No bullets? No problem. Your buddies might joke, now, about you going all primitive with a bow, but when the Zombie Apocalypse comes...you'll be ahead of the pack. You got a bow! You need some food? Problem solved! Go hunting! Is that a "walker"? No, that WAS a "walker"! Problem solved. Also, while everyone is venturing into danger looking for bullets, you can fashion your own arrows with relative ease. [see knife and axe pins]. With a bow, you'll be a Zombie Apocalypse rockstar!!!
What is this devilish contraption?? The technology is that of a crossbow; with its many gears but it is manually pulled back like a recurve bow. Absolutely genious! http://www.leonardoda-vinci.org/Giant-Crossbow-large.html
