KV Broadside Attachments: Practical Warzone Builds and the JAK Jawbreaker Trade-Off

The KV Broadside is a Call of Duty shotgun, not a heavy tank. Its useful upgrades are Gunsmith attachments and, in some versions, the JAK Jawbreaker conversion kit. A sensible setup depends on your game mode, patch, preferred engagement distance, and whether you want conventional semi-automatic shotgun behavior or the conversion’s fully automatic .458 SOCOM configuration. The attachment combinations below are documented third-party examples, not an official or permanently current best-in-slot verdict.

First, correct the “heavy tank” mix-up

Search results for the exact phrase combine two unrelated ideas. The KV Broadside described by the topic-specific sources is a Call of Duty weapon. It is not a military vehicle, a tank component, or a physical product that can be upgraded with real-world parts.

As an Amazon Associate I earn from qualifying purchases.

That distinction matters because a physical tank attachment, miniature conversion kit, or firearm component cannot modify a digital KV Broadside. The recommendations in this guide apply to the in-game weapon and its Gunsmith configuration. If you meant a real heavy tank or a tabletop model, you need a different subject and parts list.

Attachment names and effects can change with the game, mode, season, and balance patch. The sources available for this guide include third-party loadout pages and a fan-maintained reference, but they do not establish the current official unlock path or live balance values. Check the attachment descriptions in your installed game before committing a build.

What determines a good KV Broadside build?

There is no universally best five-attachment combination in the available evidence. Choose around the way you actually use the weapon:

  • Close-range responsiveness: prioritize a setup that feels quick when sprinting, turning, and firing from the hip.
  • Range and consistency: use the source-reported barrel, laser, and ammunition options that are intended to improve reach or pellet behavior, while accepting possible handling costs.
  • Capacity: a larger magazine reduces the number of reloads during a fight but can make the gun slower or less comfortable to handle.
  • Hip-fire versus aimed fire: a laser-oriented setup suits players who fire immediately from the hip; a more deliberate player may value a steadier, longer-range configuration.
  • Weapon identity: the standard KV Broadside remains a shotgun, while the JAK Jawbreaker changes its firing and caliber configuration and removes several normal attachment choices.

The cited pages do not provide a controlled test between these choices. Treat their combinations as practical starting points and source-reported guidance, not measured proof that one build outperforms every alternative.

A current-looking Warzone build example

A Warzone Loadout listing gives the following five-attachment example for the KV Broadside:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
Slot Attachment What this choice is intended to address
Barrel Gunner D20 Part of the listing’s overall range and handling setup
Magazine 12 Shell Mag Provides a defined shell capacity for the build
Laser Verdant Hook Cylindrical Supports the build’s close-range aiming and hip-fire role
Ammunition 12 Gauge Dragon’s Breath Changes the ammunition behavior within the listed shotgun setup
Bolt Dashbolt 60 Completes the listing’s firing-cycle configuration

This is one third-party build example, not an official endorsement or a verified best-in-slot result. The page was crawled for the topic, and its recommendations should be checked against the attachment names and stat bars shown in your current game. If a slot is unavailable in your mode or the displayed effects differ, use the in-game description as the authority.

When this example makes sense

Use this combination as a starting point when you want a conventional KV Broadside setup that covers barrel, magazine, laser, ammunition, and bolt slots together. It is most useful for a player who wants to experiment with a defined five-part configuration rather than tune one statistic in isolation.

Before deploying it, fire several engagements at the distances you normally encounter. Pay attention to the time required to aim, the spread of hip-fire shots, the number of shells available before reloading, and whether the ammunition’s behavior fits your range. Those are practical checks, not claims of a laboratory result.

Older Warzone 2 guidance: what remains useful and what does not

A Pro Game Guides article from 2023 recommends a different configuration:

Slot Attachment
Barrel ZLR Sport-8
Laser Point-G3P 04
Modification Stockless
Bolt Dashbolt 60
Magazine 12-round magazine

The same guide discusses a 25-shell drum as a capacity option with a mobility and handling cost. That article is historical 2023 guidance for Warzone 2, so it should not be presented as the current meta without rechecking the live game. Its value today is as a decision example: more shells can help when several opponents arrive together, but the added capacity is not free.

How to use the older build as a test plan

  1. Recreate the five listed parts only if your current Gunsmith still offers the same names and slots.
  2. Run a short close-range test with the 12-round magazine and note how quickly you can aim, fire, and move after sprinting.
  3. If your mode offers the 25-shell drum, compare it in separate matches rather than changing several other parts at once.
  4. Keep the drum only if the extra capacity solves a real reload problem; remove it when the mobility or handling penalty causes more lost fights than reloads would have.

This method separates the magazine trade-off from the rest of the build. It does not establish a universal damage or time-to-kill advantage, because the cited material supplies no controlled measurements.

JAK Jawbreaker: a different weapon configuration

The Call of Duty Wiki’s fan-maintained entry describes the JAK Jawbreaker as a conversion that locks the KV Broadside into fully automatic fire and changes its caliber to .458 SOCOM. The entry also says that equipping it blocks modification of the ammunition, barrel, magazine, and bolt slots.

That is a fundamental change, not a minor attachment swap. You are trading the flexibility of a normal shotgun build for a defined automatic configuration. The source is community maintained rather than official current documentation, so verify every effect, blocked slot, and unlock requirement in the live game.

