Call of Duty’s newest version, Modern Warfare 3, sees a variety of elements of older titles returning to the fold, along with new additions such as fun weapons like the AMR9.
The AMR9 attempts to fill multiple roles at once. An SMG with a moderate fire rate and an assault rifle-like frame, its major benefit comes in its effective range. Whether it be classic maps invoking nostalgia or the return of “run and gun” with slide canceling, many players are looking to make every weapon work.
The AMR9 is one of these guns that needs some serious help from the Gunsmith because, as a base weapon, it’s nothing to be excited about. Our build works on maintaining this range while boosting its mobility for your sprinting needs.
These are the best attachments for the AMR9 in MW3.

Our AMR9 SMG attachments for the MW3 build focus on a boost to damage, range, and recoil control to keep you in the fight at medium range and able to keep up with fast-fire rate SMGs up close as well.
Since releasing in season two, it’s become a top favorite in both multiplayer and Warzone, and with good reason. It’s a meta choice for any mode you play in CoD.
Best AMR9 build in MW3 multiplayer
- Optic: Slate Reflector
- Underbarrel: DR-6 Handstop
- Ammunition: 9mm High Grain Rounds
- Magazine: 50 Round Mag
- Rear Grip: Sakin ZX Grip
I’ve been using this AMR9 attachment setup after I’ve unlocked it, and while it certainly gets over the line in the midrange versus its SMG counterparts, it really loses out up close. I’ve found it to be a jack-of-all-trades, master of none. But after a recent buff shortly after launch, it’s more formidable than it started out.
What hurts this weapon are its poor iron sights, really forcing you to add an optic of choice. I found the bonus ADS from the Slate Reflector helped, but if you like the iron sights on the AMR9, perhaps lean in for a stock of your choice.
Make sure to use the 9mm High Grain Rounds for its buff to Bullet Velocity and Damage Range, and consider swapping out the 50 Round Mag for a barrel if you want more range. But I like this setup a lot.
Best AMR9 class in MW3 multiplayer
- Vest: Infantry Vest
- Handgun: WSP Stinger
- Tactical: Flash Grenade
- Lethal: Semtex
- Field Equipment: Comm Scrambler or Trophy System
- Gloves: Commando Gloves
- Boots: Tactical Pads
- Gear: Tac Mask or Ghost T/V Camo
This is our general setup for a run-and-gun style with an SMG, with a couple of flexible options. Commando Gloves and Tactical Pads with the Infantry Vest aim to keep your aim consistent while swiftly moving around the map.
Generally, I’d lean toward the Trophy System given the amount of grenade spam I encounter in MW3, but opt for a Comm Scrambler (which pairs very well with a Counter-UAV) for objective-based modes like Hardpoint or Domination.
Ultimately, the AMR9 feels like the odd one out among the SMGs in MW3. Perhaps with a little more variety, this weapon will find a niche, but between making a harder-hitting AR more mobile or boosting the range and accuracy of the Striker (UMP) SMG, it falls through the cracks a touch.
With the right attachments unlocked, this versatile system can swing in both short-range bursts and mid-range encounters with relative ease, making for a decent weapon for any map.
