I've been lucky enough to fire a few machine guns out of state and at a charity event in Los Angeles a few years back. They are a ton of fun, and most people walk away with a huge smile on their face after they have fired one. The question that often seems to come up is how you can legally purchase a machine gun. If you live in one of the unfriendly gun states like California, NY, or Hawaii, you can pretty much count on it being damn near impossible. If you live in one of the other states in the union with lower costs of living and a better lifestyle, you can legally own one if you got the cash. (Like always be sure to do your research and check your local laws.) Check out this long, but informative, vid on how the process works.
