Straight outta red dawn [Shedu], just changed mods around a little bit for extra damage. Vigilate Armaments' multishot ekes out slightly more damage, especially with vigilante set procs. Damage output is actually slightly higher than listed if you run [Vigilante Pursuit] on your frame (i always do) and you can push that further by slotting vigilante munitions on the exilus slot, even if it's otherwise useless.

Cautious shot is also available, if that's your cup of tea. terminal velocity slots without a forma - you'll have to give it up to Naramon the exilus. I'm going for it, myself.
