M4A4 vs M4A1-S: Which Rifle is Better in CS2?

February 26, 2025

The M4A4 and M4A1-S are the two primary rifles available for Counter-Terrorists (CTs) in CS2, each offering distinct advantages and drawbacks. Choosing the right rifle is crucial, as it directly impacts playstyle, positioning, and overall effectiveness in engagements. The M4A4 excels in aggressive plays and multi-frag situations, while the M4A1-S is favored for stealth, precision, and economy-friendly gameplay. Over time, balance updates and meta shifts have influenced the popularity of both rifles, with changes to damage, magazine size, and economy affecting how players approach their selection in competitive play. Understanding these factors can help players optimize their performance and adapt to evolving game mechanics.

Key Differences Between M4A4 and M4A1-S

Magazine Size: The M4A4 has a larger magazine size of 30 rounds, while the M4A1-S is limited to 20 rounds. This difference significantly impacts extended fights and multi-kill potential. The M4A4’s higher capacity allows players to spray more freely, making it a better choice for retakes, holding aggressive angles, and fighting multiple opponents. On the other hand, the M4A1-S’s smaller magazine requires players to be more precise with their shots, as running out of ammo mid-fight can be costly.

Damage & Armor Penetration: Both rifles deal similar base damage, but the M4A1-S has higher armor penetration, making it slightly more effective against armored opponents. In most cases, both rifles require four body shots to kill an enemy with armor, but the M4A1-S’s slightly higher damage can help secure kills faster if shots are well-placed. The M4A4, however, provides better consistency in fast-paced engagements, as its higher fire rate compensates for any minor damage difference.

Fire Rate & Time to Kill (TTK): The M4A4 has a fire rate of 666 RPM (rounds per minute), whereas the M4A1-S fires at 600 RPM, making the M4A4 faster in close-range combat. This higher fire rate reduces its time to kill (TTK), meaning M4A4 users can eliminate enemies slightly quicker in head-to-head duels. The M4A1-S, while slower, compensates with greater accuracy, making it more effective for burst-firing and controlled engagements.

Recoil & Spray Pattern: The M4A1-S has lower recoil and a more controlled spray pattern, making it easier to handle for players who prefer accuracy over volume of fire. Its simpler recoil pattern allows for easier headshot control, making it an excellent choice for holding angles and tapping at long ranges. In contrast, the M4A4 has a higher recoil and a more unpredictable spray pattern, which requires better spray control and muscle memory. However, in the hands of skilled players, the M4A4’s faster fire rate and higher magazine size make it more versatile in aggressive fights.

Silencer Advantage: The M4A1-S comes with an integrated silencer, which offers multiple tactical advantages. Silenced shots are harder for enemies to locate, making it easier to hold positions without giving away your location. This is especially useful in clutch situations, flanking, and post-plant scenarios. However, the silencer also slightly reduces bullet velocity and damage over range, which can be a disadvantage in long-distance fights. The M4A4, without a silencer, has a louder firing sound, making it easier for enemies to react, but it does not suffer from damage drop-off at long range.

Price & Economy: The M4A4 costs $3,100, while the M4A1-S is cheaper at $2,900, making the latter a more economical choice in competitive play. The lower price of the M4A1-S allows Counter-Terrorist teams to buy utility (grenades, defuse kits) more easily during full-buy rounds. However, the M4A4’s larger magazine and higher fire rate make it a better long-term investment for players who prefer aggressive and high-kill potential playstyles.

These key differences define how each rifle is used in CS2 competitive play, with the M4A4 being better for aggressive multi-frag engagements and the M4A1-S excelling in stealth and precision-focused strategies.
