An actual use case for [Argon Scope] :) Since you can land headshots to get the Crit chance boost but not actually kill with headshots to get [Galvanized Scope] stacks it means [Argon Scope] is just better.

If you have firerate buffs you can replace [Vile Acceleration] with [Primed Firestorm] or [Bladed Rounds]. Also if you're a Bane mod hater then there's your replacements.

If you don't have Longbow Sharpshot then the next best thing is Primary [Frostbite], and replace [Vital Sense] (or [Bladed Rounds] if you included it) with [Serration].
