Cripple Leg and Cripple Arm have a hilarious interaction with mutated guns currently, if you have mutated any other weapon into a gun it will gain double damage, I suspect this has something to do with the change to cripple leg a while back that let it gain scaling for guns specifically.

To replicate, obtain any mutated gun (I used a mutated Qinglongram in this case), and then cripple arm/leg a target, you'll notice it does double damage compared to a regular basic attack.
