The M4 has a good amount of damage with moderate accuracy, it can be used both in a close and medium range to utilize its full potential.

More commonly known as AUG, the STB 556 is a beast assault rifle if you’re looking for something that has long-range potential. It is best for people looking for an assault rifle but also wants the perks of DMR and Snipers. Its reasonable recoil control further solidified this potential use as a long-range weapon. However, if you feel like taking it to another level, using attachments will allow you to almost get rid of the recoil and make it look like you are feeling no kickback at all.

However, with so many advantages, it needs to be nerfed in some way or another to make it balanced. That’s where we will talk about its DPS due to its lower fire rate. This forbids the weapon to be good up in close range just because of its lacking fire rate and burst potential.

Different from the other guns mentioned before, this gun shines due to its recoil and stability as an assault rifle. It is perfect for you if you like to keep distance between yourself and your enemies and perhaps like the feel of an assault rifle over any other category.

We will mention the Best add-ons below for the STB 556 to help substantially improve the weapon. This will boost the performance, and we will also mention the Magazine size.

If you want a low-skill but powerhouse of a gun, then look no further and go for the Kastov-74U. This small beast of a gun will surprise you with its light body and ability to act as an SMG while simultaneously being an Assault Rifle. With its high speed and relatively alright fire rate, it is great for running and gunning, and the damage is outrageous. It has a max damage of 77 to a minimum of 35, considering the limb hit.

The reason why it lands so low on the list is due to its bad recoil and considerably low fire rate. This enables its inability to mow down opponents with ease but can somewhat still prove to be a good weapon. However, the place where it lacks the most is most probably the range. It has very poor range and can still shoot at longer distances but is very much less effective. With a few attachments, this weapon will be on its way to being one of the top contenders in this list, and we can assure you of that.

Being a more close-quarter combat-oriented gun, you will definitely have fun sliding and shooting your enemies and dominating the close-range game. Also, the small size and light weight help with mobility, so even more bonuses.

We will mention the Best add-ons below for the Kastov-74U to help substantially improve the weapon. This will boost the performance, and we will also mention the Magazine size.


  1. Magazine: 30 Bullets
  2. Muzzle: RF Crown 50

  4. Grip: True-Tac Grip

Lachmann 556

Move Speed86%
Mag Size30

Almost similar to the M4 mentioned before but with a few tweaks here and there, and you have yourself the Lachmann 556. It is a perfect middle ground if you want something that has long range and has mediocre damage. It has a longer range than the M4 but lacks in the damage department and doesn’t hit as hard as the M4. Also, it has a very manageable recoil that is perfect for the long-range approach. So no need to swap to a different rifle style if you want something long-range; just go for the Lachmann 556.

The reason why the Lachmann 556 is this low on the list is that it is versatile but not the best at anything. For example, it might have good damage but is nowhere near the damage of the M4, while also having good accuracy and precision but still lacking compared to the STB 556. It might not be the best at anything, but being good at almost everything puts It on the list. However, if you want to use the Lachmann 556 to its true potential, stick around and check out its best attachments to utilize this gun fully.

The Lachmann 556 is a very straightforward and noncomplex gun, perfect for beginners as it has a high fire rate and relatively low damage output. Also, the low recoil helps you land shots easily, and the mobility you have with this gun is good as well.

We will mention the Best add-ons below for the Lachmann 556 to help substantially improve the weapon. This will boost the performance, and we will also mention the Magazine size.


  1. Magazine: 30 Bullets
  2. Muzzle: Echo line GS-X Suppressor

As the name suggests, the Kastov 545 is similar to the other Kastov Guns, especially the Kastov-74U. These guns are very similar to the point where their coexistence is questioned. But the place where the Kastov 545 differs from the Kastov-74U is the Damage output, recoil, and range. The Kastov 545 has Less recoil comparatively and has reduced damage due to it. Also, as the recoil decreased, you can now effectively use it at a longer range.

Now the reason for the Kastov 545 to be this low is due to the existence of the Kastov-74U. It is already the perfect weapon for up close range, and being an SMG that it puts the Kastov 545 in an awkward position where it feels like an SMG but, in actuality, is an Assault rifle. There already exists a better gun (Kastov-74U), so we would not recommend using this gun entirely, but if you still insist, we have some attachments that will change the gun entirely in your favor.

With a more manageable recoil and reduced damage along with better range and mobility, some players would prefer the Kastov 545 over the Kastov-74U and this decision is the players alone to make. We would urge you to try it out to see if it really is for you.

We will mention the Best add-ons below for the Kastov 545 to help substantially improve the weapon. This will boost the performance, and we will also mention the Magazine size.

The M16 has been a relatively well-known Assault Rifle for a long time and was most players’ first choice in previous games, but in Modern Warfare 2, it doesn’t even come close to being the best Assault Rifle. The damage output has been reduced a lot, and it doesn’t hit as it used to before. However, with the decreased Damage output, the Recoil has been decreased as well and you have more controllability over the gun alongside extra effective range. The M16 is truly a skill-based gun as it requires you to have good aim so you can land Head and body shots accurately. It has a burst-type style and can be a deadly weapon if in the right hands.

If you are the type of person that prioritizes accuracy over everything, then the M16 is perfect for you considering it has the best accuracy and recoil for long and medium ranges. We would recommend using some Attachments to make your M16 Experience better, and we will mention some below as well.

We will mention the Best add-ons below for the M16 to help substantially improve the weapon. This will boost the performance, and we will also mention the Magazine size.

TAQ-56 In-Game

The TAQ-56 comes last in the list because its existence is futile, considering we already have better options in the game. The main contender to the TAQ-56 is the M4, as it is better in every way possible. However, it isn’t completely obsolete due to the M4, it also has some advantages to using it. It has a very controllable recoil, along with good damage output and mediocre mobility. Also, It is very satisfying to get kills with it, but honestly, very hard to pick this over any other option because of how much better the other options are.

The TAQ-56 is an overall well-rounded Assault Rifle that is dependable in certain scenarios, but there are way better assault rifles to choose from as well. However, if you still want to use this AR, we would recommend using the Attachments we will share later.

We will mention the Best add-ons below for the TAQ-56 to help substantially improve the weapon. This will boost the performance, and we will also mention the Magazine size.


  1. Magazine: 30 Bullets
  2. Muzzle: Echoless-80
