JAK Headhunter Carbine Conversion

The JAK Headhunter Carbine Conversion is a conversion kit for the Rival-9 submachine gun featured in Call of Duty: Modern Warfare III as part of the Aftermarket Parts system. It was added as part of the Season One update.
It converts the Rival-9 into a three-round auto-burst, increasing damage, bullet velocity, range, and recoil control at the cost of mobility and rate-of-fire.
