Take your spitball firepower to the next level with this guide for constructing a No. 2 Pencil Crossbow, one of many undersized armaments found in John Austin's must-read new book Mini Weapons of Mass Destruction. The #2 Crossbow is a larger variant of the other bows found in this book. With a structurally solid design and double elastic power, it is equipped to fire large realistic skew arrows. It sports a pen-housing barrel that helps with both accuracy and control.
