How Good is the JAK Cutthroat Aftermarket Part? - 7 Amazing Loadouts to Try in MW3

In-depth stats & review of the brand-new JAK Cutthroat Aftermarket Part, including 7 excellent, highly-tested builds to try it out on!

Modern Warfare 3 offers a plethora of attachments, many of which are virtually identical, making the gun customization process quite perplexing. Looking up class setups online can be clouded by tons of clickbait and low-effort junk. However, if you seek well-researched and performance-proven class setups from a genuine Call of Duty connoisseur, you've come to the right spot! This guide will delve into the optimal loadouts utilizing the JAK Cutthroat Stock in 6v6 maps.

Best JAK Cutthroat Weapon Builds

The JAK Cutthroat is an Aftermarket Part newly released in Week 3 of Season 3! This guide will review the way it works, its stats, which guns it works on, and seven excellent, highly-tested builds that make great use of it! The JAK Cutthroat Stock can be equipped to any weapon on the MCW, MTZ, M4, and AMR9 weapon platforms, which is essentially any weapon that uses those weapons as a frame, so to speak. It provides the absolute best possible improvement to Strafe Speed out of a singular attachment, on top of a nominal bonus to Movement Speed. However, it also significantly increases your recoil: a uniform 10% to Gun Kick, Vertical Recoil, and Horizontal Recoil. Many attachments cover the Vertical and Horizontal, but countering the Gun Kick without using a bulky compensator rests on a good Underbarrel selection. Let’s take a look at the stats:

My Great Game - My Great Capture_2024-04-19_19-52-28.png

In order to take advantage of that massive boost to Strafe Speed - allowing you to dodge opponent’s shots in real time - we’ll need to gear our weapons carefully to make sure we properly balance the drawbacks and craft beautifully performing weapons that are better than ever before! The full list of weapons the JAK Cutthroat can be equipped to are:

  • AR: MCW
  • AR: MTZ-556
  • AR: M4
  • AR: M16
  • SMG: AMR9
  • SMG: FSS Hurricane
  • LMG: 556 Icarus
  • Shotgun: Riveter
  • Battle Rifle: MTZ-762
  • Battle Rifle: FTAC Recon
  • Marksman Rifle: MTZ Interceptor

I’ll be sharing a finely tuned build for each weapon except the MCW (glitched; cannot equip), Riveter (incompatible with playstyle), MTZ-762 (too much recoil), and FTAC Recon (too much recoil). I tested each weapon extensively to find any way to make this attachment work and found great success with the majority! Here is a stress-tested, expertly crafted loadout for each weapon I recommend using the JAK Cutthroat on.

01 CTR MTZ-556.png

MTZ-556

  • Muzzle: Echoline GS-X
  • Barrel: MTZ PARA Long Barrel
  • Stock: JAK Cutthroat
  • Rear Grip: Bruen TR-24 Assault Grip
  • Underbarrel: Bruen Heavy Support Grip

The MTZ-556 has enjoyed a select few buffs recently, and the addition of the JAK Cutthroat is no exception. The MTZ has many ways to increase its mobility, but gaining so much from the Stock allows us to focus on reducing recoil and improving weapon performance. Reaching an incredible 3.7m/s Strafe Speed with reduced recoil and a massive +4 Firing Aim Stability, this build performs like a dream. It has ultra-consistent, predictable recoil – slowly veering left, so it requires you to build the muscle memory to begin compensating for that horizontal recoil by lightly pulling down and to the right. If you can manage that, you can take full advantage of an ultra-fast, super-smooth, highly capable weapon.

Compared to my previous Mathematically Optimized™ build, this version is nearly numerically the same – Damage Range, ADS, S2F, and Strafe are all the same, but with 3 extra points of Firing Aim Stability. Don’t be afraid of reducing your Damage Range with the Echoline GS-X since the MTZ carries the same TTK into its second Damage Range (as long as you hit 3 of 5 shots to the chest), up to 36 meters. Always remember that the MTZ-556 is more of an SMG than it is an AR, so treat your engagements as such.

02 CTR M4.png

M4

  • Muzzle: Zehmn35 Compensated Flash Hider
  • Laser: FSS OLE-V Laser
  • Stock: JAK Cutthroat
  • Rear Grip: Sakin ZX Grip
  • Underbarrel: Bruen Heavy Support Grip

The classic M4 always feels good to use in Call of Duty, so if you’ve missed it, the M4 has come back home. Featuring nearly perfectly-straight recoil along a steady climb, this build of the M4 is essentially as accurate as you are – if you can control it, you will be railing people without missing a bullet. Modern Warfare 2 guns still suffer from significant visual recoil, so the Zehmn35 combines with the Bruen Heavy Support Grip combine to strongly stabilize your sights, and the rest is pure fast handling. MW2 guns tend to feel bad to use in MW3, but not this one.

03 CTR M16.png

M16

  • Muzzle: Echoline GS-X
  • Optic: JAK Glassless Optic
  • Stock: JAK Cutthroat
  • Rear Grip: Sakin ZX Grip
  • Underbarrel: Bruen Heavy Support Grip

The M16’s recent buffs have crowned it as the best burst rifle in MW3, and it’s anticipated to potentially get even better with its incoming Conversion Kit. Allow this build to serve as a warmup before that Conversion Kit lands. The bursts carry a significant kick, and no matter how much recoil control you stack on the M16 (even with the JAK BFB), it simply has a built-in amount of Gun Kick that no combination of attachments can solve.

