Battlefield 6 devs disable Mk24's Underslung Mount days after Season 5 launch

What happened

Battlefield 6's Season 5 update, "Siege of Vegas," went live globally on Tue 13 Oct at 10pm AEST (Brisbane) / 11pm AEDT (Sydney, Melbourne), bringing two new maps and four new guns. Four new weapons arrived alongside them: the Z84M light machine gun, the RSPR submachine gun, the ELR-40 sniper rifle, and the MK24 assault rifle, each tuned to fit different roles across the new terrain.

Within a day of launch, the official Battlefield Comms account posted in the game's Discord that the Underslung Mount underbarrel attachment on the brand-new Mk24 had been temporarily disabled "while we resolve an unintended interaction," promising an update once it's safe to re-enable.

What changed

• Underslung Mount removed from the Mk24's loadout menu — you currently can't select it at all; the attachment slot defaults to other grips/foregrips instead.
• No ETA on a fix — devs say an update is coming once the bug is sorted, but gave no timeframe.
• Workaround: players wanting to tame the Mk24's recoil in the meantime need to use a standard grip instead of the underbarrel mount. The Underslung Mount currently can't be selected in the Mk24's loadout menu, and anyone wanting to keep running the rifle has to fall back on alternative underbarrel attachments like regular grips for things like recoil control.

The trigger was a nasty bug, not a balance nerf. The quick server-side lockout was due to a malfunction developers described as an "unintended interaction" — in practice a bug that massively disrupted the weapon's behaviour on the battlefield and led to unfair situations. Content creator DANNYonPC posted X footage of the glitch in action, with the well-known Battlefield creator capturing exactly how the error looks, demonstrating the weapon's completely broken behaviour in his video.

What players are saying

Reaction to this specific attachment fix has been low-key compared to Season 5 overall, which is drawing split opinions. Early reactions suggest players are divided over whether the update delivers on its promises, with some praising the chaotic firefights and visual presentation of Vegas Strip while others criticise its layout and the continued absence of requested features. Discussions across Reddit suggest that new content alone may not be enough to satisfy players who have spent months calling for improvements to the game's core mechanics.

The Mk24 glitch itself is being treated mostly as a "classic day-two bug" moment rather than a flashpoint — European Battlefield outlets picked up DANNYonPC's clip and noted the community's half-joking take that the patch felt rushed, with one post even quipping it looked like an "AI-generated" update.

What it means for you

If you've been grinding the new Mk24 since Season 5 dropped, don't panic — nothing's broken on your end, and there's no action needed beyond re-equipping a different underbarrel attachment until the fix lands. Australian/OCE servers aren't affected any differently than anywhere else; this was a global, server-side toggle, so matchmaking and ping on local servers are untouched.

Watch next

No date yet for when the Underslung Mount comes back — Battlefield Comms says it'll post again once the issue is resolved, so keep an eye on the official Discord and X account for the next hotfix note.

What to watch next: Battlefield Comms says an update will follow once the Mk24 bug is fixed, but no date has been given yet — watch the official Discord and X account.
