How to use the Unlock All Attachments Glitch in MW3 and Warzone

The early stages of a new weapon can be a bit rough due to the limitations of Gunsmith items. Although you’ll claim these tools later on, it can sometimes take a while with the more advanced levels. So, to quicken the pace, here’s how to use the Unlock All Attachments glitch in MW3 and Warzone.

Unlock All Attachments Without Leveling Up Glitch in MW3 and Warzone, explained

To unlock all attachments without leveling up in Warzone and MW3, customize a gun in a Private match. The weapon must be unlocked first in Multiplayer or Warzone, as the Base version is required. For example, if you haven’t completed three Daily Challenges for the TAQ Evolvere, you won’t be able to utilize the glitch for this gun’s attachments.

Once you have a weapon in mind, go to the Private Match section in either the Warzone or MW3 Playlist. Now, select the Weapons section and customize the gun with any attachments. Private Matches provide access to the entire catalog, regardless of whether it is locked in the Public Playlists. Press ‘Save a Custom Mod,’ which is shown in the bottom-left corner.

Exit the Private Match and select a public game in Warzone or MW3. Go to the Weapons section, and the saved custom mod should now be available in the Gunsmith section. This allows you to access all attachments without leveling up, even if the Base version doesn’t include these tools. I tried it out with my previous locked items and had no problems when diving into a match.

The glitch for unlocking all attachments has appeared throughout Call of Duty’s timeline. However, it does seem to get patched after some time. With MW3 and Warzone Season 3’s launch, the glitch has come up again now that the game has been updated. The trick could eventually be patched, so just bear that in mind for the future.
