Being 25% Stiffer than the executioner, The Zombie Slayer Crossbow Arrows are designed to optimize zombie skull penetration. Built for accuracy and penetration, these carbon Zombie Slayer Crossbow Arrows are manufactured with the tightest ± 0.001in straightness tolerances to ensure you never miss that critical head shot. This is what makes a bow or crossbow an ideal survival tool as you are able to reuse ammunition. What makes our Zombie Slayers a critical part of your arsenal is the unmatched durability. We test our shafts by shooting through 3/4in pressure treated plywood and several other materials. Your typical stinking, rotting, zombie corpse will prove over and over to be no match for our shafts.
