Which would make sense except that the comparison breaks down in that the AR-15 is not the most ideal gun to have for an apocalypse scenario. They were built to precise tolerances, and as we found out in Vietnam, if they are not cleaned regularly and completely, they become horribly unreliable.

Also, 5.56mm bullets are really, really small. They’re more of a penetrator round.

If you’re fighting zombies, you want a bullet with more mass, as it imparts more kinetic energy into the thing you hit. Putting holes in zombies is pointless. You want something that can potentially knock one down.

Me? I’d go with a 12-gauge shotgun loaded with slugs. Good range, huge rounds, and a pump-action is less likely to jam than a semi-auto.
