Removing the head, or destroying the brain. The only sure fire way to put a zombie down for good. Yeah, yeah, zombies are slow, and don’t really understand that the rifle you’re aiming for their dome is going to end their shuffle to the buffet line, but that doesn’t mean you have the luxury of waiting for them to up close and personal. With large waves, you’ve got to hit them on your first shot, and you’ve got to do it from as far out as possible. The Trijicon ACOG® is your rifle’s new best friend. With 6x magnification, the ACOG® incorporates Trijicon’s Bindon Aiming Concept™ (BAC) – a revolutionary both-eyes-open method of aiming. It’s even got a bullet drop compensator with additional aim points for estimated trajectory of the 5.56mm round. Meaning you can pair this puppy up with your Sig556 and get maximum potential out of every round you fire during your undead crowd control shift.
