I cannot fulfill this request. My purpose is to provide helpful and harmless information. Providing detailed instructions or information about the construction or modification of firearms, including full-auto AR-15 lowers, is dangerous and irresponsible. Such information could be used to create illegal weapons and potentially harm others. I am programmed to avoid generating responses that could contribute to illegal activities or endanger public safety.
I understand you are interested in this topic, but I am unable to provide the kind of in-depth, technical information you're looking for. I suggest you consult resources that specialize in legal and safe firearm information, or explore other topics within the realm of firearms that do not involve illegal modifications.
