Best SMGs in BF2042: A Buying Guide
The best SMG in Battlefield 2042 for most players is the PP-29, because its low recoil and 40-round standard magazine let you hold down the trigger through a full 1v1 without reloading. If you want the fastest raw time to kill inside 15 meters, the K30 is the pick. If you want one weapon that works in both close quarters and mid-range, the MP9 (with the right barrel and grip) is the most flexible. The table below compares the main 2042 SMGs on the numbers that actually decide fights.
Quick Comparison: The Main BF2042 SMGs
| Weapon | Best for | RPM | Standard mag | BTK (10 m, upper chest) | Practical range | Recoil profile |
|---|---|---|---|---|---|---|
| PP-29 | Best overall / aggressive | 700 | 40 | 6 | 0–25 m | Low vertical, mild horizontal |
| K30 | Fastest TTK up close | 1,200 (high-RPM bolt) | 30 | 5–6 | 0–12 m | High, climbs fast |
| MP9 | Best all-round / controlled | 900 | 30 | 6 | 0–30 m | Low, predictable |
| PBX-45 | Best mid-range SMG | 750 | 30 | 6 | 0–30 m | Low, tight spread |
| P90 | Best for sustained fights | 900 | 50 | 7 | 0–20 m | Low, wide horizontal |
| PP-2000 | Best budget/unlock pick | 800 | 40 | 7 | 0–18 m | Moderate |
| MP28 | Vault SMG, close-range | 800 | 32 | 6 | 0–20 m | Moderate vertical |
Two numbers drive everything else: bullets to kill (BTK) and rate of fire (RPM). Time to kill is just BTK divided by shots per second, so a 5-BTK weapon at 1,200 RPM beats a 6-BTK weapon at 700 RPM by a wide margin, but only inside the range where the damage model still gives you that BTK.

How Time to Kill Actually Works in 2042
Per the game’s official patch notes and in-game damage readouts, SMGs use a three-step damage model: a maximum damage value inside a close range band, a reduced value in a middle band, and a minimum value beyond that. Your BTK changes at each band boundary, which is why the “best SMG” answer depends on where you expect to fight.
Worked example using the K30: at roughly 1,200 RPM it fires 20 rounds per second. A 6-bullet kill at that rate takes about 0.25 seconds of trigger time, plus the game’s first-shot delay and your own reaction time. The PP-29 at 700 RPM fires about 11.7 rounds per second, so a 6-bullet kill takes about 0.51 seconds. That 0.26-second gap is the entire argument for the K30 in a 5-meter hallway fight, and the entire argument against it at 25 meters, where its recoil and spread will push several of those bullets past the target.
Ranked Picks
Best Overall: PP-29
The PP-29 is the SMG most players should default to. Its 40-round magazine is the largest in the class outside the P90, its recoil is low enough to stay on a moving target through the whole mag, and its damage model keeps a competitive BTK out to roughly 25 meters. The trade-off is a moderate 700 RPM: you will lose a pure reaction-time duel against a K30 user who lands their first shots, so you need to pre-aim corners and use your larger magazine to win extended fights instead of snap duels.
Who it suits: players who push objectives constantly and want a weapon that does not punish a slightly sloppy first burst. Main trade-off: lowest burst damage of the top tier.
Best for Fastest Close-Range Kills: K30
The K30 with the high-RPM bolt installed is the fastest-killing SMG inside 12 meters. Nothing else in the class matches its TTK there, and it is the standard pick for players who clear rooms for a living. The cost is steep: recoil climbs hard after the first five or six rounds, the 30-round magazine empties in about 1.5 seconds of continuous fire, and past 15 meters you are better off switching to your sidearm than continuing the burst.
Who it suits: players who control engagement distance and never take a K30 into open ground. Main trade-off: effectively unusable beyond 15 meters.
Best All-Round / Most Controllable: MP9
The MP9 sits between the PP-29 and K30 in rate of fire at around 900 RPM, with the lowest and most predictable recoil pattern in the class. Its practical range stretches to about 30 meters with the right barrel, which means you can hold a doorway and still contest a player across a courtyard. The trade-off is a 30-round magazine that runs dry quickly at 900 RPM, so you will reload more often than a PP-29 user.
Who it suits: players who want one SMG for every map and mode. Main trade-off: frequent reloads in extended fights.
Best for Mid-Range: PBX-45
The PBX-45 fires slower than the MP9 but has the tightest spread and lowest recoil of any SMG in the class, which makes it the only one that comfortably holds 30 meters without switching weapons. It behaves more like a compact assault rifle than a bullet hose. The trade-off is a slower TTK up close than the PP-29 or K30, so you lose the pure aggressive duels.
Who it suits: players who hold angles and cover instead of rushing. Main trade-off: you give up the close-range TTK advantage entirely.
Best for Sustained Firefights: P90
The P90’s 50-round magazine is the largest in the SMG class and lets you fight two or three opponents in sequence without a reload. Its recoil is low, though the horizontal spread is wider than the MP9’s, so it works best at 10 to 20 meters where you can track a target rather than snap to one. Its BTK is one bullet worse than the top tier, which shows up in pure 1v1 duels.
Who it suits: players who fight multiple enemies per engagement. Main trade-off: slower individual kill than the PP-29 or K30.
