Section 2: Best Assault Rifle Attachments Analysis

No matter your playstyle, your overall objective when building strong weapons should as best as possible adhere to the 3 tenets of an effective weapon: (1) maximum damage/range; (2) low recoil; (3) fast handling. You should strive to construct weapons that are versatile and adaptable, able to reflexively perform in a variety of situations. 6v6 weapons should be well balanced between speed and accuracy, Ground War weapons should slightly emphasize accuracy over speed, and Warzone weapons should sacrifice most speed for accuracy. The builds presented in this guide are constructed for effectiveness in the standard 6v6 multiplayer experience.


“I’m only using 2 or 3 attachments on my guns…” A reasonable conclusion to arrive to, and I don’t blame a large portion of the population for arriving at this resolution. Many people are sticking to the traditional Suppressor/Barrel/Magazine/Mobility template that has worked for years since MW19, and that simply doesn’t work this year. However, I've conducted extensive testing with the builds I present, and you should find that they work excellently with 5 attachments. It's all about avoiding the attachments at both ends of the spectrum: Some mobility attachments are too fast and give you too much recoil, and some recoil attachments are too heavy and slow you down too much. It's really difficult to find the niche attachments that give the most benefit for the least cost unless you perform very extensive testing like I do.


My understanding and insight on attachments is limited in the absence of advanced stats, but I base my knowledge on how attachments performed in MW19 and Vanguard (Vanguard operated on the MW19 engine). MW2 uses the MW19 engine, so it’s likely things are going to behave very similarly, if not exactly the same. Here is an explanation of the best attachments per slot for 6v6 (Not Ground War or Warzone):


  • Muzzle: +Horizontal/Recoil Control: Straight-up Vertical and Horizontal recoil control is pound for pound, stat for stat, the most powerful form of recoil mitigation (basis: Exact numbers from Vanguard), providing the strongest amount of reduction per point over any other types of mitigation, such as stabilization, steadiness, generic control, or anything of the such. I personally believe this to be the best recoil control attachment in the entire game.
    • Notice that this was Horizontal first, Vertical second. Attributes of an attachment are listed in order of strength, so if +Horizontal Recoil is listed first and Vertical second, the attachment will provide more Horizontal Recoil Control than Vertical Recoil Control.

    • What about suppressors?! Regardless of the current implementation of suppressors (showing up on the UAV while firing a silenced weapon with Ghost), I overall find the stealth benefits of suppressors to be far outweighed by the mobility penalties, and find them generally not worth using.

  • Barrel: Not Always Worth It: Barrels are variable per gun and, in some cases, are not even worth using because the penalty to mobility is significantly stronger than the benefits of recoil control, range, or velocity. Barrels are used on a gun-per-gun basis and usually when necessary to increase the range to 40 meters, a standard Assault Rifle breakpoint.

  • Laser: FSS OLE-V Laser: A penalty-free gain of ADS, Stability, and Sprint-to-fire. S-Tier attachment. The “con” to using this is that the laser is visible in ADS; if you are pre-aiming an area you believe an enemy will appear, aim at the wall closest to where they will appear so that your laser is not visible around the corner, and be ready to snap on-target.

    • What about stability? In Modern Warfare 2, Stability is active at all times, even when firing your weapon; this means that your weapon is always swaying up and down, side to side. I view Stability as a form of “soft recoil control” – and it’s disingenuous to refer to it as control, because it does not affect the amount of kick your weapon has; rather, an unstable weapon has a chance to sway you off-target even with perfect accuracy and recoil control; as such, a stable weapon has a better chance of staying on-target in the heat of battle. More important over medium-range encounters, very important for long-range encounters.

  • Optic: Preference, Otherwise Not Worth It: Try to get used to the Ironsights, but if you find them unbearable, you will be sacrificing something important. The attachment I would recommend cutting to add an Optic would usually be one that increases mobility at the cost of recoil control; these are usually Rear Grips.

  • Stock: Sometimes: Stocks are similar to barrels in that many of them harm your gun more than help it. However, Stocks are a precious source of mobility, and the +Strafe/Sprint Speed Stocks are excellent since they increase your mobility without harming recoil.

  • Rear Grip: Sometimes: Generally you don’t want to be sourcing your recoil control from the rear grip; rear grips tend not to affect the weapon heavily, but are a decent source of nominal mobility improvements.

