Week 1 Challenge Reward

Modern Warfare 3 Rival-9 Headhunter Carbine Conversion Kit Preview

Completing five challenges this week will award the JAK Headhunter Carbine Conversion Kit, transforming the Rival-9 SMG into a three-round burst rifle. The attachment increases the weapon’s base damage to 33 per shot, extends its minimum damage falloff by 25%, and greatly reduces the Rival-9’s recoil. All of these benefits come at the cost of handling stats and the Rival-9’s fire rate.
