After the latest Battlefield 6 update, many players noticed that the 5mW Green Laser attachment stopped working on the DRS-IAR.
The attachment can still be equipped, but it remains permanently turned off in-game. Meanwhile, the 10-point Red Laser still functions normally, which makes the issue even more confusing.
This problem has already appeared across multiple reports and appears to be a weapon-specific laser activation bug introduced with the latest patch.
This full guide breaks down every working method to restore laser functionality on the DRS-IAR and other rifles using the same attachment system. You’ll find step-by-step fixes, testing instructions, and root cause explanations so you understand exactly why the 5mW laser stopped activating.
In Short (Quick Answers)
• The 5mW Green Laser on the DRS-IAR is broken due to a post-update attachment activation bug.
• The Red Laser still works because its activation logic was not affected.
• Resetting weapon configurations and clearing saved loadout data temporarily restores laser functionality for some players.
• The issue is on DICE’s side, but there are several reliable workarounds until an official hotfix arrives.
Why the 5mW Green Laser Stopped Working (And the Fastest Fix You Should Try First)
The latest patch changed how attachments load their visual states. The 5mW Green Laser’s activation script on the DRS-IAR fails to initialize when entering a match—meaning the laser never turns on even though the attachment is equipped. Switching attachments, swapping variants, or editing the loadout resets the configuration and often forces the laser to reload properly.
The fastest fix many players found is to remove the laser, switch to a different underbarrel/attachment, save the loadout, and re-equip the laser. This forces the game to regenerate the attachment’s activation state.
Quick Fix
Unequip the 5mW Laser → equip any other attachment → save the loadout → re-equip the 5mW Laser → restart the match. For many players, this immediately restores the laser beam.
Fix 1: Reset the Attachment Slot to Force a Fresh Activation State
Battlefield 6 laser problems often happen because the attachment slot loads corrupted state data after an update. The DRS-IAR is especially sensitive to these bugs because of its hybrid mounting rail logic. Resetting the slot forces the game to rebuild the attachment state and refresh the activation script.
These Battlefield 6 laser fixes work best when the laser is equippable but permanently off.
Steps
- Go to Weapons → DRS-IAR → Attachments.
- Unequip the 5mW Green Laser.
- Equip a different attachment in the same slot (e.g., Red Laser or Laser/Light combo).
- Save the loadout.
- Close the game’s menu fully and return to the main screen.
- Re-enter Attachments.
- Re-equip the 5mW Green Laser.
- Start a match and test the laser.
Testing Step:
Aim down sights or hip-fire. If the green laser is now visible and toggleable, the attachment slot was corrupted and is now fixed.
Root Cause:
The update created a failure in the DRS-IAR’s attachment initialization chain. Resetting the slot clears the corrupted config, allowing the laser script to activate.
Fix 2: Swap Weapon Variants to Refresh Laser Activation Logic
The laser activation system sometimes fails on a specific weapon variant. Switching variants forces Battlefield 6 to reload a fresh set of attachment parameters, which often fixes lasers stuck in the “off” state.
This fix works especially well when switching the laser on another gun works but not on the DRS-IAR.
Steps
- Go to the DRS-IAR weapon page.
- Switch to a different variant or blueprint if you have one.
- Equip the 5mW Laser on that variant.
- Load into a match and test.
- Switch back to your preferred variant.
- Re-equip the laser and test again.
Testing Step:
If the laser activates on the alternate variant but also works when switching back, the refresh corrected the activation logic.
Root Cause:
Variants store separate attachment data blocks. When the default variant becomes corrupted, switching forces Battlefield 6 to reload attachment metadata.
Fix 3: Rebuild Saved Loadout Configurations
When Battlefield updates reset or modify loadouts, attachment files can break—the game thinks the laser is equipped, but the “activation state” file is invalid. Rebuilding the loadout from scratch fixes the broken internal reference.
These Battlefield 6 attachment fixes help when multiple attachments feel inconsistent after the update.
Steps
- Create a new loadout slot on your soldier.
- Do not copy an existing one.
- Equip the DRS-IAR from scratch.
- Add your preferred optics, grips, and barrel attachments.
- Equip the 5mW Green Laser last.
- Save the loadout.
- Enter a match and test the laser.
Testing Step:
If the laser turns on using the fresh loadout, your previous loadout was corrupted by the patch.
Root Cause:
Patches often restructure attachment behavior. Old loadouts reference outdated data, causing lasers to load incorrectly until rebuilt.
Fix 4: Test the Laser in a Solo/Co-Op Match First
Laser activation bugs sometimes only affect online sessions due to server-side attachment checks. Testing in Solo mode loads a simplified offline version of attachment logic. If the laser works offline but not online, the bug is server-related.
This method helps diagnose whether the laser issue is local or server-driven.
Steps
- Open Solo/Co-Op mode.
- Spawn with the DRS-IAR equipped with the 5mW Green Laser.
- Aim down sights and hip-fire to check activation.
- Switch to an online match afterward.
Testing Step:
If the laser works in Solo mode but breaks online, the issue is tied to server versioning or online attachment validation.
Root Cause:
Different game modes load different weapon scripts. Solo mode loads local data, making it easier to confirm whether the issue is engine-side or server-side.
