Week 2 Challenge Reward

This week’s reward is theJAK Requiem Kit forthe Kastov 762and 545.While equipped, the kit completely removes vertical recoil and substantially reduces your horizontal recoil. In other words,your weapon has no recoil.This somewhat makes up for the poor TTK values for the MW2 Kastov weapons.
