Why Can’t I Equip a Medium Shield in ARC Raiders? Here’s Why
If you’re staring at your loadout and the medium shield just won’t equip, you’re not alone. Many players run into this and think something is broken. Usually, it’s not a bug. ARC Raiders has strict rules around gear, weight, and progression. When one rule blocks another, the game simply refuses to equip the item.
This guide explains how medium shields work, what’s stopping you, and how to fix it the right way.
How Shields Work in ARC Raiders?
Shields in ARC Raiders are part of the armor system. They add protection, but they also add weight and take up specific equipment slots. The game balances shields around survival, mobility, and risk. That’s why heavier shields come with more restrictions than light ones.
You equip shields from the loadout or inventory screen. They are not cosmetic items and they are not passive upgrades. Every shield must fit your current setup, or the game blocks it.
Main Reasons You Can’t Equip a Medium Shield

There isn’t just one reason this happens. Several rules can stop a medium shield from equipping, and the game does not always explain which one it is.
- Your carry weight is already too high
- Another armor piece is using the same slot
- Your backpack or rig does not support medium armor
- The medium shield is not unlocked yet
- Your character progression is too low
- Other equipped gear creates a loadout conflict
Weight and Carry Capacity Limits
ARC Raiders uses a weight system for everything you carry. Weapons, ammo, tools, armor, and shields all count toward your total. Medium shields weigh much more than light shields. If your loadout is already close to the limit, the game refuses to equip it.
This is why the shield may look available but won’t attach. Once you remove a weapon, tool, or heavy item, the medium shield often equips instantly.
Equipment Slot and Rig Restrictions
Medium shields require the correct armor slot and a compatible rig. If another armor item already occupies that slot, the shield cannot equip. Some rigs only support lighter armor types and block medium shields completely. The game does not auto-swap items here. You must manually remove the conflicting gear first.
Progression and Unlock Requirements
Not all medium shields are usable right away. Some require progression unlocks through gameplay. Players often see the item in inventory and assume it’s ready to use. Visibility does not mean permission.
Until the unlock requirement is met, the game treats the shield as restricted. That’s why it refuses to equip even when everything else looks correct.
How to Equip a Medium Shield Correctly?
If the shield won’t equip, go through this process slowly. Don’t rush it.
- Open your loadout or inventory screen
- Remove any armor already using the shield slot
- Check your total carry weight
- Unequip heavy weapons or tools if needed
- Verify the shield is unlocked in progression
- Confirm your rig supports medium armor
- Re-equip the medium shield
Most players fix the issue by reducing weight or changing rigs.
Is This a Bug or Intended Design?
In most cases, this is intended design. ARC Raiders enforces equipment rules strictly. The UI does not always explain why something fails, which makes it feel broken. Actual bugs with shields are rare. If the shield equips after changing weight, slots, or progression, the system is working as designed.
Tips to Avoid Shield Equip Issues
A few habits make shield management easier.
- Check carry weight before adding armor
- Match rigs with armor type
- Unlock gear before planning loadouts
- Avoid stacking heavy items
- Review slot usage carefully
- Adjust gear before raids, not during
Conclusion
In short, you can’t equip a medium shield in ARC Raiders because of rules around weight, slots, rigs, or progression. The game blocks the action instead of warning you clearly. Once you meet the requirements, the shield equips without trouble.
Experiment with your loadout and don’t assume something is broken right away. If this guide helped you, share it with other players and drop a comment about what blocked your shield.
