Weapon upgrades separate winners from early eliminations in Battlefield Redsec. While most battle royale veterans instinctively swap weapons to climb rarity tiers, Redsec introduces a game-changing mechanic: Gunsmith Kits that transform your favorite weapons into powerhouse tools without constant swapping. These nifty items look incredibly unassuming—they’re just thin satchels with specific weapon badges slapped on the front, yet they’re among the most valuable loot on Fort Lyndon.

How to Upgrade Weapons in Battlefield Redsec
To use a Gunsmith Kit, players must first have the correct weapon equipped for that specific kit. There are several types of Gunsmith Kits, such as Assault Rifle Kits and PDW Kits, each designed for their respective weapon categories. The requirements are straightforward: PDW Kits work only on SMGs, MG Kits enhance LMGs, and so forth.
Step-by-Step Upgrade Process:
- Find a Gunsmith Kit – Gunsmith Kits spawn randomly in Battlefield Redsec as ground loot or in loot caches, though orange chests have a high probability of spawning one
- Equip Compatible Weapon – Ensure your primary or secondary weapon matches the kit type
- Access the Kit – Hold the interact button (E on PC) on the kit or open your inventory (Tab key)
- Choose Your Path – Select between two attachments to apply to your weapon. The attachments offered differ depending on the rarity you’re upgrading, with common weapons offering basic scopes while higher-rarity weapons may provide increased accuracy or magazine capacity
- Apply Upgrade – Your weapon instantly gains the selected attachment and improved stats
If you’ve got one in your backpack that you can use, you’ll see a blue arrow icon in the bottom left corner near your armor indicator, making upgradeable weapons easy to identify.
Upgrade Path Strategies
The weapons in Battlefield Redsec have two upgrade paths. You can select sight attachments or others that can increase the overall stats of your weapon. These buffs can range from reduced recoil, improved handling, or increased damage range.
Accuracy Package: Prioritize this for long-range engagements, typically adding precision scopes and recoil reduction for sustained accuracy at distance.
Versatility Package: Choose this for adaptable loadouts, offering flash hiders, mobility boosts, and faster reload speeds that excel in close-to-medium combat scenarios.

Finding Gunsmith Kits Efficiently
Gunsmith Kits appear throughout Fort Lyndon, but knowing where to prioritize your search saves precious time during the firestorm closing in.
High-Probability Locations:
- Orange/Rare chests (highest spawn rate)
- Standard loot caches and containers
- Mission reward completions
- Desks and workbenches in POIs
They’re surprisingly common items in containers, on desks, or as mission rewards, so it’s much easier to find weapon kits than consistently scrounge for high-tier loot. This accessibility makes upgrading your preferred weapon more reliable than hoping to find purple or gold ground loot.
Critical Upgrade Considerations
Permanent Commitment Warning: Once you use an upgrade kit on a specific gun, you can’t remove it and transfer it to another, so try to at least find a weapon you like before choosing to upgrade it. Don’t waste valuable kits on temporary weapons you plan to replace.
Kit Type Matching: Always verify kit compatibility before use—attempting to apply an Assault Rifle Kit to an LMG simply won’t work.
Inventory Management: Store unused Gunsmith Kits in your backpack for later rather than using them immediately on suboptimal weapons just because you can.

Custom Weapon Drops: The Red Tier
The last and top-most weapon level is red, and it can only be acquired by looting custom weapon drops. These are delivered at random locations during a match in the Redsec battle royale. Custom drops allow you to equip your personally configured weapons from multiplayer, complete with your preferred attachments and customizations.
While Custom Weapon Drops are extremely rare compared to Gunsmith Kits, they represent the absolute peak of weapon performance. Monitor the map for drop indicators and contest them aggressively when your squad has positional advantage.
Optimal Upgrade Timing
Early Game (First Circle): Grab any S-tier weapon and hold upgrade kits until you secure your preferred loadout. Don’t waste upgrades on placeholder weapons.
Mid Game (Circles 2-3): Continue upgrading until you reach Advanced quality—only Custom Weapons outperform this tier. Prioritize upgrading your primary weapon first, then secondary.
Late Game (Final Circles): Focus on Custom Drops if available. Your upgraded weapons should already be blue or purple tier by this stage.

Class-Specific Upgrade Priority
Different classes benefit from specific weapon types and upgrade paths based on their signature abilities and tactical roles.
Assault: Prioritize Assault Rifle kits with versatility packages for aggressive mid-range pushes Support: Focus on LMG kits with extended magazines and recoil control for sustained fire Recon: Stack sniper rifle upgrades with long-range optics and damage range buffs Engineer: Enhance SMGs and PDWs with mobility and close-quarters attachments

Frequently Asked Questions
Can I Upgrade the Same Weapon Multiple Times?
Yes! Each Gunsmith Kit increases your weapon’s rarity by one tier, so you can continuously upgrade from gray to green, green to blue, and so on until reaching gold tier. However, each upgrade requires finding a new kit specific to that weapon type. You’ll need multiple Assault Rifle Kits to take an AR from common all the way to legendary. The upgrade paths compound, meaning your second and third upgrades build upon previous choices. Plan your upgrade route strategically rather than randomly applying kits as you find them for maximum effectiveness in later circles.
Should I Upgrade Weapons Immediately or Save Kits?
Save your Gunsmith Kits until you find a weapon worth investing in long-term, especially S-tier guns like the KORD 6P67, L110, or M2010 ESR. Upgrading a mediocre weapon wastes valuable kits you might need later for superior finds. The exception is early-game survival situations where upgrading your current weapon might mean the difference between winning or losing a crucial firefight. Once you’ve secured a top-tier weapon you plan to use through final circles, aggressively apply all compatible kits to maximize its potential before the endgame.
