Call of Duty: Modern Warfare 3is delving into science fiction territory with some of its Season 5 conversion kits. The JAK Deathmarch Kit for the BAL-27 turns this assault rifle into a five-round burst laser rifle. Bursts from this weapon have virtually instant projectile speed and deal high damage, but you need to handle the gun’s immense recoil to make good use of it.
The good news is that hipfire builds are quite powerful with this BAL variant, and it’s fairly easy to create. Let’s go over how the JAK Deathmarch Kit works, how to unlock it, and cover the strongest hipfire build you’re able to use on this weapon.

How To Unlock The JAK Deathmarch
The JAK Deathmarch Kit is theWeek 6 challenge rewardin Season 5.You need to complete any five challenges from the Week 6 challenge set. This can be a mix of challenges from Multiplayer, MWZ, and Warzone.
Once Season 5 ends, you can unlock this conversion kit fromthe Armory Unlocks system.
You’ll also need to own the BAL-27 to use the JAK Deathmarch Kit. As with most MW3 weapons, the BAL-27 is tied to Armory Unlocks, requiring five daily challenge completions.
Hipfire JAK Deathmarch Build
TheJAK Deathmarch Kitturns the BAL into a shotgunwith a pre-charge delay, similar to how fusion rifles work in Destiny. You’ll need to hold down the trigger for a short duration before the burst fires, so you’ll want to prefire enemies when possible. The good news is thatyou can charge the gun mid-slide,so we’ve built this loadout to emphasize sliding as much as possible. The kit also has great hipfire accuracy, so we might as well spec for hipfire play.
We highly recommend you equip theVerdant Hook Box Laserfor this build, as it retains most of your accuracy while sliding. Without it, you’ll struggle to hit enemies past five meters mid-slide. For hipfire accuracy, we use theBruen Bastion Angled GripandTidal Tac Gripto lower our spread deviation to 1.3 degrees, which is just as accurate as most tac stance builds. We then use theClarent Light Stockto buff the weapon’s mobility and ADS stats.
Loadout Recommendations
The BAL-27 has a fairly long sprint-to-fire delay, so we aim to fix that with theInfantry Vest.Running Sneakers are given for free with this vest, reducing your sprint-to-fire delay when coming out of tactical stance. We also run theCommando Glovesto reduce sprint-to-fire timings in general. We then runCompression Platefor HP regeneration on kills andTac Maskto resist enemy tactical grenades.
Equipment on this build is dealer’s choice. An aggressive playstyle will likely perform best withStimsand theMed Box, giving you options for rapidly healing in combat.
