10. Grenade launcher

A grenade launcher is a weapon that you may expect to find in open war, but owning one is really allowed in the U.S. under national regulation — albeit with limitations. Classified by the National Firearms Act as a destructive device, the grenade launcher is lawful in several areas, provided that owners have properly registered the weapon and passed on the essential background checks. Nevertheless, those considering procuring and utilizing a single might not be permitted to shoot anything more volatile than flares. Back in 2005, when Seattle police were tipped off about a rocket launcher found in a vehicle, they immediately called the bomb squad after which confiscated the weapon — even though they later affirmed it had been unloaded and so legal to own.

So, these were some of the weapons that you can own legally in the United States of America. I hope you found the list interesting.
