The MXR-17 ANVL Conversion is a brand-new barrel attachment for the MXR-17 assault rifle in Black Ops 7 and Warzone. This attachment is part of the Season 2 Reloaded content and is now available as the ultimate reward for the Season 2 Week 7 Challenges.

When you equip this attachment, the assault rifle transforms into an LMG. It features a big magazine and a unique firing mechanism where the initial shots fire extremely fast but come with high recoil. However, as you keep firing, the weapon becomes steady and accurate.

This article outlines the exact unlock criteria for the MXR-17 ANVL Conversion barrel attachment in Black Ops 7 and Warzone.

How to get the MXR-17 ANVL Conversion barrel attachment in Black Ops 7 and Warzone

To unlock the MXR-17 ANVL Conversion barrel attachment you need to complete any six tasks from Warzone and Black Ops 7 Season 2 Week 7 Challenges.

There are 24 tasks present in the weekly challenges, featuring six challenges for each of the major modes: Co-op Campaign (Endgame), Multiplayer, Zombies, and Warzone.

Your only requirement is to complete six tasks, irrespective of any order or sequence. You do not need to stick with any single mode; you can easily mix and match different tasks from different modes. So, simply go through the list provided below, find the six easiest based on your personal preference, and complete them quickly to unlock the new barrel attachment for the MXR-17 assault rifle.

However, if you are strictly a Warzone-only player, you will need to complete the entire Warzone set, as you will not have access to other modes. But do not worry as the casual mode makes it much easier to complete these challenges, as this specific mode features far easier enemies.