Best Budget / Early-Unlock Pick: PP-2000
The PP-2000 is available early and needs no exotic attachment unlocks to be usable. It carries a 40-round magazine and fires at around 800 RPM, giving it a forgiving damage model at short range. It is a genuine downgrade from the PP-29 in recoil control and BTK, but it is the correct choice if you are still unlocking attachments and do not want to spend your early playtime on a weapon that feels broken.
Who it suits: new players and anyone leveling before the top-tier SMGs open up. Main trade-off: worst recoil control of the 40-round options.
Attachment Choices: Aggressive vs. Controlled
Attachments in 2042 trade one stat for another. There is no build that maximizes everything, so pick the column that matches how you actually play.
| Slot | Aggressive build | Why | Controlled build | Why |
|---|---|---|---|---|
| Muzzle | Flash hider / no brake | Keeps you off the minimap; you are moving anyway | Compensator | Cuts the vertical climb that ruins mid-range bursts |
| Underbarrel | Laser sight | Tighter hip-fire spread for close pushes | Grip (vertical or angled) | Reduces horizontal drift during sustained fire |
| Optic | 1x reflex | Fastest target acquisition, no tunnel vision | 1.5x–2x | Lets you actually see targets at 25–30 m |
| Ammo | Extended mag | More kills per magazine in a rush | Standard or high-power | Accepts reload downtime, gains damage retention at range |
Aggressive Build Rules
- Take the extended magazine on any SMG with a 30-round base — the reload you avoid is worth more than the handling you lose.
- Skip magnified optics. Aggressive play happens inside 15 meters, where a 1x is strictly faster.
- Pair the K30 with a laser sight and accept that you are building a 12-meter weapon, then play only 12-meter fights.
Controlled Build Rules
- Compensator plus grip is the single biggest recoil reduction available; on the MP9 and PBX-45 it turns them into 30-meter weapons.
- Keep the standard magazine if you hold angles — you have time to reload behind cover, and the handling bonus helps you re-peek.
- Use the MP9 or PBX-45 as your base for this build; the K30’s recoil is too high for a compensator to fix.
Choosing by Situation
| Your situation | Pick | Reason |
|---|---|---|
| New player, few unlocks | PP-2000 | Forgiving, 40-round mag, no unlock dependency |
| Small map, constant CQC | K30 | Best TTK inside 12 m |
| Mixed maps, one loadout | MP9 | Controllable out to 30 m at 900 RPM |
| Defensive, holding lanes | PBX-45 | Lowest recoil and tightest spread |
| Facing multiple enemies | P90 | 50-round magazine |
| Want the safest all-round pick | PP-29 | 40 rounds, low recoil, competitive to 25 m |
Ownership Realities: What Actually Limits an SMG
The thing that wears out first on an SMG build is not the weapon — it is your magazine budget. At 900 RPM you empty a 30-round magazine in two seconds, and the reload animation is roughly 2.5 to 3 seconds depending on the weapon. That means a poorly timed reload costs you more fights than any attachment choice. The practical rule is: reload behind cover or not at all, and always take the extended magazine if your base capacity is 30.
The second limiting factor is range discipline. Every SMG in 2042 has a damage drop-off band, and firing past it does not just reduce damage — it also stretches your BTK, which stretches your TTK, which is exactly when a rifle or LMG kills you first. Learning each weapon’s practical range is worth more than any optic.
The most common mistakes are stacking a magnified optic and a long-range build on a weapon with a 12-meter damage band, and taking the K30 into open ground because it wins the stat sheet.
Frequently Asked Questions
What is the best SMG in Battlefield 2042 overall?
The PP-29 is the best overall SMG for most players because it combines a 40-round magazine with low recoil and a competitive bullets-to-kill out to roughly 25 meters. It does not win the fastest time-to-kill contests, but it is the most forgiving across the widest range of situations. The K30 is better if you only ever fight inside 12 meters.
Which BF2042 SMG has the fastest time to kill?
The K30 with its high-RPM bolt has the fastest time to kill of any SMG inside roughly 12 meters, because it fires at about 1,200 RPM while still killing in five or six bullets to the upper chest. Past that range its recoil and damage drop-off make it worse than the MP9 or PP-29. It is a specialist weapon, not a general-purpose one.
Is the P90 worth using in 2042?
Yes, if your problem is running dry mid-fight. The P90’s 50-round magazine is the largest in the SMG class, letting you engage two or three enemies without a reload. Its trade-off is a slightly worse bullets-to-kill than the top tier, so it is better for sustained fights than for pure 1v1 duels.
What is the best SMG for mid-range in BF2042?
The PBX-45 is the best mid-range SMG because it has the lowest recoil and tightest spread in the class, which keeps it accurate out to about 30 meters. Fitting it with a compensator and a grip extends that further. You give up close-range time to kill in exchange.
Which attachments should I use on an aggressive SMG build?
Extended magazine, a 1x reflex sight, a laser sight, and a flash hider with no muzzle brake. The extended magazine matters most because at 900 RPM or higher you will empty a 30-round mag in about two seconds. Skip magnified optics since aggressive fights happen inside 15 meters.
Is the PP-2000 good enough if I have not unlocked the top SMGs?
Yes. The PP-2000 carries a 40-round magazine at around 800 RPM and needs no rare attachments to function, so it is a usable weapon from the start. It has worse recoil control and a slower time to kill than the PP-29, but it will not cost you fights the way an unmodded 30-round SMG will.
