Just made this to get a gun with the highest fire rate I could. If you get a riven, go for -recoil, +fire rate, and -reload time with a curse that doesn't impact anything. You can replace Stunning Speed to fit the riven, then use Primed Pistol Ammo Mutation in the exilus. Secondary Deadhead is for the meme because no way are you getting a precision kill with this. Build would have higher damage and slightly more ammo with Twin Vipers Wraith, but this one has a higher riven dispo so for my purposes Twin Vipers is better.
