Ever built a weapon in MW4 DMZ only to find that its final price is higher than expected? The base gun is only part of the cost. You also need to pay for attachments and their slots, while the Gunsmith discount can affect the final checkout total.
To make your DMZ Cash go further, unlock the discount, account for slot fees, and check the complete build price before purchasing.
How to Unlock the Gunsmith Discount
The Gunsmith unlocks at DMZ Level 10. The 5% Gunsmith discount becomes available at DMZ Level 25 through the DMZ progression system.
DMZ Level is separate from your general Player Level and an individual weapon's level. Make sure you unlock the correct progression reward rather than relying on the level displayed elsewhere.
Once the discount is active, check the Gunsmith checkout screen before purchasing. The final price is what matters when deciding whether a build fits your budget.
Why Does a $5,900 Weapon Build Cost $5,700?
Consider this ISO Nightshade build:
| Component | Price |
|---|---|
| ISO Nightshade | $3,000 |
| Pulse-MW Laser | $1,900 |
| First attachment slot | $1,000 |
| Total before discount | $5,900 |
| Price shown at checkout | $5,700 |
The checkout price is $200 lower than the sum of the three listed costs. That reduction equals 5% of the $4,000 combined weapon and slot costs, although this example doesn't confirm exactly how the discount is calculated.
When buying a weapon, use the final price shown at checkout rather than relying on your own calculation.
MW4 DMZ Weapon Prices
Your base weapon price determines how much cash remains for attachments. These selected level 1 Gunsmith catalog prices provide a starting point for comparing weapons.
| Weapon | Category | Catalog price |
|---|---|---|
| ISO Nightshade | SMG | $2,850 |
| VEL 46 | SMG | $2,850 |
| WZ.55 Striga | SMG | $2,850 |
| PPSH-41 | SMG | $2,850 |
| HAN 86 | Assault rifle | $4,750 |
| M4 | Assault rifle | $4,750 |
| Hyeon Burst | Assault rifle | $4,750 |
| Kastov 762 | Assault rifle | $4,750 |
These prices give you a starting point when comparing weapons, but your final cost also depends on the attachments and slot fees you choose. The ISO Nightshade is listed at $2,850 in the catalog, while the checkout example above shows a $3,000 base price. Check the price displayed in your own Gunsmith before purchasing, then review the final total after adding your attachments.
Why Attachment Slots Matter
In MW4 DMZ, attachment slot fees are separate from attachment prices. You must budget for both, and additional slots can increase the cost of a finished build.
Before buying, consider whether each attachment provides a meaningful benefit for your playstyle. Filling every available slot can make a weapon expensive without necessarily making it more effective for you.
How to Avoid Overspending on Gunsmith Builds
Use these checks before buying a weapon:
- ☐ Unlock the discount. Reach DMZ Level 25 and confirm the 5% upgrade is active.
- ☐ Compare base weapons. A less expensive weapon may leave more cash for the attachments you actually need.
- ☐ Include slot fees. Don't estimate the build by adding only the weapon and attachment prices.
- ☐ Choose useful upgrades. Prioritize attachments that suit your intended playstyle.
- ☐ Check the checkout total. Use the price displayed by the Gunsmith before confirming the purchase.
- ☐ Consider the risk of losing the weapon. An expensive build may not be worth risking while you're learning an area or testing a new setup.
The goal isn't necessarily to build the cheapest weapon. It's to get the performance you need without spending more DMZ Cash than you're comfortable losing.
