Weapon for Gyre build - https://overframe.gg/build/889913/

In this case, the rifle has one job. Shoot through a ball of enemies, punch through and trigger a lot of lightning. Hoping for headshots is a cope, so nothing that relies on them is used here. Multishot reportedly does not generate more lightnings, hence I didn't use it either. [Gyre]'s crit buff should be doing some work here. If you have [Primed Shred], which I very much don't have, that might as well be enough punch through and you could drop Metal Augur in favor of [Heavy Caliber], to simply do more damage. It's not like you need accuracy to hit a ball of 10 dudes, but I still included [Stabilizer], because this rifle kicks too much for my taste. That's a matter of preference I suppose and you can use [Vigilante Supplies] and cope you will one day see the 5% big crit :D.
