This post is part 1 of the series "Best Weapon Crafts" and provides both the best initial PVE specifications and the best final PVE specification for craftable weapons.
Barrel: Initially Polygonal Rifling then Smallbore when unlocked.
Reasoning: Smallbore is a light.gg gold barrel. The only other two light.gg gold barrels are not considered as they both improve handling speed which is not relevant to me.
Magazine: Initially Appended Mag then either High-Caliber Rounds or Ricochet Rounds when unlocked.
I prefer Richochet Rounds.
Solar AOE Build
Perk 1: Initially Turnabout then Stats for All when unlocked.
Perk 2: Initially Adapative Munitions then Incandescent when unlocked.
Reasoning:Incandescent triggers Stats for All. As a solar weapon and with the perk incandescent, this weapon is supposed to be used with a solar subclass.
Non-Solar Fake-Monte-Carlo Build
Perk 1: Initially Turnabout then Dynamic Sway Reduction when unlocked.
Perk 2: Intially Adapative Munitions then Tap the Trigger when unlocked.
