Season 1 Reloaded in Modern Warfare 3 is in full swing, but there’s a pesky bug causing frustration among players attempting to unlock the new TAQ Evolvere LMG through the Week 7 challenge. If you’ve been left scratching your head wondering why your progress isn’t counting for the ‘Get 30 Operator Kills with AOK 4.0x RQ-9 Recon Equipped to a Recommended Weapon’ challenge, worry not – I’ve found a fix!
MW3: How to Fix the Week 7 Challenge Bug

The solution to this bug is surprisingly simple. Instead of using the specified AOK 4.0x RQ-9 Recon, equip the KR Intlas LSJ-3 Optic (pictured above) on a Recommended Weapon to rack up those 30 kills in Multiplayer. While there might be other optics that work, my kills with the KR Intlas LSJ-3 equipped on my Holger 556 counted towards the challenge progress.
This ‘bug’ appears more like a typo from the developers’ side than a game glitch or coding error. Considering three out of seven challenges in Week 7 involve the ‘JAK’ aftermarket parts, it’s plausible that the developers intended to write ‘JAK’ instead of ‘AOK’ for this specific challenge, too.
While it’s just a theory, it aligns well with the fact that the KR Intlas LSJ-3 is an aftermarket part unlocked by completing any 5 Challenges from Week 4.
And there you have it, folks—that’s the fix for the MW3 Week 7 Challenge bug that has been causing headaches for many players, myself included! For more to-the-point guides and the latest news updates on your favorite games, stay tuned to Gamer Haul!
Thats not working for me. Also on the challenge it shows in 13/30. And I got that before I even unlocked the scope everyone is saying is the fix. I’ve tried it with smg, and assault that are recommended but its not moving. Its my only hope I never get first kill and it would take me forever to level up the tyr
Have you tried equipping the Optic on the Holger 556 and see if that works?
Edit: I had a quick look at the subreddit, someone commented: “After switching from AOK to KR from reading this thread, then back to AOK, kills are registering.” Give it a try!
