Call of Duty: Modern Warfare 3’ssecond season has a new set of weekly challenges that will release over the next eight weeks. Each week, 21 new challenges will become available to complete in MW3’s three core modes: Multiplayer, MWZ, and Warzone.

Completing any five of these challenges—either in one mode or a mix of all three—will unlock a new attachment, conversion kit, or even a weapon. The first set of challenges available this season is currently available, along with a new conversion kit for one of Modern Warfare 3’s most popoular sniper rifles: the Longbow.

Modern Warfare 3 Longbow JAK Tyrant 762 Kit

Week 1 Challenge Reward

Completing five challenges this week will award theJAK Tyrant 762 Kitforthe Longbow sniper rifle. This is a conversion kit that modifies the receiver to accept 7.62 BLK ammunition.Each shot deals 17% more damage, but your effective range and bullet velocity stats are cut in half.The attachment sacrifices the Longbow’s long-range potential for slightly more powerful rounds at close range.

The damage difference makesno TTK difference in Multiplayer, so this attachment is more or less a straight downgrade. However,the extra damage makes it a solid two-shot option for Warzone.If you want a sniper rifle with high handling and moderate damage, this conversion kit might interest you. For everyone else, this is a safe skip.
