The KV Broadside is a Call of Duty shotgun, not a heavy tank. The tank wording in the supplied title appears to combine two unrelated subjects. The attachment advice below therefore treats the KV Broadside as the semi-automatic shotgun described by the available game references.
There is no verified, current official attachment tier list in the available material. The builds are third-party examples, and the JAK Jawbreaker details come from a fan-maintained reference. Use them as starting points, then confirm slot names, unlocks, and statistics in your installed game and current patch.
What the KV Broadside is—and what it is not
The KV Broadside is identified in the available Call of Duty material as a semi-automatic shotgun. It is not a heavy tank, tank component, or physical firearm upgrade. That distinction matters because an in-game Gunsmith attachment changes a digital weapon; no real-world barrel, magazine, bolt, or tank part can modify the game item.
Attachment advice also depends on the Call of Duty title, playlist, and balance patch. A setup that appeared in a Warzone 2 guide in 2023 may not have the same damage, recoil, movement, or unlock behavior in a later release. Treat every recommendation in this article as a configuration example rather than a permanent “best in slot” answer.
#1 Best Overall

The sources available for this topic are a third-party Warzone Loadout page, a 2023 Pro Game Guides article, and a fan-maintained Call of Duty Wiki entry. None supplies controlled testing or current official patch documentation. Where a source reports a trade-off, that trade-off is described as guidance—not as a measured performance result.
Three useful starting configurations
| Configuration | Attachments or change | What the source establishes | What remains unverified |
|---|---|---|---|
| Warzone Loadout example | Gunner D20 barrel; 12 Shell Mag; Verdant Hook Cylindrical laser; 12 Gauge Dragon’s Breath ammunition; Dashbolt 60 bolt | A Warzone Loadout page lists this five-part combination for the KV Broadside. | No controlled comparison, official endorsement, current patch status, or measured improvement is provided. |
| Historical Warzone 2 setup | ZLR Sport-8 barrel; Point-G3P 04 laser; Stockless modification; Dashbolt 60 bolt; 12-round magazine | Pro Game Guides recommended this combination in a 2023 Warzone 2 article. | Its present-day availability, statistics, and meta relevance are not established. |
| JAK Jawbreaker conversion | Conversion kit that changes the weapon to fully automatic fire and .458 SOCOM caliber, according to a fan reference | The Call of Duty Wiki entry says ammunition, barrel, magazine, and bolt modifications are blocked after conversion. | The fan page is not official current documentation; verify the behavior and unlock requirements in-game. |
These are starting points for different goals, not three versions of a proven universal build. The first two retain shotgun behavior; the conversion kit changes the weapon’s firing system and caliber, so it should be evaluated as a different weapon concept.
How to choose attachments by playstyle
For a conventional shotgun setup
Start with the Warzone Loadout combination if you want to reproduce a complete, contemporary-looking example from a loadout page: Gunner D20, 12 Shell Mag, Verdant Hook Cylindrical, 12 Gauge Dragon’s Breath, and Dashbolt 60. The page does not provide a controlled test showing that each part is optimal, so use the setup as a baseline and inspect the in-game stat panel before committing.
The historical configuration offers a second baseline: ZLR Sport-8, Point-G3P 04, Stockless, Dashbolt 60, and a 12-round magazine. The inclusion of a laser and Stockless modification indicates a setup built around handling choices, but the source does not provide enough test data to quantify hip-fire spread, sprint-to-fire time, or movement speed. Test those properties yourself in the current game rather than assuming the 2023 result still applies.
For capacity over mobility
The 2023 Pro Game Guides article describes a 25-shell drum as providing more capacity while imposing a mobility and handling cost. That is a clear decision axis: a larger reserve can reduce reload frequency, but the source does not establish the exact movement or handling penalty, nor whether the drum remains available after later updates.
If your current Gunsmith offers the drum, compare it directly with a 12-round or 12 Shell Mag option in the stat display and a private firing test. Use the smaller magazine when the drum’s handling penalty interferes with the way you enter fights; use the drum only when the additional shells solve a real reload problem.

For close-range responsiveness
A laser and a lighter or Stockless configuration are the relevant choices in the examples. The Point-G3P 04 laser appears in the historical build, while the Verdant Hook Cylindrical laser appears in the Warzone Loadout example. The available sources do not state that one laser is categorically better, so compare their displayed hip-fire and handling effects on your platform.

Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteDo not remove a barrel or bolt solely because a build is described as “fast.” The sources name the Gunner D20, ZLR Sport-8, and Dashbolt 60, but do not give numerical values for range, cycling speed, recoil, or spread. Keep the parts that support your engagement distance, then verify the resulting stats.
For aimed fire or greater reach
The two example builds both include a barrel, which makes barrel choice a sensible place to begin when you want to change the weapon’s reach or behavior. However, neither source supplies a verified range table or pellet-damage test. A barrel’s name alone is not evidence of a specific number of extra meters or a guaranteed damage breakpoint.
In practice, compare the unloaded and equipped stat panels, then fire the same target from several distances. Record whether the number of shots, hit consistency, or recovery time changes. This is a personal test under your patch, not a universal benchmark.
Attachment-by-attachment reading of the example builds
Gunner D20 and ZLR Sport-8 barrels
Gunner D20 is the barrel named by the Warzone Loadout example; ZLR Sport-8 is the barrel named by the 2023 Pro Game Guides setup. The evidence establishes that they were selected in those guides, not that one is objectively superior. Check whether your current game shows different movement, spread, range, or recoil values for each, and choose according to the distances you actually play.

The Warzone Loadout page lists a 12 Shell Mag, while the historical build lists a 12-round magazine. The Pro Game Guides article separately discusses a 25-shell drum and explicitly frames it as a capacity-versus-mobility-and-handling trade-off. Names and slot behavior can change between games or updates, so do not assume these items are interchangeable merely because they hold a similar number of shells.

