The KATT-AMR in MW3 is incredibly powerful, but its power comes at a punishing price of a slow firing rate and ADS speed. But with a little commitment, the KATT-AMR will be an absolute force to be reckoned with and one with extreme spawn-trapping capabilities. This is our best KATT-AMR loadout for MW3.

Best KATT-AMR build in MW3

The aim of this loadout is to add as much speed to the KATT’s firing rate and aim down sights. These are the best attachments to improve overall speed, including movement and aim for the KATT-AMR:

  • Barrel: Perdition 24″ Short
  • Underbarrel: Cornerstone Bipod
  • Laser: FSS OLE-V Laser
  • Stock: Tactical Stock Pad
  • Bolt: Ephemeral Quick

While the KATT-AMR is slow to fire regardless of which attachments you use, these are the best attachments to improve this weapon’s overall speed, making it a viable option to use on most maps without having to camp.

The KATT-AMR is best used for long-range fighting. This sniper is not as adaptable in closer-range fights as other MW3 snipers like the KV Inhibitor, MCPR-300, or any marksman rifles. It does, however, have one-shot capabilities that push it above other rifles. You don’t need to worry about headshots with this sniper rifle.

Tip:

It’s worth noting that the KATT-AMR has to be unlocked before you can begin customizing it. Fortunately, all you have to do to unlock it is reach rank 4. Coincidentally, this is also the level that you have to be in order to unlock the Gunsmith.

Best class setup for KATT-AMR in MW3

The KATT-AMR needs a lot of work when it comes to speed and efficiency. These are added through the use of the perk system with Vest, Gloves, Boots, and Gear. We recommend this class setup for the KATT-AMR:

  • Vest: Infantry
  • Tactical: Stun Grenade
  • Lethal: Frag Grenade
  • Field Upgrade: Munitions Box
  • Glove: Quick-Grip Gloves
  • Boots: Lightweight Boots
  • Gear: Ghost T/V Camo

Unless you want to run an SMG, the Infantry Vest is an added survivability bonus. This allows you to easily reposition in a fight or move around the map after getting a kill. This is best used for unsilenced weapons where holding a building or having a height advantage is difficult due to enemies’ ego challenging and revenge-killing.

While your lethal and tactical equipment is swappable based on your preferences, the Frag and Stun Grenades help lure enemies out of buildings or corridors, allowing you to punish with the KATT-AMR. The Quick-Grip Gloves are essential for swapping weapons if you run out of sniper ammo or need to switch to a firearm to deal with any enemies overextending in the fight. The Lightweight Boots increase overall movability speed for repositioning and to gain height advantage.

Finally, the Ghost Camo is great for this class as you will need to reposition throughout the fight rather than hold a single spot during the entire match. This blocks UAV and Heartbeat Sensor detection, allowing you to move quickly and invisibly across the map as a flanker. This strategy is extremely important for snipers in MW3.

There you have it! Utilizing this KATT-AMR build is guaranteed to increase your success rate while in both casual and Ranked Play lobbies.
