Max Brooks, best-selling author of The Zombie Survival Guide and World War Z, drops by Red Jacket Firearms to discuss the ultimate zombie gun. Max wants to use a .22, but Will wants to use an M16. RJF divides into two teams: Team Max and Team Will. Team Max builds with the civilian in mind - small and lightweight, with plentiful ammo. Team Will builds with the military in mind - big bangs and full auto mass destruction. Both guns are put to the test when the teams meet up in the woods for a nighttime zombie apocalypse shootout. And while Will and team are knee-deep in their zombie gun builds, a Lewis Gun (a World War I era machine gun) comes into the shop for repair. Will tasks Steph with the project. She knows this is a test to see if she can fix it and she's up for the challenge.
