Season 2 of Modern Warfare 3 has gone live and the first conversion kit to make an appearance is the JAK Tyrant 762 Kit. If you want to turn the Longbow into a sniper rifle with some serious potential, I can outline exactly how to unlock it for your collection.
How to Get the JAK Tyrant 762 Kit in MW3
To unlock the JAK Tyrant 762 Kit, you need to complete at least five of the Weekly Challenges from Week 1 in Season 2. There are 21 Weekly Challenges in total that are split between the main modes for MW3: Multiplayer, Modern Warfare Zombies, and Warzone. You can choose to focus on one mode or split your time for the best results.