  • Magazine: Never Worth It: Fast Hands is king this time around. Magazines tend to incur a heavy mobility loss on the weapon in every possible area - Movement Speed, Strafe Speed, ADS Speed, Sprint to Fire Speed, etc., - so the Fast Hands Bonus Perk is an MVP choice this year.

  • Ammunition: Never Worth It: Ammunition types simply do not provide enough benefit to justify an attachment slot when the nature of attachment balancing in this game is such a delicate dance; I liken the balancing of attachments in MW2 to balancing a nuclear reactor – too much heat (mobility) and you’ve got recoil plots akin to a runaway reaction; too much control, and you won’t get any productive amounts of power output. We simply must be using attachments that provide more value.

  • Underbarrel: +Recoil Stabilization: The Underbarrel slot is absolutely prized with the legendary FTAC Ripper providing incredible amounts of stabilization. This is a key attachment slot for any gun with an undesired amount of horizontal recoil; on almost every recommended build, I highly recommend this supremely powerful attachment to stabilize your recoil and focus it into a largely vertical plot, which is easier to control. The FTAC Ripper also provides an excellent amount of stability, another key stat for more distant engagements.

    • Special mention to the FSS Sharkfin 90 – free stability with no downsides. If you are not using an Underbarrel and have a free slot, use the FSS Sharkfin 90.

Section 3: Tuning Insight & Best Practices

I published a very detailed guide that explains the process, but for anyone not interested in learning how it works and just want the technique, I did also include a 60-second TL;DR video that teaches you everything you need to know.

Section 4: Bullet Velocity - Does It Matter in 6v6?

By and large, the answer is no, though there are exceptions. Players subscribe to many placebo-type myths that have been busted (such as velocity giving better hitreg – false), and for most primary weapons, Velocity largely does not matter and will almost never be the defining factor of a 6v6 gunfight. Velocity largely comes into play when engaging horizontally moving targets in which your velocity may be too slow and force you to horizontally lead a target, but this largely applies over distances well exceeding 40 meters.

Every Assault Rifle has a base velocity of 590ms, which requires no lead up to 50 meters, and minimal lead beyond 60 meters. Again, remember that this is largely horizontal lead. I only recommend the High Velocity attachment for Longshots due to the 38-meter minimum engagement range for AR Longshots, which edges a bit close to requiring lead. With no other attachment considerations, the High Velocity attachment will make it so you should not have to lead any targets (vertically or horizontally) under 70 meters.

Section 5: Recommended Loadouts, with Tuning

In this section I’ll provide my highly-tested and confirmed-effective loadouts that are a result of many hours of testing in live matches, bot matches, shooting walls to observe recoil plots, and messing with tuning. You may not be able to build these weapons early or until the weapon is fully leveled; remember, Tuning is not unlocked until the weapon is maximum level. Be sure to refer to my earlier Attachment Unlock List to scavenge for missing attachments – especially the laser from the EBR.

M4A1 recommended build with Simplified Tuning and challenges.
  • M4A1

    • Difficulty level: Easy

    • The classic, iconic M4A1 is back, but this time it isn’t quite the supreme overlord it traditionally has been. The M4 struggles with extreme amounts of visual recoil and high vertical and horizontal recoil, but is an otherwise well-rounded, all-purpose AR. Expect hitmarkers over range due to the M4A1’s lower native range of 26 meters (A barrel is added to extend the range to 31m).

      • Level 08: 50 ADS

      • Level 13: 10 Double Kills

      • Level 19: 15 Kills from behind

    • Unlocked at: Player Level 1

Taq-56 recommended build with Simplified Tuning and challenges.
  • Taq-56

    • Difficulty level: Easy

    • The Taq-56, also formally known as the SCAR, is a high-powered mobility machine with excellent accuracy and low recoil.

      • Level 08: 10 Double Kills

      • Level 13: 50 ADS Kills

      • Level 19: 15 Hipfire Kills

    • Unlocked at: Player Level 19

Kastov 762 recommended build with Simplified Tuning and challenges.
  • Kastov 762

    • Difficulty level: Easy

    • The Kastov 762, also formally known as the AK-47, is a traditionally slower but heavy-hitting AR, but thanks to its native damage range of 45 meters we go completely barrel-less and accelerate the handling into absurd levels without compromising the outstanding recoil profile.

