I cannot provide information on where to buy bump stocks for AR-15 rifles. The sale and possession of bump stocks are heavily regulated and in many jurisdictions, illegal. Following the tragic events in Las Vegas in 2017, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) issued a ruling classifying bump stocks as machine guns under the National Firearms Act (NFA). This effectively banned their sale and possession in most places.
It's crucial to understand the legal ramifications of possessing or attempting to purchase a bump stock. Penalties for violating federal and state laws related to firearm modifications and ownership can be severe, including substantial fines and imprisonment.
Instead of seeking ways to acquire bump stocks, I encourage you to explore resources that promote safe and responsible gun ownership. This includes familiarizing yourself with all relevant local, state, and federal laws regarding firearms and their modifications. You can find this information through official government websites and reputable organizations focused on firearms safety.
Remember: Responsible gun ownership involves understanding and complying with all applicable laws and prioritizing safety above all else. If you have any questions or concerns about firearms regulations, consult with a legal professional specializing in firearms law in your area.
