Modern Warfare 2: Best Assault Rifle & Loadouts [Season 6]

After spending over 100 hours in MW2, here is my recommendation for the best Assault Rifles.

Assault Rifles are fast, versatile, and can be used in all sorts of combat range engagements while playing COD MW2. Having the knowledge of the best weapons, and how to unlock guns and attachments gives you an edge while playing multiplayer mode. However, if you’re an AR FPS player, then you should know about the Modern Warfare 2 Best Assault Rifle in the current meta. 

Key Takeaways
  • Assault Rifles are very versatile and fast and can be used in all kinds of engagements in COD Modern Warfare 2.
  • Each Assault Rifle has its own characteristics and differs from one another in terms of performance.
  • The selection of the right AR depends on the fighting style of a player.
  • However, to fully utilize their prowess, player will need to equip the optimal attachments for each AR in MW2.

Kastov 762

  • Why I Chose This: Fast Time to Kill (TTK) in close-range combats.

The assault rifle known as the Kostov 762 is a vital component of the AK platform. It has a large caliber chamber with a 7.62 x 39mm diameter that can hold bullets, and it can deliver powerful shots in the hands of skilled players. On the other hand, both the precision and the recoil control of this weapon are below average.

You have the ability to choose between two different firing modes: full-auto and semi-auto. On the other hand, and this should come as no surprise, you will be employing the latter for brief bursts in order to guarantee precision in MW2.

It is hard for me to resist mentioning the Kastov 762 when a discussion about the finest assault rifles is taking place. This is one that is sure to stick out above the others in the metagame because of its powerful kick and weighty feel overall.

  • Why I Chose This: Suitable for all types of ranges with decent recoil control.

The Lachmann 556 is an excellent main weapon for both long and short-range combat. The gun, in general, is straightforward to use, whether for seasoned gamers with years of experience or for newcomers to MW2 as well. Because of its high rate of fire and relatively low total damage per shot, it is most useful at medium to long ranges.

Since it has a relatively low recoil, you’ll be able to steadily and consistently follow and attack your foes from a great distance. Recoil is controlled, and the quick mobility that can be achieved with this choice makes it a very important weapon to have in your inventory.

Best M16 Loadouts in COD Modern Warfare 2

  • Why I Chose This: Best option for burst-fire lovers.

In Call of Duty: MW2, the M16 is an excellent choice for a weapon to use if you are skilled at shooting head or body shots. In the event that you desire to hone your targeting skills, you may utilize the weapon for that purpose as well. Bear in mind, though, that there will be a little pause in between each burst of activity on your part.

The M16 is one of the best Assault Rifles in Call of Duty MW2 under the burst weapon category, and it plays quite similarly to the other iterations of the M16 that have been included in past Call of Duty games. 

Therefore, if you want great accuracy, you will need to utilize the M16 at medium to long ranges. This is the only way to do this. It is imperative that you refrain from utilizing the M16 while you are in a confined space. If it does not happen, all you will be doing is firing rounds into the air.

Weapon Stats

  • ADS Time: 290 ms
  • Muzzle Velocity: 590 m/s