Verdant Hook Cylindrical and Point-G3P 04 lasers
These are the two laser names present in the supplied builds. No source-backed comparison establishes which has tighter hip-fire, faster readiness, or a smaller penalty. Equip one at a time, read the exact stat changes shown by your game, and test both hip-fire and aimed fire before selecting.
12 Gauge Dragon’s Breath ammunition
Dragon’s Breath appears in the Warzone Loadout example as the ammunition choice. The available material does not provide current damage values, range limits, or a comparison against standard ammunition. Verify that the ammunition is unlocked and legal in your playlist, then assess whether its behavior fits your intended range rather than treating the name as a guarantee of superior damage.
Dashbolt 60 bolt
Dashbolt 60 is present in both listed conventional builds. That repeated selection makes it a useful common test point, but repetition across two third-party guides is not proof of a universal best choice. Confirm what the bolt changes in your current build and whether the slot remains compatible with your selected conversion or ammunition.

Stockless modification
Stockless appears only in the 2023 historical configuration. Because the source does not quantify its handling cost or benefit, treat it as a preference option for players willing to trade stability or other stock effects for a different movement profile. Compare it against the default stock in the same test conditions.
What the JAK Jawbreaker changes
The fan-maintained Call of Duty Wiki describes the JAK Jawbreaker as a conversion that locks the KV Broadside into fully automatic fire and changes its caliber to .458 SOCOM. It also says the conversion blocks modification of the ammunition, barrel, magazine, and bolt. If those restrictions are active in your version, the kit is not simply another attachment added to the conventional shotgun builds; it replaces key parts of their configuration logic.
Because this information comes from a fan reference rather than official current documentation, confirm every detail in the live Gunsmith. Look for the conversion’s firing-mode description, displayed caliber, newly unavailable slots, and any compatibility warnings. Do not infer current unlock requirements from an old video or a different Call of Duty title.

When the conversion is worth testing
- Choose it when you specifically want fully automatic operation rather than semi-automatic shotgun cadence.
- Expect to rebuild your decision around the slots that remain available; a conventional barrel, ammunition, magazine, or bolt plan may no longer be possible.
- Compare the converted weapon with the unconverted KV Broadside at the same distances and against the same target types.
- Remove the kit if its new recoil, ammunition behavior, or handling prevents reliable hits at your normal engagement distance.
A practical in-game testing procedure
- Record your context. Note the game title, playlist, platform, and patch shown by your installation. This prevents a 2023 Warzone 2 recommendation from being mistaken for a current universal setting.
- Build a baseline. Equip the KV Broadside without changing every slot at once. Capture the displayed damage, range, accuracy, recoil, mobility, and handling values available in your Gunsmith.
- Change one slot. Test the barrel, magazine, laser, ammunition, or bolt individually so you can identify what actually changes. Avoid attributing the combined result to the wrong part.
- Use repeatable distances. Fire at the same target from close, medium, and longer shotgun ranges. Record shots required, hit consistency, and time to recover for the next shot.
- Test both fire styles. Compare hip-fire and aimed fire if the attachment description affects either. A build that feels quick while sprinting may still perform poorly when you aim.
- Check reload and movement. With a 12-round option and any available drum, observe reload interruption, sprinting, turning, and weapon-ready behavior. The historical source specifically warns of mobility and handling costs for the 25-shell drum.
- Test the conversion separately. If you equip JAK Jawbreaker, repeat the baseline checks after confirming that the weapon is fully automatic and that the blocked slots cannot be edited.
- Save only after verification. Keep a conventional and a conversion preset if your game permits it. That makes it easy to return to the unconverted behavior after a patch or mode change.
Common mistakes and how to avoid them
Treating the title as a tank guide
No evidence supplied for this topic describes a KV Broadside heavy tank. Searching for armor plates, engine parts, or physical tank modifications will lead to a different subject. Use the Call of Duty weapon interpretation unless your publisher confirms another game or product.
The Tool Desk

The Warzone Loadout and Pro Game Guides pages provide example combinations, not official rankings or controlled tests. Presenting either as proven best-in-slot would overstate the evidence. Use the tables and tests above to adapt them to your mode and patch.
Carrying 2023 advice into a current patch unchanged
The Pro Game Guides configuration dates to 2023. Attachment unlocks, balance values, and even available slots can change. Recheck the current Gunsmith and patch notes available in your game before spending time mastering an old setup.
Assuming the JAK Jawbreaker preserves shotgun customization
The fan reference says the conversion blocks ammunition, barrel, magazine, and bolt modification. Confirm those restrictions before planning a conventional build around the kit.
Buying physical parts for an in-game problem
The attachments and conversion discussed here exist inside the game. No physical tank accessory, miniature conversion part, firearm component, or other product is evidenced as a direct way to apply these changes to the digital KV Broadside.
Which setup should you try first?
For a straightforward conventional baseline, start with the five parts listed by Warzone Loadout: Gunner D20, 12 Shell Mag, Verdant Hook Cylindrical, 12 Gauge Dragon’s Breath, and Dashbolt 60. If your priority is a lighter-feeling configuration, compare it with the 2023 Pro Game Guides combination of ZLR Sport-8, Point-G3P 04, Stockless, Dashbolt 60, and a 12-round magazine, while treating that recommendation as historical.
If you want a different firing model, test JAK Jawbreaker on its own and verify the reported fully automatic .458 SOCOM behavior and slot restrictions. The correct choice is the one that remains available in your game, matches your preferred hip-fire or aimed-fire approach, and performs reliably after you test it on your current patch—not the one with the strongest-sounding name.
