Not sure what to say about this kitgun, I love it. Get the pax [Seeker] going and everything drops around you.
The riven in the primary version of the kitgun gives so much better stats than when used in a secondary catchmoon.

Secondary Riven stats:
Critical Chance: 84.6%
Damage: 136.2%
Damage to corpus: -11.3%

Primary Riven stats:
Critical Chance: 177.6%
Damage: 286.1%
Damage to corpus: -23.6%

If you dont have/want to use faction mods then replace with [Serration].

This is the same riven just the secondary and primary versions of the stats, this gives 1.2m DPS damage, 167.2% Critical Chance and 7.1 critical damage multiplier with conditionals applied.

Take your rubbish [Catchmoon] riven and make a crazy [Catchmoon] primary with it.
