Sources & coverage
This is an independent fan-made planner for Call of Duty: Modern Warfare 4 (2026). It is not affiliated with Activision or Infinity Ward. Game names, weapon artwork and camo reference images belong to their respective owners. The interface is an original implementation inspired by the in-game Gunsmith.
What the planner covers
All 33 launch weapons, 28 customizable firearm measurement sets, compatible attachment types, a five-slot limit, separate Apex restrictions and 17 official completionist, mastery and weapon prestige camo examples. Season 1 weapons, all military camos and weapon-specific special camos are not yet catalogued.
Weapon and camo photographs are official references. Selecting an attachment updates choices and projected stats; it does not render a new attachment model. Camo examples show the HAN 86, including when another weapon is selected. Animated camos are represented by stills. No arbitrary 3D model, exact assembled-weapon render or live account inventory is supplied.
Official data
- Activision: launch weapons and Create-a-Class — 33 launch weapon specifications, allowed slots and Apex exclusions.
- Activision: progression and camos — official camo names and reference images. Use the official guide for unlock requirements.
- Official Season 1 patch notes — check for changes made after measurements were recorded.
Official launch references checked November 14, 2026. Magazine, reserve and fire rate in the launch specifications are preserved as published, even where community measurements differ.
Community measurements and estimates
RankKD’s public weapon tool supplies community stock and single-attachment measurements. Its dataset records testing on November 1, 2026, with later patch notes. A test date is shown for each weapon. These measurements are not Activision data and have not been independently reproduced in our firing range.
For each stat, the planner multiplies the stock value by the ratio of each isolated attachment value to stock. A single attachment reproduces its recorded source value. Multiple attachments are a projection; the game may combine or cap effects differently. If the stock value is zero, listed values are added. An unlisted numerical effect is left unchanged rather than invented. Ratings may exceed a bar’s visible 0–100 range; the detailed number is preserved.
Damage, range, accuracy, mobility and handling are Gunsmith ratings. Damage rating is not damage per bullet. Recoil units are as reported by the source. No TTK, damage-range simulation or claim of a competitive “best build” is made. Use the game to confirm an important setup after balance patches.
Saving and sharing
Builds and notes are kept in this browser. Export JSON to keep a backup. Share links include the complete build and notes in the URL fragment; anyone with that link can read them. No game sign-in is needed.
Updates and corrections
Catalogue version: November 14, 2026. Coverage gaps and differing source values are retained visibly rather than filled with guesses. New measurements need a dated source before they are added.
