Alot of choices here really, Where to begin...

Possible orange / Red Crit Headshot build with around 150% + crit in incarnon, if u combine this with something that grants more primary crit chance,
Like for example [Ash Prime] with [Smoke Shadow] mod it will be insane.

Incarnon mode = Hunters Mantra + Extended Volley + Commodores Fortune. This is the current chosen build.
The Incarnon Mode has 6.6x Crit multi so that will get tripled from getting red crits.
Overframe still doesnt have an incarnon calculation built in yet but I believe this should be very strong.

u can also go non headshot based with [Point Strike] > [Critical Delay] & Faction mod > Galva scope + Swap the arcane to Merciless.
then u would also Swap the Incarnon effect Commodores Fortune to Survivors Edge.

Both should be very very good - Im still testing, The rest is up to ur preference.

After some testing I found out that the Arcane Deadhead doesnt proc off Slash dots, So we are using Merciless.
