Extract a Weapon Manual for the gun you want to unlock repeat purchases at the DMZ Gunsmith. Finding and extracting the gun itself gives you that individual weapon, not permanent permission to buy replacements. Manual drops are random, so a useful loot route still cannot guarantee the M4 or any other specific manual.
Identify the manual and its unlock
Look for an item named Manual: [weapon name]. Its tooltip identifies the gun it unlocks; check that name before deciding who in your squad should carry it. The Type 73 example below explicitly says it unlocks the ability to purchase that weapon in the Gunsmith.
Once you extract the matching manual, you can buy that base weapon again whenever you can afford it. Permanent access does not mean free weapons: each new copy costs DMZ Cash, with further costs for your build. The official FOB guide separates that purchase permission from an extracted weapon you can customize as a single instance.
| What you bring back or own | What it gives you |
|---|---|
| A matching Weapon Manual | Repeat access to that base gun in the DMZ Gunsmith, with a cash cost for each purchase |
| A looted gun | That individual weapon; losing it does not unlock replacement purchases |
| An owned Weapon Blueprint | Access to that particular build, including its one-time free use and later discounted purchases |
| A 3D Printer Recipe | A crafting unlock for the printer, rather than permission to buy a base gun |
Weapon Levels and compatible attachment unlocks carry between Multiplayer and DMZ. That shared progression does not replace the manual requirement for buying a locked DMZ base weapon. A leveled M4 can therefore still be locked in Buy New Weapon.
Search containers rather than a fixed gun spawn
Build a route around several loot opportunities you can reach and survive. Weapon Lockers, military crates and safes are useful targets in compounds, police stations and military areas. Check ordinary containers along the way too: manuals have also been reported in duffels, medicine cabinets and toolboxes, so checking only weapon storage can miss a find.
| Search target | Practical approach | Main limitation |
|---|---|---|
| Military crates and Weapon Lockers | Search compounds, police stations and military buildings on your route | A weapon inside is not necessarily a manual |
| Safes and locked loot rooms | Bring a matching key and read its location description before deploying | Access to the room does not guarantee your chosen manual |
| Duffels, footlockers and medicine cabinets | Open these while searching buildings, rather than checking only gun cases | Reports of a manual in one do not establish a repeatable spawn |
| Irradiated Containers | Look in Chemical Storage, then prepare a separate reactor trip | Finding the container is itself random, and it needs processing |
Higher-threat locations add tougher enemies and a greater risk of losing the find. Do not turn a manual run into a fight you cannot finish just because a guide favors a Critical or Extreme area. A nearby locked room you already have the key for may be a more manageable choice than crossing the map under-equipped.
An optional Chang-san Air Base run
If Operation Iron Citadel is available, its starting area is a convenient way to reach Chang-san Air Base. Search the accessible buildings, including their bags, lockers and bathroom medicine cabinets, then reassess your equipment before going deeper. The screenshot shows the air base marked Critical; this is still a dangerous deployment, including for solo players.
Treat this as a repeatable search area, not a fixed manual reward. In this guide's air-base discussion, the creator describes several runs without reproducing other players' high manual counts. A dry run does not establish that the route was patched, and another player's successful run does not establish a drop rate.
For another route, an Irradiated Container can produce a manual after processing at Reactor 02. You must first find the container and handle the nuclear facility's radiation and enemies. Use the Irradiated Container guide for preparation, the cleansing machine and the trip out. Neither that route nor ordinary looting guarantees a particular gun's manual.
Protect the find and bring it home
- Use a backpack with a Secure Slot if available. This is optional protection, not an unlock requirement: a manual in an ordinary slot also counts when you successfully extract with it. The Basic Pack does not provide the same protection; inspect the actual backpack you are using.
- Move the manual into a Secure Slot as soon as you find it. Keeping it in an ordinary backpack slot leaves it exposed to loss if you fail to extract. The official backpack rules describe Secure Slots as protecting their contents when an exfil fails.
- If playing in a squad, give it to the player who needs that unlock. A squadmate extracting the manual does not award it to every teammate. The personal unlock is explained in this manual guide.
- Prioritize extraction once you have the manual you wanted. Extra buildings add exposure while carrying the item that was the purpose of the run.
- At the FOB, open Gunsmith → Buy New Weapon and inspect the matching base gun. Confirm the unlock before treating the run as complete.
A Secure Slot protects the item; putting something into one is not, by itself, proof that its permanent unlock has registered. The stated unlock condition is extracting with the matching manual. After a failed extraction, check your FOB inventory and the weapon's purchase state instead of assuming either success or loss.
Check a manual that appears not to work
Start by separating an expected inventory change from an actual missing unlock:
- The manual disappeared after a successful exfil: This can be normal. The official FOB guide says manuals are consumed at exfil, unlock their purchase option and pay 5,000 DMZ Cash. Check the gun rather than searching only for the paper item.
- You brought back the gun itself: That adds a weapon instance. It does not substitute for that gun's manual.
- The item named a different weapon: Inspect that weapon in Buy New Weapon. A manual is specific to its named gun.
- A teammate carried it out: Check who actually held the manual at extraction; the unlock is personal.
- The base gun is available but the build is not: Check your DMZ Cash, selected attachments and attachment unlocks. Purchase access and the cost of assembling a weapon are separate conditions.
- The matching base gun still shows locked after you extracted its manual: Record the weapon name, platform and what the post-match and Gunsmith screens show. Creator reports describe this problem, but they do not establish its cause or a reliable fix. In this report, the creator explicitly says the cause is unknown. If the manual remains in your FOB inventory, keep it there rather than risking it on an unverified re-extraction workaround.
If the Gunsmith station itself is unavailable, check its current DMZ progression requirement. A high Multiplayer Weapon Level and a manual in your inventory do not demonstrate that the FOB station is accessible.
