Multitool Mod: Railgun

Description
It's not often that it takes more energy to get the projectile up to speed than to create it in the first place, but then there are railguns. Using relatively long super-conductive rails and extremely high voltages and currents to produce massive magnetic fields, these weapons fire so fast other bullets might as well be standing still by comparision. Frequently breaking speed of mach 10, these weapons use nitrodium shot, because any other material would vaporise from the sheer energy strain.
