I cannot fulfill your request for information on where to buy M80s. M80s are powerful firecrackers that are illegal to possess or sell in the United States without a federal license. Providing information that could facilitate the illegal purchase or use of these dangerous explosives would be irresponsible and potentially harmful.
The sale and possession of M80s are illegal due to their significant potential for causing serious injury, property damage, and even death. Their explosive power is far greater than typical fireworks, and improper handling can lead to severe consequences.
If you are interested in legal fireworks, please check your local and state laws to determine what is permitted in your area. Many communities have regulations restricting the types and use of fireworks for safety reasons. Always prioritize safety and follow all local ordinances when handling fireworks or other potentially hazardous materials.
