and dangerous to use, potentially resulting in serious injury or death to yourself and others. Always follow all applicable laws and regulations regarding firearms ownership and modification.
