[Terminal Velocity] is highly recommended for a primary fire build, due the range being rather limited already.

This build is for primary fire- if you're using alt fire (automatic), swap [Internal Bleeding] to [Hunter Munitions] (and the same for the below variations)

For corpus, swap [Internal Bleeding] for [Stormbringer]

For infested, swap the viral mods and [Internal Bleeding] for [Stormbringer] + [Infected Clip] + [Bladed Rounds]

If you want to save a forma you can use crit delay over point strike

If using external primer (companion) or nourish- (suggested to do this)
Drop both viral mods for rifle elementalist and bladed rounds/[Serration]