What the conversion changes in practice

  • Firing mode: the weapon is described as fully automatic instead of retaining the normal semi-automatic behavior.
  • Caliber: the listed conversion changes the configuration to .458 SOCOM.
  • Build freedom: ammunition, barrel, magazine, and bolt modifications are reported as unavailable while the conversion is installed.
  • Decision: select it when the automatic configuration is more important to you than tuning those four slots independently.

Do not combine the JAK Jawbreaker description with the five-part conventional build as though all of the slots remain interchangeable. The conversion’s reported restrictions are the reason it belongs in a separate decision branch.

Choosing between the conventional shotgun and the conversion

Priority Better starting point Reasoning
Customize barrel, ammunition, magazine, and bolt Conventional KV Broadside The reported JAK Jawbreaker restrictions remove those choices.
Try fully automatic fire JAK Jawbreaker The fan reference describes it as locking the weapon into automatic fire.
Keep a shotgun-oriented role Conventional KV Broadside The conversion is described as a .458 SOCOM configuration rather than the standard shotgun setup.
Use the largest available shell reserve Conventional build with a compatible larger drum The 2023 guide describes the 25-shell drum, but also reports mobility and handling costs.
Follow a fixed conversion identity JAK Jawbreaker Its defining benefit is the automatic, changed-caliber configuration rather than slot-by-slot tuning.

This comparison describes the choices reported by the cited references. It does not claim that one branch has a higher current damage output or faster elimination time.

How to equip and validate a build

Menu labels vary between Call of Duty releases and updates, but the workflow is consistent: select the weapon in a loadout, open its Gunsmith, choose an attachment slot, and confirm the displayed changes. Use the following order so that one change does not hide the effect of another.

  1. Confirm the game and mode. Write down whether you are building for Warzone, an older Warzone 2 ruleset, or another Call of Duty mode. The 2023 configuration should not be assumed to describe a current mode.
  2. Check the weapon name. Make sure the selected item is the KV Broadside shotgun, not a similarly named weapon or a vehicle-related item.
  3. Decide on the branch. Build the standard shotgun first if you want access to barrel, ammunition, magazine, and bolt choices. Choose the JAK Jawbreaker only after reading its current in-game restrictions.
  4. Add one attachment at a time. Start with the barrel, then laser, magazine, ammunition or modification, and bolt. Record the stat-bar movement and any handling change shown by the game.
  5. Check compatibility. If a slot disappears after installing the conversion, do not try to force a conventional attachment into it. The reported conversion behavior intentionally constrains those slots.
  6. Test the intended distance. Fire at the range where you expect to fight. Test both hip-fire and aimed shots if your build includes a laser or a range-oriented barrel.
  7. Test movement and reloads. Sprint, slide or otherwise use your normal movement, then reload under pressure. This exposes the practical cost of a heavier magazine or a handling-focused choice.
  8. Recheck after updates. Attachment availability, names, and balance can change. The absence of official current patch documentation in the cited material means the live in-game screen is the final check.

Common mistakes and how to fix them

Treating the title as a real tank-upgrade question

No evidence in the cited material supports a physical tank part that upgrades a KV Broadside. Fix the mismatch by returning to the Call of Duty loadout and Gunsmith context. Do not buy or install real hardware for a digital weapon.

Calling a 2023 guide the current meta

The Pro Game Guides configuration is explicitly older Warzone 2 guidance. Use it as a historical template, then confirm every attachment and stat in the current mode. If the slot or name has changed, stop copying the old list and rebuild around the current options.

Assuming a larger magazine is automatically better

The 25-shell drum is described as increasing capacity while reducing mobility and handling. If you rarely empty the standard magazine, the extra shells may add more cost than value. Keep it when your fights genuinely run long enough to justify the reserve.

Adding normal attachments after installing the conversion

The fan reference says the JAK Jawbreaker blocks ammunition, barrel, magazine, and bolt modification. If those slots are locked, that is a reported property of the conversion, not a missing unlock that can be solved by repeatedly changing menus.

Expecting a source-reported build to guarantee performance

Neither cited build page supplies a controlled comparison, and no named performance statistics were established. Treat each list as a starting configuration, then judge it with your own movement, range, reload, and hit-consistency tests.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Which build should you start with?

For a conventional shotgun experiment, start with the Warzone Loadout combination of Gunner D20, 12 Shell Mag, Verdant Hook Cylindrical, 12 Gauge Dragon’s Breath, and Dashbolt 60, provided those parts are available in your mode. It covers the main Gunsmith categories without claiming to be an official best-in-slot setup.

Use the Pro Game Guides list only as a historical alternative: ZLR Sport-8, Point-G3P 04, Stockless, Dashbolt 60, and a 12-round magazine. Its 25-shell drum discussion is useful for understanding capacity versus mobility, not for proving a current advantage.

Choose JAK Jawbreaker when the reported fully automatic .458 SOCOM configuration is the feature you want and you accept the loss of ammunition, barrel, magazine, and bolt customization. Because that information comes from a fan reference, verify the conversion’s current behavior and requirements before spending unlocks on it.

What is still uncertain

The available references do not establish an official, current attachment-unlock list, a complete balance history, or measured comparisons between the listed builds. They also do not provide attributable quotations or reliable performance statistics. Those gaps are why this guide presents named combinations, trade-offs, and verification steps rather than promising a universal damage, range, or time-to-kill result.

When the in-game attachment screen conflicts with an older guide or community entry, follow the current in-game description and patch information for your installed version. Mode, platform, season, and regional rollout can affect what you see.
