- Modern Warfare 4 launches with 8 assault rifles, but only a handful are worth your time in multiplayer.
- The M4 is the current meta king — forgiving recoil, fast fire rate, works at every range.
- Kastov 762 hits harder but needs more recoil control to get the most out of it.
- Han 86 and Hyeon Burst are slept-on picks that can absolutely compete in the right hands.
- Oden and Cronen Squall sit at the bottom — not useless, just outclassed by better options.
Modern Warfare 4 dropped with 33 weapons at launch, and assault rifles are still the backbone of most loadouts. Whether you’re grinding ranked, running objectives, or just trying to go positive in pubs — the AR you pick matters. Some rifles feel immediately strong right out of the box. Others need the right attachments or a very specific playstyle to even compete.
This guide ranks all 8 assault rifles in COD MW4 from best to worst, based on fire rate, time-to-kill, recoil pattern, and how well each one holds up across different map sizes. Let’s get into it.
All MW4 Assault Rifles Ranked
Here’s the quick tier breakdown before we go into detail:
- S Tier (Absolute Meta): M4, Kastov 762
- A Tier (Meta / Strong): Han 86, Hyeon Burst
- B Tier (Contender): Patriot XMR, Cronen Squall
- C Tier (Situational): Axion, Oden
Now let’s break each one down properly.
#1 – M4 (S Tier) – Best Assault Rifle in MW4
No surprise here. The M4 is the best assault rifle in Modern Warfare 4, and honestly, it’s not particularly close right now. It fires at 810 RPM with a 30-round mag, manageable recoil, and reliable damage across close, mid, and long range. You don’t need to be precise with it — the gun does the heavy lifting.
What makes it stand out from the other ARs isn’t just the fire rate. It’s how forgiving it is. You can push aggressively and still win gunfights because of the fast TTK. You can sit back on a lane and still compete. Most guns in the game make you pick one or the other. The M4 doesn’t.
Its Apex Attachment — the M4 Hurricane — converts it into a faster-firing 5.7x28mm variant. It blocks the Barrel and Magazine slots, but gives you an SMG-style secondary role on the same weapon level. Worth grinding if you want two playstyles from one gun.

#2 – Kastov 762 (S Tier) – Best High-Damage AR
The Kastov 762 is the second-best assault rifle in MW4 and the top pick for players who prefer a slower, harder-hitting playstyle. It fires at 600 RPM — slower than the M4 — but each bullet does more damage. At mid to long range, it absolutely shreds. The problem is recoil. It kicks noticeably more than the M4, so random hip-fire or quick snap shots are not this gun’s strong suit.
If you spend time learning the recoil pattern and building around recoil control attachments, the Kastov 762 actually has the highest damage ceiling among all ARs in the game. It’s a pick for players who are confident in their aim and prefer winning on range over raw fire rate.
Its Apex Attachment, the Kastov ARC, adds an experimental RF pulse disruption barrel — most useful in Ground War where vehicles and killstreaks are in play.

#3 – Han 86 (A Tier) – Best AR for New Players
The Han 86 is the first assault rifle you unlock in MW4 — available right at the start — and most players write it off as a starter gun and never come back. That’s a mistake. Once you get comfortable with the recoil, the Han 86 is genuinely solid. It has a 740 RPM fire rate, 30-round mag, and it feels more mobile than the M4 when you’re pushing or repositioning quickly.
It’s not as flashy as the Kastov or as dominant as the M4, but for a free-to-build, unlocked-immediately rifle, it punches well above its reputation. Players have found that a long barrel actually cleans up the iron sights too, which helps if you don’t want to use up your optic slot.
The Apex Attachment — Han X20 Skybreaker — fires airburst shells to flush enemies from cover. Niche, but useful on closed maps or when defenders dig in on Hardpoint.
#4 – Hyeon Burst (A Tier) – High-Risk, High-Reward
The Hyeon Burst is the only burst-fire assault rifle in MW4, and it’s a weapon that rewards accurate players while punishing everyone else. It fires 6.8mm bursts at 375 RPM. Land your first burst clean — you win fast. Miss that first burst — you’re probably losing the fight.
In the right hands, the Hyeon Burst is actually a problem. The damage per burst is high, and at mid range it can compete with any AR in the game. The issue is consistency. Burst rifles are always punishing in CoD because the TTK advantage only shows up when you land the bursts perfectly.
Its Apex Attachment — Hyeon Hyperburst — fires a fast three-round burst and then transitions into full auto. This completely changes the weapon’s identity and makes it far more flexible. If you’re willing to grind the weapon level for the Apex, the Hyeon Burst becomes a much stronger choice.

