Call of Duty: Modern Warfare 3has released its sixth set of weekly challenges during its first season. Each week, a new series of challenges are added to Multiplayer, MWZ, and Warzone. Completing a total of five challenges across all three modes will award a new attachment, aftermarket part, or even a new weapon.
This week’s challenges encourage players to use the AMR9 SMG and any MW3 LMG. Complete enough challenges, and you’ll be awarded with the double-barrel conversion kit for the AMR9. This guide will cover every challenge added this week, give some tips on how to best complete each one, and briefly explain how the AMR9 conversion kit works.
Week 6 Challenge Reward
This week’s reward isThe EttinAftermarket Part. This is a conversion kit forthe AMR9 SMGthat installs a second barrel onto the weapon, converting the weapon into a two-round burst SMG that fires its bursts automatically. In other words, it behaves identically to the base version with an added burst delay (roughly 7ms).
Unfortunately, this attachment offers no RPM boost, damage changes, or notable accuracy improvements. This conversion kit actuallyreducesyour accuracy significantly, adding some serious accuracy deviation with each shot. It’s nigh-unusable past 25 meters, even with multiple accuracy attachments installed. In general, we recommend you avoid using this attachment.
