The XM42 claims to be the world's first commercially available flamethrower, which means that almost anyone will be able to buy the handheld incendiary device. We have to wonder, is that really a good thing? The XM42 flamethrower is gearing up for production via the crowdfunding site IndieGogo. Honestly, it looks dangerous, but it's designed to be much safer than any homemade improvised device a teenager or doomsday-prepper would make. Even a "safe" flamethrower is still dangerous. For the XM42, safety certainly doesn't translate as weakness because the it packs a formidable, fiery punch.
