Barrel attachments in MW4
Data updated · Latest official patch:
Modern Warfare 4 lists 104 community-reported barrel attachments. Each has its own page below. Activision's weapon sheets give 28 weapons a barrel slot. CODMunity lists stat changes for 104 of them. Adjusts damage range, bullet velocity and other ballistic traits.
Community-reportedNames, weapons and stat changes from community sites, read November 4, 2026: community-reported and unverified.
Strongest reported effects of barrel attachments
These come from CODMunity's game data (read November 4, 2026). Each line names the attachment and weapon with the largest reported change to one stat, as a percentage of that weapon's own value, so two weapons with different base values are compared by percent only. Lines marked better move the stat in the direction that helps the player; lines marked worse show the largest cost.
