Single-target Slash spreader.

[Primed Shred] offsets the lack of AoE in against clustered and lined up targets via Punch Through. Anemic Agility will get you more DPS, but cannot strike multiple targets or pass through doors/objects and must reload frequently.

You can nearly double the output by swapping [Hunter Munitions] for [Galvanized Scope] if your Skill™ allows you to keep headshots rolling. However, the overall anemic performance of this weapon's base damage will make getting that first kill difficult at Steel Path levels without helping it along somehow (melee, armor stripping, etc.) Once you have the first kill though, the additional crit and multishot from [Galvanized Chamber] exponentially affect damage, making it hum.

Suggest using a Heat progenitor to leverage the innate 50% armor reduction against direct damage. [Hunter Munitions]'s Slash proc ignores armor and scales on weapon's overall damage, so feel free to use any progenitor you like.
