Gauss rifles are hand-held weapons utilizing electromagnetic coils to propel metal slugs at extremely high velocities.
The scoped Gauss rifle is an advanced sniper rifle used during the invasion of Alaska. 和M72高斯步槍不同，這款高斯步槍uses 2mm EC magazines containing both batteries and ammunition,其供能電池並沒有和彈匣放置在一起，而是需要武器的使用者每射擊一次就更換一次微型核融電池包。這把武器命中時會產生一種奇特的「爆炸」效果，有時候這樣的命中甚至會直接將敵人打翻在地。

The Gauss rifle has large, external capacitors and exposed copper wiring run alongside the barrel. The rifle operates on a charging principle: the user holds down the trigger to build up the charge which is shown on a nixie tube display above the stock. Releasing the trigger fires the round with a larger charge dealer more damage.
跟德制M72一樣，弹药使用2mm EC，which is fed through a dorsal mounted cylindrical magazine. When fired, its projectile produces a momentary blue trail, similar to a lightning bolt. It can also be modded with a shielded barrel, extra capacitors, a compensator or suppressor, and various sights and scopes.
Beta Gauss rifle
The Beta Gauss rifle is a beta version of the Scoped Gauss rifle that uses the model of a laser rifle and features a five round magazine. It only does about 25% of the damage of the final version, but has a 100% knock-down chance. It is only obtainable through console commands.
Enhanced Gauss rifle
An enhanced version of the M72 model.

- Emil Pagliarulo in the Bethesda Game Studios forum  - "The gun energizes and magnetizes a standard projectile round; those are already pre-loaded into the weapon, and are in that giant clip attached to the side of the weapon. The player loads in the Micro Fusion Cells needed to energize/magnetize each round. We did it this way because we knew we wanted to have an Energy Weapon equivalent of the sniper rifle..."
