The fifth week ofCall of Duty: Modern Warfare 3’sfirst season has introduced the JAK Signal Burst Conversion Kit to the sandbox. This is an Aftermarket attachment that converts the Holger 556 into a four-round burst gun, capable of killing an enemy player with one burst.
Obtaining this attachment will require you to complete five weekly challenges added this week, most of which revolve around Holger 556 kills. This guide will explain how the Holger 556’s JAK Signal Burst Conversion Kit works, and we’ll give tips on how to complete every weekly challenge for Multiplayer, Modern Warfare Zombies, and Warzone.
Week 5 Challenge Reward
Completing five of this week’s challenges will award theJAK Signal Burst Conversion Kit for the Holger 556.This turns the Holger into a four-round burst rifle, sacrificing handling stats for a slightly faster TTK. It also comes with built-in optic and laser attachments. You cannot install barrel or laser attachments onto this conversion kit, but optics are fair game.
Since the Holger can kill an enemy with four rounds to the chest, the JAK Signal Burst can one-burst targets in Multiplayer, making it a strong alternative to the FR 5.56 and DG-56. Firing aim stability seems to be quite low on this conversion kit, so be sure topair this Aftermarket part with a few accuracy attachments.