#5 – Patriot XMR (B Tier) – Long-Range Specialist
The Patriot XMR fires at 645 RPM with a 25-round magazine — the smallest base mag of any AR at launch. It hits hard at mid to long range, which puts it in a similar lane as the Kastov 762. The difference is that the Patriot XMR has even heavier recoil and smaller ammo reserves. You basically cannot skip recoil attachments on this gun.
When built correctly, it’s a solid option for long-sightline maps where you want AR range without running a sniper. On compact maps or objective modes though, the 25-round mag will get you killed. The Apex Attachment — Patriot XMR Volt — fires stun darts to clear rooms, which at least adds some close-range utility.
#6 – Cronen Squall (B Tier) – Late Unlock, Bullpup Feel
The Cronen Squall is a bullpup assault rifle that plays more like a full-auto marksman rifle. It fires at 673 RPM with a 20-round magazine — the smallest base mag in the AR class. It unlocks at Level 55, the final player level, which means you’ll be deep into the game before you even touch it.
Its handling and the way it shoots feel distinct from the other ARs. It’s accurate and can do real damage at range, but the 20 rounds will limit you in longer fights. The Apex Attachment — Cronen Maelstrom — fires a guided missile, which is genuinely one of the more unique Apex Attachments in the game. Placement here may shift as more players grind to unlock it and generate more data.
#7 – Axion (C Tier) – Suppressed Niche Build
The Axion fires subsonic .300 BLK rounds and hides enemy death skulls on kills, which gives it a built-in stealth advantage that most ARs don’t have. It fires at 705 RPM with a 30-round mag. On paper that sounds promising. In practice, it lost significant damage range in the beta balance pass, and it never fully recovered that mid-range punch.
If you want a suppressed, stealth-focused AR that keeps you off the minimap and hides kills, the Axion is your only option in this class. For most players though, the M4 with a suppressor achieves similar stealth without the damage drop-off. The Apex Attachment — Axion Clearcut — pushes it toward a hipfire-heavy build, which suits close-quarters only.
#8 – Oden (C Tier) – Powerful but Painful
The Oden fires 12.7x55mm rounds — the biggest caliber of any AR in MW4 — and each shot is genuinely brutal. The problem is the fire rate: 413 RPM with a 20-round magazine. That is slow. Painfully slow. In most CoD gunfights, you don’t get the time needed to let the Oden’s power shine before an opponent sprays you down with literally anything else.
Its best use case is actually through the Apex Attachment. The Oden Sentinel converts it into a semi-auto sniper configuration. In that role, it’s actually more consistent than trying to use it as a full-auto AR. If you want to run the Oden, build it around the Sentinel and treat it like a marksman rifle rather than a standard AR.
Which MW4 Assault Rifle Should You Use?
If you want to stay competitive in multiplayer right now, start with the M4. It unlocks at Level 14, covers every map type, and doesn’t ask much from you mechanically. Level it first, get the attachments, and you’ll be fine in almost any lobby.
If you’ve got the M4 sorted and want a second AR to grind, go for the Kastov 762 for ranged maps or the Han 86 for a more mobile feel. Both reward playtime and get stronger as your attachment pool fills out.
