The DMZ mode in Call of Duty: Modern Warfare 4 treats your loadout as a genuine asset. Bring a weapon into Hajin, die without extracting, and it's gone. That tension is exactly what makes the Gunsmith worth understanding before you drop in. There are 33 weapons spread across eight classes, most of them locked behind a scavenger hunt for Weapon Manuals, and the rules governing attachments and cash costs can catch new players off guard.

How does the Gunsmith work in MW4 DMZ?
The Gunsmith becomes available once you hit DMZ Player Level 10. Before that point, you're limited to whatever you scavenge on the ground in Hajin. Once unlocked, the Gunsmith lets you spend DMZ Cash to purchase weapons and configure them with attachments before each deployment.
A few rules govern every purchase:
- Each weapon supports a maximum of 5 attachments.
- Every attachment you add increases the DMZ Cash cost of that weapon.
- Attachment options unlock through weapon progression, which is shared between DMZ and Multiplayer, so time spent in either mode counts toward the same pool.
- If you die in Hajin and fail to recover your gear, any purchased weapon is permanently lost from that deployment.
- Owned blueprints from Prestige rewards or the Store can also be purchased through the Gunsmith, but they still cost DMZ Cash and are not free.
How do you find Weapon Manuals?
Most weapons in the Gunsmith start locked. To unlock them permanently, you need to find their corresponding Weapon Manual somewhere in Hajin and successfully extract with it. Manuals drop as randomized loot, meaning no fixed spawn guarantees a specific manual every run.
Military Containers and Crates offer the best odds for finding Weapon Manuals. The Air Base bunker is one of the more reliable locations worth clearing during a run if you're hunting for them. Once you extract with a manual, that weapon becomes permanently available to purchase in the Gunsmith on all future deployments.
Blueprints provide an alternative path. If you have a blueprint for a weapon you haven't manually unlocked, you can still purchase it through the Gunsmith without finding its manual first.
All Gunsmith weapons in MW4 DMZ
Three weapons require no Weapon Manual at all: the Han 86 (Assault Rifle), the PPHS-41 (SMG), and the Sang 9mm (Pistol). Every other weapon needs a manual before it appears as a purchasable option in the Gunsmith.

What's the fastest way to unlock all Gunsmith weapons?
The most efficient approach is to treat every deployment as a dual-purpose run: complete your primary objective while actively looting Military Containers and Crates for Weapon Manuals. Don't hold onto a manual hoping for a cleaner extraction later. The moment you find one, extraction becomes the priority.
For the three no-manual weapons, the Han 86, PPHS-41, and Sang 9mm are immediately available at Level 10. Start building weapon progression on these while hunting manuals for the rest of the roster. The Han 86 gives you a usable AR from the very first session without any groundwork required.
Blueprints are worth acquiring if you want access to specific weapons ahead of finding their manuals. Check your Prestige rewards and the Store for any blueprints tied to weapons you're targeting. For a full breakdown of how DMZ Operator Traits interact with your loadout choices, that's worth reading before you invest heavily in any one weapon type.

Attachment and cash cost breakdown
The DMZ Cash cost of any weapon scales with how many attachments you add. A bare weapon costs less than one with all 5 slots filled. Every attachment slot you fill adds to the purchase price you pay at the start of each deployment.
This creates a real decision point. A fully configured weapon performs better but costs more to replace if you die. A lighter build is cheaper to lose but may struggle against well-equipped rivals. Finding that balance is part of what makes the Gunsmith a meaningful system rather than just a gear menu.
For context on what you'll face in Hajin with those weapons, the DMZ boss locations and commanders guide covers every Commander and Lieutenant spawn so you can plan which weapon class fits each encounter. The full Call of Duty: Modern Warfare 4 strategy guides collection covers everything from DMZ story missions to FOB stations if you want to build out your knowledge of the mode beyond just the Gunsmith.
