Battlefield 6 Boosting patches that add guns are immediately exciting because they create new niches. California Resistance delivered two new functional weapons (DB-12 shotgun and M357 trait sidearm), a new underbarrel attachment, and tweaks to existing weapon behavior through aim and responsiveness updates. Here’s how those items stack up for altering the gunplay meta.

#1 — DB-12 Shotgun (Meta-Shifting Close Quarters Tool)
The DB-12 is the update’s trump card for close-range chaos. A dual-barrel pump design that fires from alternating tubes grants a unique rhythm: two hefty hits in quick succession if you can land them. Because it’s offered on the free path of the event pass, expect immediate saturation—shotguns will suddenly be a more common counter to aggressive rifle play in houses and service corridors. The DB-12’s access on the event pass means skilled players and newcomers alike will be swapping into it quickly, honing new shotgun strats across multiple servers. 

#2 — M357 Trait Sidearm (Niche But Useful)
Trait sidearms aren’t headline material but they’re the fine brushstrokes that let players optimize loadouts. The M357 offers an option for secondary lethality—useful for run-and-gun builds that want a reliable sidearm for finishing kills. Expect it on players who favor aggressive gadgetry and who pair fast primaries with a heavy-hitting backup. 

#3 — Underbarrel Attachment (Slim Handstop & Attachment Tuning)
Small attachments can unexpectedly alter weapon spread, recoil control, or sprint-to-fire timings. The new underbarrel attachment and some of the tuning changes reduce recoil bloom and improve handling for certain ARs and SMGs. These changes won’t rewrite the meta overnight, but they’ll make certain mid-tier weapons more competitive by smoothing their handling envelopes. 

#4 — Aim Assist Revert & Responsiveness
A host of aim-assist and responsiveness changes shipped alongside the weapons. That can change weapon strength in subtle ways—guns that once felt floaty will now have cleaner interactions at range, and aggressive close-range exchanges should feel snappy. This affects how well shotguns close the gap (favoring the DB-12) and how reliably ARs punish overextension. 

#5 — Vehicle/Environment Interplay
The Eastwood map introduces new geometry and destructible features that change sightlines and interior chokepoints. Weapons that dominated in sandboxes with long sightlines may see less value here; conversely, shotguns and SMGs will be more impactful in resort villas and clubhouse interiors. The environment always nudges the weapon meta—this time in favor of close-range tools. 

Conclusion: If you’re into the meta, the Battlefield 6 service DB-12 is the game’s most immediate lever. Pair it with the updated handling and the new map, and you’ve got a distinct shift toward interior domination that will animate nights of chaotic, satisfying gunfights.
