The "Critical Mausolon". Efficient, brutal and OH so satisfying to fire. With this 3-forma setup, you can swap out the elemental status mods in the first 2 slots at your leisure. Use the right combo status for the job, and you'll never want for anything.
With 300 rechargeable rounds, [Automatic Trigger], [Critical Focus] and [Sabot Rounds] allow you to crit harder, shoot faster and fire THROUGH multiple enemies at once. With a little more than enough mod capacity at 4/60, you can replace Rubedo-Lined Barrel with [Primed Rubedo-Lined Barrel] to further increase your stopping power.
The status mods are purely to cause more pain, depending on what you're fighting. Radiation, Gas, Viral, Corrosion, Magnetic and Blast all have their place, but you choose what you need for the mission. This way, you've got precisely what the doctor ordered.
And finally, [Parallax Scope] and [Hollowed Bullets] provide more stopping power with additional Crit chance and Crit damage, turning the [Mausolon] into a powerful heavy weapon.
Critical [Mausolon]. Because things just need to die faster.
