Battlefield RedSec introduces a revolutionary weapon upgrade system that separates it from traditional battle royales. Instead of constantly swapping weapons for higher rarities, Gunsmith Kits let you transform any gun into a powerhouse through strategic attachment choices. Since RedSec’s October 28, 2025 launch, these unassuming satchels have become the most sought-after loot in Fort Lyndon. Master this system, and you’ll dominate firefights from the first circle to the final showdown.

What Are Gunsmith Kits and Why They Matter
Gunsmith Kits are category-specific upgrade items that boost weapon performance by one rarity tier while adding powerful attachments. They appear as thin satchels with weapon badges on the front—easy to overlook but absolutely critical for competitive play.
Unlike most battle royales where you constantly swap weapons for better rarities, RedSec allows you to upgrade guns through these kits, boosting specific stats and applying various attachments. This means if you find a weapon you love early, you can keep it throughout the entire match by progressively upgrading it.
The system features six rarity tiers: gray (common), green (uncommon), blue (rare), purple (epic), gold (legendary), and red (advanced—only available through custom weapon drops). Each Gunsmith Kit application increases your weapon’s rarity by one level while letting you choose between two attachment packages.
For insights on maximizing your weapon loadouts in battle royales, understanding upgrade mechanics is essential for competitive advantage.
How to Find Gunsmith Kits in Fort Lyndon
Gunsmith Kits don’t have fixed spawn points and appear in random locations throughout Fort Lyndon. However, certain containers offer better odds:
Best Sources:
- Orange Weapon Crates: Highest probability for Gunsmith Kits
- Mission Rewards: Frequently awarded after completing objectives
- Standard Loot Containers: Lower chance but still viable
- Desks and Tables: Scattered throughout buildings
Pro tip: Prioritize looting buildings with multiple orange crates during early game. The time investment pays off when you’re running a fully kitted weapon by mid-game. Check out strategies for efficient looting in FPS games to maximize your scavenging efficiency.
Step-by-Step: Using Gunsmith Kits
Method 1: Direct Ground Interaction
When you find a Gunsmith Kit on the ground, you can use it immediately if you have the compatible weapon type equipped. Simply hold the interact button (E on PC, Square on PlayStation, X on Xbox) while standing near the kit and holding the matching weapon category.
This instant-use method is fastest during hot drops when you need immediate firepower advantages.
Method 2: Inventory Management
If you want to save kits for later or share with teammates, pick them up and store them in your inventory. When you have a usable kit in your backpack, a blue arrow icon appears in the bottom-left corner near your armor indicator.
To use from inventory:
- Open inventory (Tab on PC, Touchpad/View button on console)
- Select the weapon you want to upgrade
- Look for the three rising colored arrows indicating upgrade availability
- Confirm your choice to open the attachment selection menu
Method 3: Team Distribution
Gunsmith Kits can be dropped and shared with squadmates. This becomes strategically important when your teammates are using weapon categories different from yours. Coordinate kit distribution based on who’s carrying which weapon types for maximum team efficiency.
Understanding Attachment Choices
When using Gunsmith Kits, you’ll select one of two available attachments, and the weapon rarity increases when the attachment is applied. These choices typically fall into categories:
Common Upgrade Paths:
- Accuracy Package: Improved precision, range handling, recoil reduction
- Versatility Package: Flash hider, mobility boost, faster reload speed
- Capacity Package: Extended magazines, ammo efficiency
- Mobility Package: Faster ADS, improved handling, weapon swap speed
The attachments offered vary based on weapon rarity—common weapons receive basic scope attachments, whereas high-rarity weapons get better attachments that significantly enhance performance.
Critical Decision Point: Once you use an upgrade kit on a specific gun, you can’t remove it and transfer it to another. Make sure you’ve found a weapon you genuinely like before committing multiple kits to it.
Gunsmith Kit Types and Compatibility
Each kit works exclusively with its designated weapon category:
| Kit Type | Compatible Weapons |
|---|---|
| Assault Rifle Kit | All AR platforms (SOR-556, M16A3, etc.) |
| PDW Kit | SMGs only (UMG-40, MP9, etc.) |
| Marksman Kit | Designated Marksman Rifles |
| Shotgun Kit | All shotgun variants |
| MG Kit | Light Machine Guns (KTS100, etc.) |
| Sniper Kit | Bolt-action and semi-auto snipers |
Understanding compatibility prevents wasted inventory space. If you’re running an SMG build, prioritize collecting PDW Kits over Marksman Kits.
Strategic Tips for Gunsmith Kit Usage
Early Game Priority: Apply your first kit immediately to gain attachment advantages during initial firefights. Even a green-tier weapon with attachments outperforms higher-rarity weapons without them.
Mid Game Optimization: By this point, you should have 2-3 kits stocked. Focus on upgrading your primary weapon to purple/gold rarity while keeping backup kits for replacement weapons if needed.
Late Game Considerations: Custom weapon drops containing your personalized loadouts appear during matches and are the only way to achieve red rarity. Balance between upgrading current weapons and saving resources for potential custom drops.
Team Coordination: In squad play, designate roles—have one player focus on close-quarters combat with upgraded SMGs while another maintains long-range superiority with upgraded marksman rifles.

Common Mistakes to Avoid
Over-hoarding: Don’t carry excessive kits. Keep 2-3 maximum and drop extras for teammates. Inventory space is precious for armor plates, healing items, and ammunition.
Rushing Upgrades: Not all attachment choices are beneficial. Read the stat changes carefully—some “upgrades” might reduce mobility or handling in ways that don’t suit your playstyle.
Ignoring Weapon Synergy: Upgrade weapons that complement your class abilities. Support players benefit from LMG upgrades for sustained fire, while Recon players should prioritize sniper kit collection.
Forgetting the Visual Indicator: Many players miss the blue arrow notification telling them they can use a kit. Check your HUD regularly to avoid carrying unused upgrades.
FAQs
Q1: Can I use Gunsmith Kits on custom loadout weapons that I call in during matches?
No, custom weapons that arrive via personal weapon drops are already at red (advanced) rarity—the highest tier possible in Battlefield RedSec. These weapons come fully equipped with your pre-configured attachments from the loadout menu and cannot be further upgraded using Gunsmith Kits. Kits only work on ground loot weapons found throughout Fort Lyndon, progressing them through gray, green, blue, purple, and gold rarities. Custom drops represent the ceiling for weapon performance, making them extremely valuable late-game items worth fighting over.
Q2: If I upgrade a weapon to gold rarity but then find a better base weapon, should I start upgrading the new one from scratch?
This depends entirely on situation and available resources. A gold-rarity weapon with well-chosen attachments will almost always outperform a gray or green weapon, even if the base stats favor the newer gun. However, if you find an S-tier weapon (like the M2010 ESR sniper or UMG-40 SMG) in blue or purple rarity, and you have multiple kits available, switching might be worthwhile. Consider factors like ammunition availability, your playstyle preference, remaining kits in inventory, and the current circle phase. Early-to-mid game allows experimentation, but late game demands commitment to your primary weapon. Generally, it’s better to maximize one excellent weapon than spread upgrades across multiple mediocre ones.
