A great single-target bosskiller weapon, best used with any CC ability for easier aiming.

[Trick Mag]: Highly optional. Only use if you really want to perfect the build. Alternative good picks would be [Hawk Eye] or [Steady Hands].

[Hornet Strike] and [Galvanized Diffusion]: Basics. Go on about every build.
[Pathogen Rounds] and [Frostbite]: For viral. The insanely high fire rate this weapon gets when you hit headshots makes up for the otherwise relatively low status chance.
[Primed Heated Charge]: For damage and the option of heat status (CC +a bit armor reduction)
[Galvanized Crosshairs]: Further boosts headshots.
[Primed Target Cracker] and [Primed Pistol Gambit]: Boost crit attributes.

Secondary Deadhead: Further boosts headshot crits. Replace with merciless if you miss a lot for less damage but more reload speed.
