Hello. This is my [Akbronco Prime] Des and Troy. This Build includes a riven. I own 2 rivens for these guns because I love them. The one you see and another that is crit based. But this one edges out slightly.
With this riven or a similar one you are looking at 1.7 million burst dps with a sustained dps of 596k. It is a shotgun so headshots are not a problem with deadhead.
Remember to swap out your faction mods. If you dont have a riven go for fire rate or more damage. Crit wont help you much here.
Thank you
