Battlefield 6 Season 4 weapons matter more than usual because the season changes where you fight. The Pacific Front brings Tsuru Reef, a brand new map, and the returning Wake Island, and both maps mix long beach sightlines, open water crossings, and tight resort interiors. That blend rewards high-velocity rifles and LMGs at range while keeping close-range guns relevant indoors and around landing zones. If you want one answer per class: run the EF88 or M16A4 as Assault, the CZ3A1 or SGX as Engineer, the DRS-IAR or KTS100 MK8 as Support, and the M2010 ESR or L115 as Recon. The rest of this guide explains why those picks win, and what to swap in when a map pushes you the other way.
Assault: EF88 and M16A4
The EF88 is the best all-round weapon in Season 4, and it is not particularly close. It pairs controllable recoil with strong damage at the mid ranges where most Pacific Front fights actually happen, and it stays accurate enough to challenge targets across a beach without falling apart up close. Build it for stability: a mid-range optic, an extended barrel for velocity, and a grip that keeps the recoil pattern vertical rather than drifting sideways.
The M16A4 is the backup for players who prefer burst discipline. Its three-round bursts reward trigger control and punish spam, which makes it excellent on Wake Island's longer approaches where you can pick targets off before they close in. If you find yourself losing close fights with the EF88, the M16A4 will not fix that; it is a range weapon, and you should pair it with a fast sidearm for interiors.
Engineer: CZ3A1 and SGX
Engineers live in two worlds in Season 4: repairing vehicles near the front and clearing buildings on foot. The CZ3A1 covers the first job better, with the range and control to hold a lane while your squad works a vehicle push. The SGX covers the second, with a fast time-to-kill and strong hip-fire that makes it the best SMG for room clearing and landing-zone fights.
Pick based on your squad's plan. Running with armor on Tsuru Reef's open ground? Take the CZ3A1 and keep your distance. Playing the objective inside resorts and bunkers? The SGX wins those fights before the enemy can react. Engineers also get class bonuses that favor SMG hip-fire, so the SGX scales better than its raw stats suggest.
Support: DRS-IAR and KTS100 MK8
Support is the strongest class in Season 4's meta, and the DRS-IAR is why. It plays like an assault rifle with LMG benefits: laser-like accuracy, low recoil, and the ability to hold a lane indefinitely. Its small magazine is the only real weakness, so build for reload speed and learn to reposition after each burst rather than holding the trigger down. On Breakthrough and Rush, where defenders need to lock down lanes, the DRS-IAR is the single most valuable gun in the game.
The KTS100 MK8 is the long-range alternative, and it is almost unfair at distance. Its four-shot kill range stretches past 70 meters with a thermal scope, which makes it perfect for Wake Island's beach defenses. It was strong enough to earn a specific nerf in the battle royale mode, but in standard multiplayer it remains a top pick. Support players also take no sprint speed penalty with LMGs, which is a bigger deal on the Pacific Front's large maps than it looks on paper.
Recon: M2010 ESR and L115
The M2010 ESR is still the best sniper rifle for most players. It balances power and mobility better than anything else in the class, with one-shot headshots and manageable bolt cycle times. On Tsuru Reef, where sightlines run long but cover is plentiful, the M2010 lets you reposition between shots instead of camping one angle until someone flanks you.
The L115 is the pick for dedicated long-range players who want maximum damage per shot and do not mind slower handling. It shines on Wake Island's open beaches, where targets cross long stretches of sand with nowhere to hide. Whichever you choose, pair it with a close-range secondary: Season 4's maps will force you into buildings eventually, and a sniper rifle alone will not save you there.
Battlefield 6 Season 4 weapons by map
Tsuru Reef favors versatility. Its mix of jungle paths, resort buildings, and open ground means no single range dominates, so the EF88, DRS-IAR, and M2010 ESR all have a home here. Wake Island favors range: long beaches and island crossings punish short-range builds, so lean toward the M16A4, KTS100 MK8, and L115, and keep an SMG in your back pocket for the bunkers.
One last piece of advice: level one or two weapons at a time rather than spreading experience across the whole arsenal. Season 4's attachment system rewards specialization, and a fully kitted EF88 will do more for you than five half-built guns.
