The Best AMR9 Loadout and Class Setup in MW3 Season 3

Table of Contents

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. If you’re wondering about the best AMR9 loadout in MW3, you’ve come to the right place.

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. This versatile weapon has quickly become a favorite among players looking for a balanced option in both multiplayer and Warzone. 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. The best AMR9 loadout in MW3 Warzone can differ slightly from the multiplayer setup, but the core principles remain the same.

• 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. The Slate Reflector provides a clear sight picture without obstructing your peripheral vision, which is crucial in fast-paced engagements.

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. The High Grain Rounds significantly improve the AMR9’s performance at medium ranges, making it more competitive against assault rifles.

The DR-6 Handstop is an excellent choice for the underbarrel attachment. It provides a noticeable improvement in recoil control without sacrificing too much mobility. This attachment is particularly useful when engaging targets at the outer edges of the AMR9’s effective range.

The 50 Round Mag is a personal preference. While it does slow down your reload speed slightly, the extra ammo capacity can be a lifesaver in extended gunfights or when facing multiple opponents. If you find yourself running out of ammo frequently, this attachment is a must-have.

Lastly, the Sakin ZX Grip enhances your overall control of the weapon. It improves both recoil control and aiming stability, making it easier to stay on target during sustained fire. This attachment is especially useful when trying to challenge assault rifle users at medium ranges.

• 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. This combination allows you to maintain accuracy while on the move, which is crucial for an SMG-focused playstyle.

The Infantry Vest is an excellent choice for SMG users as it provides increased tactical sprint duration. This allows you to cover ground quickly and get into advantageous positions before your opponents. The extra mobility can be the difference between winning and losing a gunfight.

For the secondary weapon, the WSP Stinger is a solid choice. It’s a reliable pistol that can bail you out in close-quarter situations when you run out of ammo in your primary weapon. Its fast draw time and decent damage make it a worthy sidearm.

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. The Trophy System can be a lifesaver when holding down objectives, while the Comm Scrambler can disrupt enemy communications and give your team a tactical advantage.

The Flash Grenade and Semtex combination provides you with both crowd control and lethal options. Flash Grenades can disorient enemies, making them easy targets, while Semtex can be used to flush out campers or deal damage to multiple enemies in tight spaces.

Commando Gloves are essential for an SMG-focused loadout. They allow you to reload while sprinting, which is crucial for maintaining momentum and pressure on your opponents. Tactical Pads complement this by allowing you to slide further, giving you more options for evasive maneuvers and aggressive pushes.

For the Gear slot, both Tac Mask and Ghost T/V Camo are viable options. Tac Mask provides resistance against tactical equipment, which can be crucial in objective game modes. Ghost T/V Camo, on the other hand, keeps you off enemy UAVs, allowing for more stealthy gameplay.

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. However, don’t let this deter you from giving it a try. With the right attachments and playstyle, the AMR9 can be a formidable weapon in the right hands.

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. The best AMR9 loadout in MW3 strikes a balance between close-quarter effectiveness and medium-range viability, allowing you to adapt to various combat scenarios. Remember, the key to success with the AMR9 is to play to its strengths. Use its mobility to your advantage in close quarters, but don’t be afraid to challenge assault rifle users at medium ranges. With practice and the right loadout, you might find that the AMR9 becomes your go-to weapon in Modern Warfare 3
