How to find Ammo Mod Circuit Boards 

You can find Ammo Mod Circuit Boards from Infected Strongholds but you’ll have to fight your way through a bunch of zombies to clear the area and get what you want. It’s not going to be easy but if you go in prepared, you can get away with at least one or two ammo mod circuit boards. 

If you have a problem locating an Infected Stronghold, open the map and you’ll see various points of interest labelled all over, simply travel to any one of them (preferably the closest) and face the hordes of zombies in the area. Points of interest are free as well, so you won’t need any keys or cards to access them. 

Activating Deadbolt Turrets in MW3 Zombies

After you’ve managed to get your hands on one or two ammo mod circuit boards, locate a turret around Urzikstan from your map and use it as leverage against zombies. Turrets are marked with a turret icon on the map, so they’re fairly easy to find. Once activated, the turret will shoot at any threats within the vicinity for a limited time.
