The STB 556 differs from other assault rifles in that it can be fitted with a large number of different attachments. You have a lot of leeway to personalize it in accordance with your own tastes.

The M4 will constantly have your back, whether you need it for long-range elimination of an opponent or for close-quarters combat scenarios.

In Modern Warfare 2, the M4 serves as the first AR. It is important to note that increasing its level will allow you to obtain more Assault Rifles as you advance throughout the game, such as the M16. This will be accomplished by increasing its overall level.

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.

Simply reaching level 13 with the Lachmann 762 is all that is required to open up access to the Lachmann 556. The Lachmann 762 is another excellent choice for a beginning weapon, and it is quite simple to advance its level.

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. You will have access to a three-round burst assault while using the M16.

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. It is imperative that you have the ideal loadout for your M16 if you plan on using it as your primary weapon.

Weapon Stats

  • ADS Time: 290 ms

Kastov-74U MW2

The Kastov-74U is one of the most powerful weapons in the game, albeit having its own set of advantages and disadvantages. There are no drawbacks to the AR that, with the addition of the appropriate attachments and perks, cannot be countered. It is a simple firearm that can inflict significant damage when used up close, yet it may also be used well at longer ranges.

The Kastov-74U’s range is the only potential drawback we have while thinking about this weapon. However, despite the fact that it is still fairly excellent at long range, it is not the strongest. Due to variables like its range and firing rate, it is difficult to employ effectively at long ranges in combat situations. You may still take advantage of it, but you’ll need to have excellent skills in FPS combat to land more kills.

Having said that, it is very possibly the most effective close-range weapon currently available in the game. There is no other submachine gun or assault rifle that even comes close to competing with the Kastov-74U; at least, that is what most writers at eXputer think.

Weapon Stats

  • Fire Rate: 652 RPM
  • ADS Time: 210 ms
  • Muzzle Velocity: 590 m/s
  • Ammo Count: 30
  • Sprint To Fire Time: 210ms 

Best Kastov-74U Loadout

  • Barrel: BR209 Barrel
  • Underbarrel: Merc Foregrip
  • Stock: Markeev R7 Stock
  • Grip: True-Tac Grip
  • Perk 1: Battle Harden
  • Perk 2: Double Time
  • Bonus Perk: Focus
  • Ultimate Perk: Quick Fix
  • Equipment: Flash Or Stun
  • Lethal: Semtex
  • Field Upgrade: Dead Silence


TAQ-56 MW2 Loadout

When contrasted against either the Kastov or the M4, the TAQ-56 is a powerful weapon that also has certain advantages. The AR may be carried together with any of the other two weapons with ease. The TAQ-56 as a whole is well-rounded, and selecting an AR out of the several options available ultimately boils down to a matter of personal opinion. 

The TAQ-56, in comparison to the Kastov 762, is, according to the widespread opinion of professional Call of Duty broadcasters on Twitch and YouTube, the lesser weapon. However, despite its flaws, it is still a dependable and powerful rifle that has a respectable time to kill and strong handling metrics.

The damage-to-recoil ratio is the primary topic of discussion here. While the Kastov can do a lot of damage, it is difficult to control from a distance. In contrast, the M4 has a high level of precision and excellent control over its recoil.

Since of the variety of attachments that are detailed below, this TAQ-56 loadout is the most effective one that we’ve seen so far because it achieves an excellent balance between minimal recoil and strong stopping power. 

Weapon Stats

Players are able to exercise greater levels of command because of the smaller 5.45mm bullets that are fired by the Kastov 545. When shooting the weapon for an extended amount of time, you will find that this is a superb AR. The Kastov 545 and the Kastov-74U are extremely comparable to one another. The most important distinction is that it does somewhat less damage but has a longer range and less recoil than its predecessor.

If you want to keep your foes at bay at a safe distance, the Kastov 545 Assault Rifle is an excellent choice. It offers a high rate of fire and excellent accuracy. In addition to that, it has a rapid firing rate, which enables it to wipe out foes in a very short amount of time. The weapon is designed to be very effective at medium to close ranges of combat.

Despite the fact that this weapon is not presently a dominant AR in the metagame, it is still a fantastic rifle that allows you to construct the optimal loadout to shred your opponents.
