Element of choice is Toxin to combine with [Primed Chilling Grasp] to make efficiently Viral as combined with Radiation, [Hunter Munitions] and the forced Impact Proc you get 5 status effects procing which allow [Galvanized Savvy] to take maximum effect.

[Galvanized Acceleration] massively reduces damage falloff, increasing DPS and making the weapon much more usable for long range shots.

If you do not like Factions mods, the next best mod is [Primed Point Blank].
