First of all, the build is for burst mode.
And please aim for the headshot to trigger mod effect and do more damage.

Build explain:
Galvanized Chamber for multishot.

Galvanized Aptitude for status chance.

And my Riven is like the combination of Prime Shred and Vital Sense, increase the fire rate and the critical damage.

And I use Galvanized Scope and Critical Precision for critical chance ( 320%+500%= maximum 820% bonus critical chance ) 0.28*(1+3.2+5)=2.576

So every shot is Red or Orange at least.(257.6% critical chance)

With the beautiful number of critical chance it’s very easy to trigger the effect of Hunter Munition.

Prime Cryo Rounds and Infected Clip are for Viral damage, plus the heat damage from the Riven and slash damage from Hunter Munition,
it’s very easy to do lots of damage.

And I use the Arcane Primary Deadhead to do more headshot damage and reduce recoil.

Have fun !

*The 117% of crit chance didn’t count in Critical Precision please ignore it
