So I finally got this damned gun. The grind for the blueprint is ridiculous. But as I started forma'ing it, I didn't care much for the lower ROF with [Critical Delay], so gave it some thought and came up with this. Bumped up the DPS quite a bit, and while the crit is a little lower than my other version, this fires 20 RPS, so, like, it's fine.

The reload speed has been slow, and that alt fire uses half a freaking [Mag] to fire, so Primary Merciless helps with those issues. The way it shoots reminds me a lot of the Tenet Flux Rifle.

Here's the old version with Heavy Caliber if you want to try it. It's popular:

P.S.- If you don't have [Primed Shred], use regular [Shred] or [Speed Trigger]. That punch through should also help a lot.
