The bolts fired from the Auger-FS are larger and cause more damage, and the shield lasts longer. The shield will completely encircle the user in a red protective sphere in contrast to other versions. The shield is also similar to the Backlash Grenade, since all incoming attacks are deflected back into the enemy that fired the shots. Over time the Auger gets energy to generate another shield, so finding ammunition for the shield is no longer an issue.
