The KATT-AMR has quickly become one of Call of Duty: Modern Warfare 3's best sniper rifles. This slow-firing, bolt-action weapon can eliminate targets with a single bullet anywhere on the body. It's a fairly slow weapon, but if your aim is true, it's tough to find a sniper rifle better than this.

Warzone players will also want to fully level this weapon, as it's one of few sniper rifles that can instantly down a player with a single headshot. For those looking to become the best sniper possible, use these KATT-AMR builds to top the scoreboard in both core Multiplayer and Warzone.

Buffing the KATT-AMR's ADS speed and aiming stability is ideal for Multiplayer modes, so all of this build's attachments will focus on those two stats. The SZ 1mw PEQ laser and Tempus Aura Heavy Barrel buff this gun's aiming stability, making it sway significantly less while aiming.

For ADS speed, we use the Tactical Stock Pad to cut this weapon's ADS time by 7.5%. The Sonic Suppressor XL will keep you off enemy radar, and the Ephemeral Quickbolt will make the KATT-AMR rechamber significantly faster, making this a solid choice for aggressive sniper users.

Perks Vest Assassin Gloves Marksman Gloves Boots Covert Sneakers Gear EOD Equipment Secondary Preference Lethal Throwing Knife Tactical Stim

Snipers require the element of surprise to win most gunfights, so a stealth build is a good fit here. The Assassin Vest gives you a version of the Ghost perk that's always active, even if you stand still. Covert Sneakers muffle your footstep audio, and Marksman Gloves minimize incoming flinch. Your choice of gear perk is up to you; we recommend EOD.

The equipment you run with this build isn't important and is down to preference. Some good picks include Stims for healing and Throwing Knives for quick one-hit kills. Your secondary weapon should cover close-range duels. Any automatic weapon is ideal, notably the Renetti with its carbine conversion kit.

The KATT-AMR is one of a select few sniper rifles that can kill a fully-plated player with a single headshot, even without Explosive Rounds equipped. This makes the KATT-AMR an excellent pick for Warzone This particular build will focus on making the KATT-AMR more consistent by buffing its bullet velocity and ADS speed.

The Tactical Stock Pad gives a massive ADS reduction with no noticeable downside. For bullet velocity, we use .50 Cal Spire Point Rounds. These grant a whopping 34.5% bullet velocity buff in exchange for less bullet penetration. We then use the Sonic Suppressor XL and Zang-34 Barrel to further buff the gun's bullet velocity.

All three attachments drastically buff this gun's effective range and bullet velocity. Your bullets travel at 1,181 m/s, making this gun hitscan up to around 90 meters. For the last attachment, you can either use an optic or the SZ 1mw PEQ laser. If you don't mind the default scope, we recommend the laser since it buffs your aiming stability.

Perks Perk Slot 1 Double Time Perk Slot 2 Sleight of Hand OR Mountaineer Perk Slot 3 Cold-Blooded Perk Slot 4 Ghost OR High-Alert Equipment Secondary Any Assault Rifle or SMG Lethal Throwing Knife Tactical Stim

Since your KATT-AMR will cover all long-range fights, you'll want a second weapon that excels in close and mid-range fights. SMGs are ideal, but an assault rifle built for handling stats can also work. Run Throwing Knives to one-tap downed players, and use Stims to give yourself a speed boost when you need to reposition.

As for perks, many of these slots are down to preference. Double Time is a must since it greatly increases your tactical sprint duration and recharge speed. Sleight of Hand is good if your secondary weapon reloads slowly, but you can get away with Mountaineer if you're using an MW3 weapon that doesn't benefit from faster reloads.

For the third perk slot, you have a lot of great options. Quick Fix and Tempered are fan-favorites for most playstyles, but we're going to recommend Cold-Blooded for this setup so you don't trigger High-Alert while aiming at an enemy. For the final slot, use Ghost or High-Alert.
