The KATT-AMR is a powerful sniper in Modern Warfare 3. Here is a detailed loadout guide for the weapon including setup, attachments, and perks.

Snipers are always a specialty in any Call of Duty game. These are high-risk and high-reward weapons where you can kill enemies in one shot (except semi-automatic snipers) but if you miss, then you are bound to fall.

Playing with a sniper requires skill, map knowledge, and patience, which means it will take work to get good at it. However, once you do, you will become the deadliest player in your lobby. The KATT-AMR is one such sniper rifle that allows you to dominate your games.

Here is a detailed guide for the KATT-AMR in Modern Warfare 3.


Best KATT-AMR MW3 loadout


  • Barrel: Perdition 24″ Short Barrel
  • Laser: FSE OLE-V Laser
  • Stock: Tactical Stock Pad
  • Rear Grip: Phantom Grip
  • Bolt: Ephemeral Quickbolt

The focus with any sniper in multiplayer is to maximize ADS speed and handling to help it keep up with 6v6’s fast-paced gameplay. One of the most impactful attachments for this is the FSE OLE-V Laser, just as it was in MW2.

Equally, the Perdition 24″ Short Barrel makes a substantial difference to ADS speed while also providing a nice bump to Movement speed and Sprint to Fire Speed. This comes at the cost of effective range but this is rarely a concern in multiplayer.

The Tactical Stock Pad is a must-have with it providing a sizable improvement to ADS speed with its only downside being recoil control. Given the KATT-AMR’s very slow fire rate, this downside is negligible. It’s a similar story with the Phantom Grip rear grip which is also well worth using.

Moving away from handling-focused attachments, the Ephemeral Quickbolt is excellent as it improves the KATT’s fire rate from 41 RPM to 57 RPM. That 38% boost is huge and makes this heavy-duty sniper much more forgiving.

Best KATT-AMR MW3 class: Perks & equipment

  • Vest: Gunner Vest
  • Gloves: Marksman Gloves
  • Gear: Bone Conduction Headset
  • Lethal: Semtex
  • Tactical: Flash Grenade

The Gunner Vest was practically made for the KATT-AMR. Not only does it let you use a second primary weapon like an SMG to cover the AMR’s obvious weaknesses, but it also improves reload speed which at 4.8 seconds is one of this sniper’s biggest downsides.

With this vest equipped you’ll only have access to the Gloves and Gear slots. For Gloves, we recommend the Marksman Gloves which reduce both idle sway and flinch during ADS, perks that lend themselves well to sniping.

Meanwhile, Gear is more debatable but we like the Bone Conduction Headset which makes enemy footsteps and gunshots much easier to locate. This can be a lifesaver when scoped in when your situational awareness would be otherwise reduced.

As for equipment, the Flash Grenade and Semtex still work as a classic combination that offers a great mix of utility for pushing players and a lethal final blow to finish off enemies.

How to unlock the KATT-AMR in Modern Warfare 3

The KATT-AMR sniper rifle can be unlocked in MW3 by reaching Level 4 when you first get access to the Gunsmith. Once you have the KATT, you’ll then need to work through 27 gun levels to unlock all its unique attachments.

Best KATT-AMR alternative in Modern Warfare 3

In terms of MW3 weapons the nearest competitor to the KATT-AMR is the KV Inhibitor which trades off raw power for better mobility and handling. However, a better alternative would be the MW2’s Victus XMR which is another hard-hitting .50 cal sniper rifle.

That’s all for our KATT-AMR loadout in Modern Warfare 3. For more MW3 coverage, check out these guides below:
