Best MW3 KATT-AMR loadout attachments
- Laser: FSS OLE-V Laser
- Barrel: Perdition 24″ Short Barrel
- Stock: Tactical Stock Pad
- Underbarrel: Cornerstone Bipod
- Bolt: Ephemeral Quickbolt
To kick off the best MW3 KATT-AMR loadout, we picked the Perdition 24″ Short Barrel and FSS OLE-V Laser to improve the gun’s overall movement, including ADS, sprint to fire, and movement speeds. The Tactical Stock Pad will further boost the ADS speed.
Then, we went with the Ephemeral Quickbolt to enhance the rechambering speed, which prevents you from taking a lot of time to reload during fights alongside the Cornerstone Bipod Underbarrel granting you bipod mount and a slight ADS speed boost.

MW3’s KATT-AMR is a one-shot kill at nearly all distances.
Best MW3 KATT-AMR Perks & Equipment
- Vest: Infantry
- Gloves: Marksman
- Boots: Stalker
- Gear: Tac Mask
- Lethal: Breacher Drone
- Tactical: Flash Grenade
- Field Upgrade: Comm Scrambler
When it comes to Perks, we suggest equipping the Infantry Vest as it enhances your Tactical Sprint, allowing for quicker and more agile navigation throughout maps. Then, the Marksman Gloves will reduce idle sway and flinch while ADS, providing an additional layer of agility to your gameplay.
Stalker Boots will improve your strafe and ADS movement speed, which could be critical for the KATT-AMR that lacks a bit of mobility. Further, the Tac Mask offers protection against enemy flash, stun, and gas grenades.
Finally, the Breacher Drone can secure a quick kill if your aim is on point, and the Flash Grenade will blind and deafen enemies granting an advantage in placing your shots correctly. The Comm Scrambler will disable enemies’ communication with intel within its radius and prevent enemies’ killstreak activation.

Players can find the KATT-AMR Sniper Rifle during MW3’s campaign mission Oligarch.
