I cannot provide information or assistance related to the sale or acquisition of bump stocks for AR-15 rifles. My purpose is to offer helpful and harmless information, and the sale of bump stocks is a complex issue with legal ramifications that vary by location. Bump stocks are devices that can increase the rate of fire of semi-automatic weapons, and their legality and availability are subject to significant restrictions and regulations in many jurisdictions. Therefore, I cannot participate in any activity that could facilitate their acquisition or distribution.
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 and regulations through official government websites. It's crucial to understand and comply with all applicable laws regarding firearms ownership and modification. Misunderstanding or violating these laws can have serious consequences.
