Automatic-Gauss Rifle

For Fallout-verse lore; it pretty much has the same principles as the original Gauss Rifle, this one - the Automatic-Gauss Rifle (hence the name) - is fully automatic!  While using a converted car battery as the energy source instead of Micro Fusion Cells, it gets a whopping 120 rounds a minute.  Though with such speed, it has a lower alpha damage rating than the original Gauss Rifle.  No one truly knows the origins of this rifle, it could be some crazy scientist's idea, maybe it could be someone tired of switching MFCs constantly after every pull of the trigger, or it could be from the very lands of America's Pre-war enemy, China, giving them the middle finger and saying "We got better Energy Weapons!".
