The third week of challenges for Call of Duty: Modern Warfare 3's first season is now live, offering players a clear path to unlock a potent new tool for their arsenal. This week's focus is on securing the JAK Beholder Rifle Kit, a powerful conversion kit designed for the Tyr revolver. The challenges themselves are considered relatively straightforward, primarily revolving around securing eliminations with the Rival-9 submachine gun across the game's various modes. For players already comfortable with SMG gameplay, the journey to unlock this unique Aftermarket Part should be a smooth one. This guide provides a comprehensive breakdown of all weekly challenges for Multiplayer, Zombies, and Warzone, along with an updated analysis of the Tyr's new rifle configuration based on recent testing.

Week 3 Challenge Reward: JAK Beholder Rifle Kit

The ultimate prize for completing this week's set of challenges is the JAK Beholder Rifle Kit for the Tyr revolver. This conversion kit fundamentally alters the weapon's profile and performance. It equips the Tyr with a custom 3D-printed barrel and stock assembly, which results in a dramatic reduction in recoil and a significant boost to effective range. Statistically, the kit extends the weapon's effective damage range out to approximately 19 meters and doubles its bullet velocity. However, this specialization comes with a trade-off: while the kit is equipped, players cannot attach any other barrel modifications. The newfound stability and range make the Tyr an excellent platform for high-magnification optics and specific underbarrel grips. It doesn't quite reach the power of a dedicated sniper rifle, but the JAK Beholder Kit successfully transforms the Tyr into a formidable hybrid, bridging the gap between a sidearm and a marksman rifle.

Challenge XP Reward Key Tips
Open 50 loot caches. 2,500 XP Land in high-density areas like Popov Power or Seaport.
In Urzikstan, get 10 kills in the northwest region (Resort, Power, Seaport, Cargo). 5,000 XP Play Resurgence or Plunder modes. Respawning modes make kill challenges far easier.
In Urzikstan, get 10 kills in the southern region (City, Suburbs, Manor). 5,000 XP Play Resurgence or Plunder modes.

🌍 Pro Tip: For all the region-specific kill challenges, avoid standard Battle Royale. The Resurgence and Plunder game modes are vastly more efficient, as they feature frequent respawns and constant action, allowing you to quickly farm the required 10 kills in each designated area without the pressure of permanent elimination.

Final Thoughts and Strategy

Completing the Week 3 challenges is a rewarding endeavor for any Modern Warfare 3 player looking to expand their weapon options. The JAK Beholder Rifle Kit offers a novel and effective playstyle for the Tyr, making it a versatile choice for medium-range engagements. The most efficient overall strategy involves focusing on one mode at a time and using the Rival-9 as your primary weapon wherever possible. In Multiplayer, remember your Quick-Fix Gloves for the weapon swap challenge. In Zombies, come prepared with a crystal to supercharge your grind. In Warzone, let the chaos of Resurgence work in your favor for the location-based objectives. By following these focused approaches, players can efficiently claim their new conversion kit and add a powerful hybrid weapon to their loadouts.
