The mount is more of a robotic arm that extends down from the backpack bit and helps to transfer some of the weapons weight, as ell as assisting in aiming it by providing a somewhat more fixed point to rotate the weapon around. aim it. the shield is located on the gun and serves as defense when he's actively firing.
