Disclamer: This is based of the 3 configs done by THeMooN85 which I'll list here:

Everyday Use | Config A
Eidolons Hunt | Config B
Isolation Vaults | Config C

The difference with mine is a mod swap to reduce the forma cost by 1 without changing his choice of mods.

Eidolons [Hunt] | Config B

This is as I have the build set up.

Isolation Vaults | Config C

Simply remove Sabot Rounds, move Parallax Scope into the - polarized slot and add a [Venomous Clip] into the vacant slot.

Everyday Use | Config A

Using from how Config C is set up, swap the [Electrified Barrel] for a [Polar Magazine].
