The JAK Patriot Kit allows you to convert MW2’s M16 into a full-auto assault rifle, complete with MW3 recoil and minimal gun smoke. It’s the definitive assault rifle for players who prefer accuracy over raw stopping power.

This guide will go over how to get your hands on the JAK Patriot Kit this week through the Weekly Challenges system. We’ll briefly go over how the JAK Patriot Kit works and cover the fastest ways of completing each of this week’s challenges. You only need to complete five to get your hands on this weapon, and they can be from any playlist.

Week 7 Challenge Reward

This week’s challenge reward is theJAK Patriot Kit for the M16, converting the burst rifle into a fully automatic assault rifle. Compared to the M4, the M16 trades raw damage for significantly better recoil control. It handles more like an MW3 assault riflethan a traditional MW2 weapon, so expect significantly less gun smoke and visual recoil while firing.

This conversion kit locks your barrel attachment.

Each round deals 32 damage to the body and 41 damage to the head; no limb modifiers are present. The in-game HUD states that the M16 fires at 596 RPM, but based on limited testing, it appears to have a slightly slower fire rate than the M4. Build this weapon for recoil mitigation, and it becomes one of MW3’s most accurate assault rifles, ideal for Warzone players.
