There are a lot of candidates for the best guns in Modern Warfare 3, because all of the weapons in Modern Warfare 2 have been carried forward, alongside plenty of new ones.
We’re solely focusing on the new weapons in Modern Warfare 3 here, because for the most part, anything that was a strong weapon last year will retain its power here, but the new guns are more of an unknown quantity.
So no matter your playstyle, if you’re wondering which guns to focus on leveling up first, we’ve tested all of the new introductions to determine the best guns in MW3.
Modern Warfare 3 best guns to use at launch
The best weapons in Modern Warfare 3 are as follows:
- MCW (assault rifle)
- AMR9 (SMG)
- SVA 545 (assault rifle)
- BAS-B (battle rifle)
- Katt-AMR (sniper rifle)
- Riveter (shotgun)
- Holger 554 (assault rifle)
As with the beta, we’ve placed the MCW as the best gun in Modern Warfare 3 because, for the most part, it’s your jack-of-all-trades gun. You can kit it out for long-range engagements — which our suggested attachments below are apt for — or to deal with enemies up close if needed.
However, if you want to primarily focus on close-quarters combat with the occasional ranged battle, opt for the AMR9 in second instead. The SVA 545 is also a great assault rifle, with the added bonus of firing its first two rounds almost simultaneously, but doesn’t quite have the recoil control the MCW offers. The BAS-B and Katt-AMR are even better at longer range, while the Riveter is the best shotgun and can decimate enemies up close. Finally, the Holger 556 is another solid assault rifle with the right attachments.
(As an aside, for those returning from the beta, the guns which have been removed from our list are the Striker, Longbow, MTZ Interceptor, and MTZ-556, which don’t quite hold up to the above at launch.)
Let’s go through our updated selections, one-by-one.
1. MCW (assault rifle)
Kicking things off is the MCW, which is unlocked at rank 44. Modern Warfare 3 doesn’t have real weapon names, so the MCW is best known as the ACR from previous installments. Which is all to day, the MCW is a very reliable assault rifle that is fully automatic, with consistent range, recoil, and damage.
Essentially, with the right attachments, the MCW becomes a laser beam. Any of the heavy barrels do the job — we’d recommend the 16.5” MCW Cyclone Long Barrel — along with any vertical grip, though we found the Bruen Pivot to be the best (which requires leveling the SVA 545 to level 12 first). As for the rest of the attachments, an optic is always a good shout for enhanced visibility, alongside any combination of muzzle/stock/rear grip that assist with recoil control and bullet velocity.

2. AMR9 (SMG)
Unlocked as the very final gun through standard progression at rank 55, the AMR9 is a direct competitor to the MCW, along with being the best SMG in the game. How, I hear you ask? Essentially, you can kit it out to be an absolute monster at range - seriously, it’s essentially an assault rifle with our best AMR9 loadout - or you can utilize it up close. The two essential attachments for the former are the Nimbus-6 Integrated Suppressor barrel and 9mm High Grain ammunition, both of which are unlocked at the final two levels of the gun, so it does take a while to get to.
Until that point, you can play around with utilizing the AMR9 however best you see fit. The L4R Flash Hider and TA Venom Stock are two solid replacements while you’re leveling it up, or you can replace everything and go for an up-close-and-personal build with ease.
3. SVA 545 (assault rifle)
The SVA 545 is the first assault rifle you’ll unlock in the game, so while you’re grinding for the MCW and AMR9, it’s the one you want to be using. As soon as you unlock create-a-class you can equip it, and it comes with one very interesting perk: the first shot fires two bullets, almost simultaneously. This isn’t just the first shot of the magazine though; if you tap fire, you can ensure every shot is a twofer. It’s not overpowered or anything, but it is a nifty trick if you can get the hang of it.
As is always the case with assault rifles, you’ll want to manage the recoil on this, so we recommend an underbarrel grip such as the VX Pineapple, a barrel attachment that can improve the range and damage, and other attachments that support recoil management. It’s one of the only guns in the game with decent iron sights though, so you don’t need to stick an optic on it.

4. BAS-B (battle rifle)
All the weapons in this list are fairly similar: fully automatic guns that are best at varying ranges. The BAS-B is no different. The first battle rifle on the list, this is the gun you want to switch to if our MCW build above still doesn’t have enough range for you. It doesn’t fire quite as quickly as the MCW, but each bullet packs way more of a punch, and once you have some recoil-managing attachments on there, you can put a longer-range optic on it such as one of the 2.5x options.
When you’re in the opening levels of using the BAS-B though, we have just a few recommended attachments. The Bruen Venom Long Barrel is a no-brainer thanks to the range it adds, and the 30-round mag — or the 45-round once you unlock it — ensures you can mow down multiple enemies without needing to reload. We’d also recommend the Ravage-20 Heavy Stock, which you unlock once the BAS-B has reached level seven.

5. Katt-AMR (sniper rifle)
The best new sniper rifle in MW3 is definitely the Katt-AMR, which packs one hell of a punch. This is a .50 caliber sniper, and much like the SVA 545, is unlocked at level four (as soon as you get access to create-a-class.) As always, there are two ways to build a sniper; towards quickscoping, or towards setting up shop and picking enemies off from a distance. We’d recommend the latter with the Katt-AMR because of how unwieldy it is.
You’ll want to change the optic you have on it to something that fits your zoom preference. We went for the Signal 50 8X, which offers three different magnification levels, but this is ultimately up to you. The Sonic Suppressor XL is highly recommended as it hides your shots from the radar and increases bullet velocity and range, and the High Grain ammunition increases velocity and range. Stick the Tempus Aura Heavy Long Barrel on too for additional recoil control and less idle sway.
6. Riveter (shotgun)
If you want to rock a shotgun, look no further than the Riveter. This is fully automatic, so while it doesn’t output quite as much damage as some others, it’s the best at clearing multiple enemies at once. This is an armory unlock, so you must activate the challenge, then complete daily challenges to get access to it from level 25 onwards.
Since you’ll likely be sprinting round, clearing as many enemies as possible up close, you want attachments to match that. Focus on improving the sprint to fire speed, hipfire spread, aim down sight speed, and recoil where possible. The FTAC Grimline Laser, Demo D50 Buffer Tube, and Phantom Grip are all great for this. We’d also recommend the SA Draven-20 Long Barrel for extra range, as there’s nothing worse than engaging in a fight with a shotgun but not having the range necessary.
7. Holger 556 (assault rifle)
Finally, we have the Holger 556 which is unlocked at level 37. Now, to be frank, there’s not a whole lot special about the Holger; it’s a reliable, fully automatic assault rifle that isn’t quite as good as the MCW or SVA 545. However, if you remember the G36C from Call of Duty 4: Modern Warfare, this is very reminiscent of that.
As always, you’ll want to focus on recoil management and damage output when kitting out the Holger. Find barrel, muzzle, and underbarrel attachments that assist with that, then stick your optic of choice on and you’ll be good to go. It has a higher base damage but slower fire rate than both the MCW and SVA, so bear that in mind when finding the best attachments.