With that in mind, I’ve crafted a build that strongly reduces that kick and reigns in consistency over distance well. The JAK Glassless Optic appears to make a large difference on the M16 and is one of the best ways to reduce the recoil and improve your firing experience. It will be challenging to shoot right beyond 30 meters, so proactively compensate for recoil over midrange, but this build is essentially as consistent and accurate as possible while retaining decent handling.

04 CTR AMR9.png

AMR9

  • Muzzle: ECS Requieter Suppressor
  • Optic: JAK Glassless Optic
  • Stock: JAK Cutthroat
  • Rear Grip: Sakin ZX Grip
  • Underbarrel: Bruen Heavy Support Grip

The AMR9 is among the slowest of the SMGs and has always struggled with achieving decent handling numbers against good recoil, and the JAK Cutthroat really lends its strength to the AMR. This build is beautifully consistent – the only caveat being the strong, pronounced first-shot kick. If you can contain that initial muzzle rise, you should be impressed just how straight this SMG can shoot. 3.8m/s Strafe speed is absolutely outstanding for the AMR and is basically unheard of before this attachment, so the AMR serves as a shining example of just how powerful the JAK Cutthroat is.

05 CTR FSS Hurricane.png

FSS Hurricane

  • Muzzle: ECS Requieter Suppressor
  • Optic: JAK Glassless Optic
  • Stock: JAK Cutthroat
  • Rear Grip: Sakin ZX Grip
  • Underbarrel: Bruen Heavy Support Grip

In desperate need of a buff, the FSS Hurricane suffers from a horribly uncompetitive TTK (344ms) with no real distinguishing factor that sets it ahead of other SMGs. It does have a built-in 50-round magazine and can perform well at midrange where other SMG TTKs would falter, but ultimately falls behind the performance curve. Regardless, if you’re looking to try it, you can expect easily-controllable recoil with high consistency, but namely an excellent 3.8m/s Strafe Speed.

06 CTR 556 Icarus.png

556 Icarus

  • Muzzle: Zehmn35 Compensated Flash Hider
  • Optic: JAK Glassless Optic
  • Stock: JAK Cutthroat
  • Rear Grip: Sakin ZX Grip
  • Underbarrel: Bruen Tactical Vertical Grip

A slower version of the M4, but with all the same consistency and accuracy – just with a giant magazine. At around the 5th/6th shot, the recoil will suddenly swerve right, so be dial in the muscle memory to begin compensating left at about the fifth bullet and you’ll be able to laser people across the map. The rogue Bruen Tactical Vertical Grip makes a rare appearance to fix guns that only need Gun Kick or Firing Aim Stability (but neither Vertical nor Horizontal recoil) and is a crucial part of achieving that buttery-smooth, easily controllable firing profile. If you’ve been afraid of using Modern Warfare 2 guns in MW3 (and rightfully so), the 556 Icarus is another great one to try.

07 CTR MTZ Interceptor.png

MTZ Interceptor

  • Muzzle: Shadowstrike Suppressor L
  • Optic: Corio Eagleseye 2.5x
  • Stock: JAK Cutthroat
  • Rear Grip: Bruen TR-24 Assault Grip
  • Underbarrel: SL Skeletal Vertical Grip

I would not expect a Marksman Rifle to ever properly use attachments for fast handling, but this build of the MTZ Interceptor nails it. The JAK Cutthroat unlocks a new, refreshing, and rewarding playstyle for the Interceptor: one that utilizes the fast strafe speed to quickly peek to and from cover in attempts to land a one-shot kill to the head (lethal up to 38 meters). Similar to the M16, the MTZ Interceptor has an inherent amount of kick per shot that no blend of attachments will ever fix, so this build is designed to accentuate that mobile, opportunistic playstyle. 

Play fast, hit your shots, and play smart: make good use of that strafe speed to duck in and out of cover, taking potshots as it is safe to do so. It gives an immense feeling of satisfaction to only be visible to your enemies for a split-second, blindsiding them before they get instantly one-shotted and had practically zero chance to outgun you. If you aren’t able to land a headshot, make sure to center on the chest and pull down hard – you have an infinite two-shot, 280ms TTK as long as you hit both shots above the legs.

Our Testing Process: What does "Mathematically Optimized" mean? 

It means that I have personally conducted over 30 hours of dedicated testing across the entire MW2 & 3 attachment set, endlessly consulted high-quality external resources and databases, and tirelessly tested performance across separate attachment combinations to produce what I believe to be the optimal build of a weapon for a specific purpose. Weapons are carefully crafted considering every possible detail - attempting to deliver the mathematically best possible performance in every category - mobility, handling, recoil, range, and accuracy.

With my builds, I believe you should see creative, never-before-seen uses of attachments that create incredible weapons. Do keep in mind that these weapons will not do the work for you - while they have all been precision-crafted to reduce horizontal recoil as much as possible, some of them still have quite noticeable vertical recoil, and it is on you to manage that vertical recoil correctly. I sincerely hope you enjoy reading about this build and every other build I have to offer on Fanbyte!

DISCLAIMER: If you test these in the Firing Range, please note that the Firing Range is currently glitched and shows more visual recoil and different damage performance than actually experienced in-game; it is best that you test these in a custom match or online.
