Strongest reported effects of muzzle 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.
