The second amendment gives American citizens the right to bear arms, and we've managed to expand that definition to include a whole ton of heavy artillery. You can start building your personal armory. But what’s legal and what’s not?

If you’re thinking automatic weapons—here’s the thing: automatic weapons aren't legal anymore—well, kind of. Laws prohibit everyday citizens from owning any fully automatic rifle made after 1986. This sneaks in by the hair of your chinny chin chin. The M134 has a capacity of 166 shots per second, and packs so much recoil that you'd literally rip your arms off if you tried to hold and shoot it yourself. Mount it on a vehicle and your all set.

For those die hard (no pun intended) Walking Dead fans and lovers of the cross bow, think Daryl Dixon. Here’s the good news…you can walk around with one of these cool weapons just about anywhere you want…at the least –during archery season. Only state you’d have problems in is the state of Oregon. Crossbows made their first appearance in China during the Warring States period, crossbows combined the lethality of a traditional bow and arrow with lightness and ease of aim. They were a common weapon for assassinations in the middle ages, and some modern armies have used them for urban warfare.

Passing laws regulating flamethrowers is kind of tricky. If you make them too general, you inadvertently end up outlawing Zippo lighters. If the laws are tapered down too much, flamethrowers like the XM42 end up falling through the cracks. This flamethrower is currently raising funds on Indiegogo for a full production run, but the rock bottom price of $699 it's not a cheap buy. Are you ready for this interesting bit of news? Flamethrowers were banned by the Geneva convention for use in warfare, everyday civilians like you can have one—not soldiers.