Fix 5: Toggle Weapon Edit Mode In-Match to Refresh the Laser Script
Some players discovered that editing the weapon mid-match using the in-game Plus Menu forces attachments to reload. This can instantly restore a stuck laser without restarting the game.
This trick works because the Plus Menu reloads attachment states dynamically.
Steps
- Load into any match.
- Hold the Plus Menu button to open the dynamic attachment selector.
- Switch from the 5mW Laser to another underbarrel/rail attachment.
- Switch back to the 5mW Laser.
- Close the Plus Menu.
- Aim or hip-fire to test the laser.
Testing Step:
If the laser appears after switching attachments mid-match, the issue was caused by a faulty attachment load during match initialization.
Root Cause:
The Plus Menu reloads attachment modules without restarting the game. When the initial load fails, this menu forces a reload of the correct script.
Fix 6: Restart Battlefield 6 to Clear Temporary Attachment Cache
Some Battlefield builds cache attachment states between sessions. When the update changed laser behavior, the cached activation states did not update properly. Restarting flushes this temporary cache.
Steps
- Close Battlefield 6 fully—not suspended.
- Wait 10 seconds.
- Reopen the game.
- Go to your DRS-IAR loadout.
- Confirm the 5mW Laser is still equipped.
- Enter a match and test.
Testing Step:
If the laser activates after a fresh restart, cached attachment data was the issue.
Root Cause:
Battlefield temporarily stores attachment activation states to speed up loading. The update invalidated these cached states.
Fix 7: Rebuild Game Database on Console (PS5/PS4)
On consoles, updates sometimes cause attachment logic to misbehave due to corrupted cached databases. A database rebuild recalculates asset references and often fixes attachment activation problems.
Steps (PS5)
- Turn off the PS5 completely.
- Hold the power button until you hear the second beep.
- Enter Safe Mode.
- Select Rebuild Database.
- Wait for the process to finish.
- Launch Battlefield 6 and re-test the laser.
Testing Step:
If the laser works after the database rebuild, there was asset corruption in the console’s cached data.
Root Cause:
System-level caching sometimes conflicts with Battlefield’s attachment data after major patches.
Fix 8: Reinstall the Game (Last Resort for Persistent Attachment Bugs)
If none of the above fixes restore the 5mW laser, the issue is likely tied to corrupted local files or incomplete patch data. Reinstalling ensures fresh weapon scripts and attachment modules.
Steps
- Uninstall Battlefield 6 completely.
- Restart your console or PC.
- Reinstall the game.
- Recreate your DRS-IAR loadout.
- Equip the 5mW laser.
- Test the laser in a match.
Testing Step:
If the laser works after reinstalling, your local installation had corrupted attachment files.
Root Cause:
Attachment modules sometimes fail to update correctly, causing permanent activation errors until fresh files are installed.
Final Thoughts
The 5mW Green Laser not working on the DRS-IAR after the latest Battlefield 6 update is a known attachment bug affecting many players. The issue is caused by broken activation scripts, corrupted loadout data, or incomplete attachment initialization. Fortunately, the fixes above help restore proper laser behavior and keep the DRS-IAR fully functional.
1. Why did the 5mW Green Laser stop working on the DRS-IAR after the latest update?
This is a post-patch attachment behavior bug introduced in the most recent update.
The update changed several weapon attachment states and accidentally broke the activation logic for the 5mW Green Laser on specific weapon families — including the DRS-IAR.
The laser can still be:
- Equipped
- Selected
- Saved in loadouts
…but it never activates in-game, regardless of firing mode or stance.
2. Is the 5mW laser broken only on the DRS-IAR or on other weapons too?
Early reports show the issue is mostly isolated to the DRS-IAR, but a few players have noticed inconsistent activation on similar support/LMG-style platforms.
However, the red 10-point laser works normally, confirming that the issue is not universal — it is specific to the 5mW model on this weapon category.
3. Does switching stances or ADS modes make the laser turn back on?
Normally, the 5mW laser should activate:
- During hip-fire
- While aiming (depending on mode)
- When toggling laser states with the gadget button
But due to this bug:
- The laser state is forced to OFF
- It does not respond to input
- It does not activate in any stance
- It visually stays off even though the attachment is equipped
So no stance or toggle currently fixes the issue.
4. Is there a temporary workaround to get the 5mW laser working?
Players have reported only one partial workaround:
Rebuild the weapon attachment setup
- Remove the 5mW laser
- Equip a different attachment (e.g., red laser or another underbarrel)
- Save the loadout
- Restart the game
- Re-equip the 5mW green laser
This can sometimes make the laser activate for a session, but most players say the bug returns after restarting the game or changing maps.
Currently, there is no stable workaround.
5. Is this a known bug, and when will it likely be fixed?
Yes. Multiple reports have appeared since the newest update went live, specifically mentioning:
- The DRS-IAR
- The 5mW Green Laser
- The laser being permanently off
Because it’s a weapon attachment behavior issue, it will likely be included in the next:
- Minor weapon tuning hotfix, or
- Patch addressing attachment/UI bugs
These types of issues are usually fixed within 1–2 patch cycles, since they affect gameplay visibility and weapon handling.
