JAK 12 - Shotgun specs

JAK 12 at a glance

JAK 12 is one of the four weapons added in Modern Warfare 4 Season 1, which Activision dates to November 6, 2026. JAK 12 is a full-auto shotgun arriving in-season as an Event reward, and its weapon-level count is printed as [CLASSIFIED]. At 8 rounds with 16 in reserve it is the smallest capacity in the shotgun class, though that is a single-load figure rather than a rate of fire. Barrage adds a salvo of adhesive explosives that stick before detonating — a separate feature from the base pellet spread. It is not part of the 33 launch weapons that shipped on October 23, and this record is kept separate from that roster so the launch count stays accurate.

In-game description

Devastate close-ranged targets with this full-auto Shotgun that showers foes with a cluster of pellets. Its accuracy falls off quickly, and it kicks hard after each shot, so closing the distance is required. The JAK 12 excels as a breaching tool; if you anticipate enemies on the other side of that closed door, barge through and tear them to shreds.

The publisher’s description above explains the intended role of JAK 12. It should be read alongside its own numeric block: Not stated weapon levels, 8 base rounds, 16 reserve rounds and 323 RPM. These are published fields from the Season 1 announcement, not measurements made by this wiki. Terms like “best-in-class”, “heavy damage” or “highlights” describe intended use; they do not establish a damage table, a time-to-kill result or a tested advantage against a particular opponent. The configuration and mode still matter when interpreting such claims.

How it fits the class

Rezi 12 provides a launch-class reference: its launch block lists 6 rounds, 24 in reserve and 150 RPM. JAK 12 lists 8 rounds and 16 in reserve. Compare these base configurations before adding an Apex or a capacity attachment. A larger ammunition count describes ammunition available before replenishment; it does not establish more kills, a faster reload or better handling. The other class members are linked below so this comparison stays part of the complete roster.

Ammo and supply

The official Season 1 reserve for JAK 12 is 16 rounds, separate from the 8 loaded rounds. Reserve is ammunition outside the current magazine or feed, not a magazine attachment to add to its capacity. This entry does not infer a pickup amount, resupply interval or shared ammunition pool from a cartridge name. In DMZ, access and replenishment depend on the deployment and FOB systems; the announcement’s reserve field does not locate a specific ammunition cache or promise the same inventory after looting.

Magazine options

The Season 1 block supplies 8 base rounds for JAK 12. Its attachment categories are listed separately below, and the announcement does not enumerate every magazine capacity or reload duration. Do not add a chambered round to the published figure or import an extended magazine from an older game. Any Apex description that explicitly changes the feed or capacity describes a different configured weapon. Keep the original base count visible so a later build comparison can distinguish the source specification from the selected attachment setup.

Gunsmith attachment slots

The published categories for JAK 12 are Optic, Muzzle, Barrel, Underbarrel, Magazine, Rear Grip, Stock, Laser. Its Apex is JAK Barrage. Launch a salvo of adhesive explosives that stick to surfaces and targets before detonating with devastating results. Apex Attachments are equipped separately and do not consume an ordinary attachment slot, but the source may explicitly block individual categories for a conversion. Read those restrictions before planning a combination. Weapon progression unlocks shared attachments for compatible weapons, while Weapon Prestige relocks attachments on the weapon being Prestiged. The Gunsmith reference explains that progression context.

What is not measured yet

Season 1 has not launched, so no in-game verification of this weapon is possible yet. Damage per bullet, time to kill, recoil pattern and effective range are not published for it. The Season 1 announcement dates the season, and the weapon tuning page records the published balance pass for the launch weapons.

How to unlock it

Its availability criterion is Unlocked via Event. The Season 1 announcement does not name the specific event, and no Player Level requirement is published for it, so the unlock route cannot be narrowed beyond that. The Season 1 Battle Pass is 1,100 COD Points, or 2,400 for the bundle, and carries a catch-up system that grants 50+ rewards for players who fall behind. Create-a-Class opens at Player Level 4, and in DMZ an unlocked weapon can be bought from the FOB Gunsmith with DMZ Cash, looted during a deployment, constructed from a Weapon Manual found in Hajin, or bought from the FOB Vendor. A cosmetic Blueprint is a separate entitlement, rather than a replacement for the base acquisition route.