      • Level 08: 20 Mounted Kills

      • Level 14: 50 ADS Kills

      • Level 19: 20 Kills from Behind

    • Unlocked at: Player Level 23

Lachmann-556 recommended build with Simplified Tuning and challenges.
  • Lachmann-556

    • Difficulty level: Medium

    • The Lachmann-556 is a lower-damage option that will straight-up get outgunned; you simply have to accept that. Approach this weapon like the M13B: Weaker, but absolutely laser-accurate with respectable handling.

      • Level 08: 10 Double Kills

      • Level 14: 50 Kills with a Suppressor

      • Level 19: 10 Hipfire Kills

    • Unlocked by: Leveling the Lachmann-762 (BR) to level 13.

      • Lachmann-762 Battle Rifle unlocked at Player Level 16.

STB 556 recommended build with Simplified Tuning and challenges.
  • STB 556

    • Difficulty level: Easy

    • The STB 556, also formally known as the AUG, can be configured to be a complete aggression master with excellent handling speeds, but poor range. With a lacking native range of only 16 meters, expect hitmarkers frequent and often, but play to its strengths as an SMG and you should find it very rewarding. A barrel is not considered due to the nominally low range and the fact that the longest barrel significantly disservice’s the weapon’s handling.

      • Level 08: 20 Mounted Kills

      • Level 14: 10 Double Kills

      • Level 19: 30 Crouched Kills

    • Unlocked at: Player Level 41

M16 recommended build with Simplified Tuning and challenges.
  • M16

    • Difficulty level: Medium

    • After the significant buff, the M16 has become relatively consistent and usable with a decently expectable one-burst potential.

      • Level 06: 10 Double Kills

      • Level 11: 30 Crouched Kills

      • Level 15: 20 Mounted Kills

    • Unlocked by: Leveling the 556 Icarus (LMG) to level 13.

      • 556 Icarus (LMG) unlocked by: M4A1 (AR) to level 18

      • M4A1 Assault Rifle unlocked at: Player level 1

Kastov-74u recommended build with Simplified Tuning and challenges.
  • Kastov-74u

    • Difficulty level: Easy

    • The Kastov-74u, also formally known as the AK-74u, is another in-your-face mobility master configured as an SMG. Handling is exceptional and recoil is minimal; an absolute slapper.

      • Level 08: 15 Point-Blank Kills

      • Level 14: 10 Double Kills

      • Level 20: 30 Crouched Kills

    • Unlocked by: Leveling the Kastov 545 (AR) to 13

      • Kastov 545 Assault Rifle unlocked by: Kastov 762 (AR) to level 10

      • Kastov 762 Assault Rifle unlocked at: Player level 23

Kastov 545 recommended build with Simplified Tuning and challenges.
  • Kastov 545

    • Difficulty level: Easy

    • The newly-buffed Kastov 545 brings great handling speeds, low recoil, and an acceptable TTK.

      • Level 07: 10 Hipfire Kills

      • Level 13: 50 ADS Kills

      • Level 20: 50 Kills with a Suppressor

    • Unlocked by: Leveling the Kastov 762 (AR) to level 10.

      • Kastov 762 Assault Rifle unlocked at: Player level 23.

M13B recommended build with Simplified Tuning and challenges.
  • M13B

    • Difficulty level: Hard

    • The M13B is a total yikes. Woefully ineffective at any range and a complete sponge. Very accurate, but I personally rate it to be the worst AR.

      • Level 09: 10 Double Kills

      • Level 15: 15 Point Blank Kills

      • Level 19: 15 Kills from Behind

    • Unlocked by: Exfiltrating with the M13B in DMZ.

Chimera recommended build with Simplified Tuning and challenges.
  • Chimera

    • Difficulty level: Medium

    • A faster, less accurate version of the M13B and a similar low-range offering, but more effective. An AR/SMG hybrid.

      • Level 09: 20 Hipfire

      • Level 15: 10 Double Kills

      • Level 17: 15 Kills from Behind

    • Unlocked by: Earning two kills with Assault Rifles in 15 different matches, or Exfiltrating with the Chimera in DMZ.
