Attachments in Battlefield 6 unlock at weapon level milestones. Leveling the wrong guns first delays your competitive loadout.
Level milestones
Each weapon has tiered unlocks — optics, underbarrel, ammo types, and ergo mods. Check the level 20 and 40 slots before committing grind time.
Per-class priorities
- Assault — recoil + mag size on primary AR.
- Engineer — launcher velocity and reload.
- Support — bipod and suppression options.
- Recon — scope velocity and flinch reduction.
Leveling strategy
Bot lobbies for general XP, then weapon packages for stubborn guns. Do not level every weapon — focus your main role first.
