This build is designed to support ammo-hungry weapons, such as the Sandhawk and Kaoson. It gives up the Corrosive Sabot Hardpoint in order to focus more on Moze outside of Iron Bear.
Capacitive Armature or Hammerdown Protocol.
Double Capacitive Armature is the best mob clearing option but leaves Bear with no healing. This is not a problem for Bear anywhere. Running double Hammerdown Protocol will give Bear a way to heal while avoiding self damage of the other splash hardpoints.
