Finding the best Sniper loadouts in Modern Warfare 3 Season 2 is essential for anyone who loves the marksman playstyle and insta-killing foes with a single well-aimed shot.

While SMGs and assault rifles are more forgiving in the majority of engagements, a Sniper in the hands of a talented sharpshooter feels impossible to counter as you're enemies are dead before they can even react.

Whether you're an OG quick-scoping fan or someone who prefers holding down power positions and picking off foes from afar in the game, there's a deadly set-up for you.

So, let's break down the best meta Sniper loadouts in MW3, so all of your rifles are optimized to be as strong as possible in multiplayer.

Best Modern Warfare 3 Sniper Rifles, ranked

5. SP-X 80

Best SP-X 80 loadout

  • Barrel: 18.5" Bryson LR Factory
  • Laser: FSS OLE-V Laser
  • Rear Grip: Schlager Match Grip
  • Stock: PVZ-890 Tac Stock
  • Optic: Forge Tac Delta 4

Bringing over its power from MW2, the SP-X 80 is back and it's still a quick scope machine. With a fast ADS time, plenty of mobility, and surprising consistency when it comes to insta-killing foes from afar, this gun is still a deadly choice.

The loadout above focuses on making the weapon as snappy and quick as possible, meaning if a foe comes around a corner, you'll be quicker on the draw.

It has unfortunately had its ADS speed nerfed in Season 2 though, which is why its dropped down this list. While 5% isn't a huge amount, with Snipers it can make all of the difference, as you need as much time as you can get to line up that all-important shot.

Best KATT-AMR loadout

  • Muzzle: Sonic Suppressor XL
  • Barrel: Perdition 24" Short Barrel
  • Optic: SP-X 80 6.6x
  • Stock: Tactical Stock Pad
  • Rear Grip: Phantom Grip

Bulky, slow, and hard-hitting, the KATT-AMR is a .50 Cal bolt-action Sniper that packs a punch from long-range in Modern Warfare 3. While damage output will never be an issue for this weapon, mobility is definitely a weakness and can result in the gun feeling sluggish.

The KATT-AMR is not an aggressive quick-scoping rifle, it's instead best suited when posted up in a power position and is devastating from extremely long distances.

It's because of this that the weapon sits at number five and will likely never contest the top spots in the rankings. However, it certainly has its place for a specific type of player.

3. KV Inhibitor

Best KV Inhibitor loadout

  • Muzzle: Shadowstrike Suppressor L
  • Barrel: Kastovia JEK-40 Barrel
  • Stock: Heavy Support Stock
  • Laser: FSS OLE-V Laser
  • Underbarrel: SL Skeletal Vertical Grip

The KV Inhibitor is a semi-automatic Sniper that's extremely easy to use thanks to its low recoil and minimal kickback. All this comes together to create an incredibly consistent rifle that may not be top-tier in the damage department, but will always deliver in mid-range skirmishes.

Long-range hit markers may cause some frustration, but if you're a player who wants a great starter weapon to jump into the world of sniping, the KV Inhibitor is a great choice.

Best XRK Stalker loadout

  • Barrel: KLX-09 Short Barrel
  • Laser: Schlager PEQ Box IV
  • Ammunition: .50 Cal Explosive
  • Stock: Helix LV Light Stock
  • Bolt: XRK Stalker Light Bolt

The XRK Stalker has risen to the upper echelons when it comes to Sniper Rifles in MW3 following its arrival in Season 1, as it brings the sheer power of .50 cal rounds that will never let you down in a gunfight.

While mobility isn't its biggest strength, the weapon can be built for the fast pace of multiplayer with a speedy ADS time and solid movement. This paired with the gun's deadly damage and you've got an extremely potent sniper.

It is currently the most popular Sniper in the game according to WZRanked, boasting a pick rate of 5.01% which is almost double of the next option. It simply just feels great to use alongside being a super reliable choice, which is exactly what you're looking for when hunting those one-hit highlights.

1. Longbow

Best Longbow loadout

  • Barrel: Pro-99 Long Barrel
  • Stock: No Stock
  • Magazine: 10 Round Mag
  • Laser: SL Razorhawk Laser Light
  • Rear Grip: Nought-Z3 Grip

Sitting comfortably at the top of our list, the Longbow is a powerhouse in nearly every department. The gun can be built for raw damage output, or designed to excel at quick-scoping, and that's exactly what we've done above.

Reducing the magazine count from its massive default 30 rounds to 10 will give you a snappy ADS time. Not only that, with some adjustments to the Stock and Rear Grip attachments, you can equip the Longbow with impressive mobility.

It's even had a buff to its aim down sight time, taking it down by 5% from 550ms to 520ms, which makes the gun feel even better to use and truly separates it from the rest. I always feel confident bringing the Longbow into any match, as it truly excels within pretty much any scenario.

So, if you want to relive your classic quick-scoping days from MW2 (2009) in our opinion, the Longbow should be your choice.
