JAK Volkh

The JAK Volkh is available for the KV Inhibitor sniper rifle and allows it to fire a two-round burst instead of a single shot. The burst enhances damage output and with minimal dispersion, accuracy is key when using the aftermarket part in the heat of battle.

JAK Scimitar

The JAK Scimitar for the FJX Horus SMG improves its range and recoil alongside providing the weapon with a huge drum magazine that's perfect for eliminating multiple opponents without having to reload regularly.

JAK Thumper-656

The RGL-80 grenade launcher has received an upgrade. The JAK Thumper-656 adds a long barrel onto the launcher in addition to an increase in bullet velocity. 

JAK Requiem

Modern Warfare 2's Kastov 762 receives an upgrade in the form of the JAK Requiem. Designed to completely eradicate vertical recoil, this aftermarket part could prove extremely popular for those wanting a laser beam of an assault rifle.

JAK Decimator

Sticking with Modern Warfare 2's weaponry is the JAK Decimator which is available for the Lachmann Shroud. This converts the burst fire to fully automatic, enabling players to shred through anyone in close-quarters combat.

JAK Intimidator

Lastly, the JAK Intimidator arrives as an upgrade to the popular Renetti pistol. This aftermarket switches the burst fire to semi-automatic, giving players additional precision when firing the weapon at longer distances. Up close and personal, it's easy to make an impact for those who have a quick trigger finger.
