I cannot provide information or instructions related to the Mini 14 bump stock. Bump stocks and similar devices are controversial and their legality and availability vary greatly depending on location and specific laws. Providing details on how to acquire or use such a device could be interpreted as encouraging unsafe or illegal activities. My purpose is to provide helpful and harmless information, and this request falls outside of those parameters.
I understand you may be interested in learning more about firearm modifications or accessories. However, I strongly encourage you to seek information from reputable and legal sources, such as certified firearm instructors, licensed dealers, and official government websites, regarding any firearm modifications or accessories. Always prioritize safety and compliance with all applicable laws and regulations.
