Modern Warfare 3 and Warzone Season 5 is shaping up to be one of the best seasons yet, thanks to the return of fan-favorite weapons like the STG44, the release of the final Story Mission for Modern Warfare Zombies, and the introduction of the chaos-infused mode, Supreme Resurgence, for Warzone. Although some time has passed since the latest Season 5 Reloaded update, new content updates continue to roll out. For players looking to get an extra Aftermarket Part, make sure to grab the JAK Deathmarch and add it to your arsenal.

The JAK Deathmarch is an Aftermarket Part for the BAL-27 Assault Rifle. This Conversion Kit transforms this typically fully automatic weapon into a laser burst rifle, allowing it to fire five-round bursts for massive damage. While this Aftermarket Part is not the best of Season 5's array of additional attachments, it can still be quite fun to use with the right loadout and build.

The JAK Deathmarch Aftermarket Part is one of the weekly rewards available in Modern Warfare 3 and Warzone Season 5. To unlock it, players must complete 5 out of the 7 Week 6 Challenges, which vary across Multiplayer, Zombies, and Warzone modes. Each challenge also offers a hefty XP reward, and unlocking the JAK Deathmarch Aftermarket Part brings players closer to earning the Chainbreaker Camo. To view the Weekly Challenges, go to the Launcher Menu, select Challenges, and navigate to the Weekly tab.

The JAK Deathmarch will shift to the Armory Unlock section after the debut of Season 6.

The JAK Deathmarch BAL-27 isn't exactly a meta option in Season 5's lineup of new weapons and attachments. However, the gun can be built similarly for both Modern Warfare 3 and Warzone, as it's primarily tailored for close-to-medium-range engagements. Players may want to prioritize boosting attributes like sprint-to-fire speed, aim-down-sight speed, and mobility to compete with some of the best meta weapons in the game. The build below accomplishes this, providing players with a weapon capable of eliminating unarmored opponents or breaking full armor plates with just one shot.

  • XTEN Phantom-5 Handstop (Underbarrel)
  • FSS OLE-V Laser (Laser)

Best Equipment For Modern Warfare 3

The best Equipment for the JAK Deathmarch BAL-27 differs significantly from some of the top Assault Rifle loadouts in the game. The Infantry Vest is a no-brainer, allowing players to Tactical Sprint much longer for added mobility on the battlefield. Other equipment to consider includes Quick-Grip Gloves and Stalker Boots, a combo that boosts weapon swap speed, strafe speed, and ADS movement speed. The last two pieces of equipment are also quite effective: the Bone Conductor Headset helps players better hear enemy footsteps, which is great for prefiring to mitigate the JAK Deathmarch's charge-up time, and the Mag Holster provides faster reload speeds.

Best Perk Package For Warzone

Our top picks for the best Perks to pair with the JAK Deathmarch BAL-27 are carried over from some of the best Warzone loadouts because of their versatility. Double Time and Sleight of Hand are particularly valuable for extending Tactical Sprint duration and reducing reload times. Tempered is another great choice, often swapped out for Quick Fix, due to its ability to reduce armor plate consumption. Finally, Birdseye can be a perfect fit for an aggressive playstyle, revealing Ghosted players on the minimap during UAV usage.

  • Double Time
  • Sleight of Hand
  • Tempered

Secondary Recommendations

The JAK Deathmarch BAL-27 is not exactly the most reliable go-to weapon, largely thanks to its slow charge-up time with each burst short. Players will also find the weapon burning through its ammunition fairly quickly, calling for players to make use of a reliable swap-to-Secondary. A weapon from the Handgun category is a great choice for Core Multiplayer, with the WSP Stinger remaining the top pick for Season 5, though the Renetti and the TYR are also good options.

For Battle Royale, on the other hand, the JAK Deathmarch is best paired with one of Warzone's powerful Sniper Rifles to cover long-range engagements. For Warzone Season 5, the KATT-AMR remains the top choice in the Sniper category, but the XRK Stalker and the MORS are also strong contenders. For players looking for a more fast-paced Sniper substitute, the Kar98K from the Marksman category is a good option.
