Methodology

All weapon stat changes are sourced from official Treyarch patch notes published on callofduty.com/patchnotes. Where Treyarch publishes a multiplayer-specific note we use that as canonical. Where MP changes are bundled inside a Warzone-titled note, we flag the entry with reduced confidence and cross-reference community sources to confirm MP applicability.

• MODE · Multiplayer only. Warzone / Zombies / Campaign excluded.
• WINDOW · Black Ops 7 launch through the most recent published patch.
• ITEMS · Weapons (ARs, SMGs, Shotguns, LMGs, Marksman, Snipers, Pistols, Launchers, Specials, Melee). Expanding to Scorestreaks, Field Upgrades, Lethals, Tacticals, Perks, and Equipment.

Every numerical change is classified along three axes:

• Direction

  buff, nerf, neutral, mixed, or qualitative (text-only without numerical change).

• Magnitude

  small (<5%), medium (5–15%), large (15–30%), overhaul (>30% or rework).

• Confidence

  high (canonical MP patch note), medium (Warzone-titled note with MP applicability), low (community-reported, awaiting confirmation).

A weapon's cumulative delta is the sum of every numerical change applied since launch. Reworks (when Treyarch substantially restructures a weapon) reset the baseline — a post-rework weapon is treated as a fresh entity, not as continuing deltas from the pre-rework version. Attachment-level changes are tracked separately and do not roll into the base weapon's cumulative delta.

• Reproduce Treyarch's prose verbatim. Every change description is paraphrased.
• Predict future changes or speculate on Treyarch's intent.
• Track community tier rankings — only objective stat deltas.
• Track third-party balance mods or playlist-specific tuning.
