Bottom line: Three weapons decide most of professional Counter-Strike. Across 6,677,283 pro kills in our data (all eras, as of 10 July 2026), the AK-47 accounts for 35.7%, the M4 platform for ~24%, and the AWP for 10.7%, roughly seven in ten kills. The rifles are headshot machines (the AK lands 57% of its kills in the head); the AWP barely bothers (9.3%), because one torso hit already kills. Every figure here comes from the EsportsOdds CS2 data API.
The three guns that matter
Counter-Strike has dozens of weapons, but the kill distribution is brutally top-heavy. Here is the share of pro kills by weapon (the roster and its tuning are set by Valve's CS2 patch notes):
The AK-47 alone is responsible for more than a third of the pro kills we track. Add the two M4 variants (the M4A1-S and M4A4, ~24% combined) and the AWP (10.7%), and those three weapon classes cover around 70%. Everything else, from pistols and SMGs to the Galil, FAMAS and grenades, splits the remaining third. These shares come from every pro match we record (as of 10 July 2026); weapon-stat coverage lags a little behind match coverage, so we don't claim it is complete.
This is why the "rifle round" is the unit of Counter-Strike: once both teams can afford their primary rifles, the game is largely decided by who wins the AK-and-M4 duels. The AK's edge is that it kills with a single headshot even through armour, where the M4 does not, a small mechanical difference that shapes which side wants to take fights.
Headshots: the AWP is the exception
Where a weapon lands its kills says a lot about how it's used. Rifles reward precision; pistols reward it even more; the AWP ignores it entirely:
The story in one chart:
- Pistols are headshot weapons. The USP-S lands 84.6% of its kills in the head and the Glock 79.5%: because their body damage is low, a pistol kill almost has to be a headshot.
- Rifles are in the middle. The AK-47 sits at 57.2% (its one-shot-headshot reward pulls players to aim high), the M4A4 at 46.3%, the M4A1-S lower at 39.6%.
- The AWP is the outlier at 9.3%. It kills with one shot almost anywhere on the body, so there is no reason to risk the smaller target. The AWP's low headshot rate isn't inaccuracy; it's the weapon working exactly as intended.
That single 9.3% figure captures why the AWP changes how a round is played: it removes the duel. A rifler has to win an aim battle; an AWPer just has to see you first.
The AWP is a CT weapon
The AWP's kills are not evenly split between the two sides. Nearly two-thirds come on the Counter-Terrorist side:
That 63.8% CT / 36.2% T split follows from how the weapon is used. On defence, a CT AWPer can hold a long angle, take one pick, and fall back, a low-risk, high-reward play. On attack, a T-side AWPer has to push into those angles, where the slow rifle and long scope-in are a liability. The split is consistent with a piece of common Counter-Strike wisdom, that the AWP earns its value defensively, though a side-split in kills illustrates that pattern rather than proving it.
It also connects to map balance. Maps with long, AWP-friendly sightlines tend to be more CT-sided, because the same weapon that struggles to entry is deadly holding, one reason side win-rates vary so much from map to map.
The tail: what fills the other third
The big three take roughly seven in ten kills, so what accounts for the rest? Below the AK, M4 and AWP, the count fragments fast across situational buys:
The next rung down is a mix of a second rifle, the two starting pistols and an SMG. The USP-S (4.9%) and Glock-18 (4.1%) are the CT and T starting pistols: they carry the pistol round and the eco round, which is why they rack up kills despite being nobody's rifle of choice. The Galil AR (4.4%) is the T-side budget rifle bought on a broken economy, and the MP9 (3.2%) is a CT anti-eco SMG. These four are only a slice of the tail, since the Deagle, FAMAS, other SMGs and grenades fill the rest and we don't claim our weapon coverage is complete. But they show the shape: beneath the headline rifles, kills scatter across whatever a thin buy can afford.
Getting weapon data from the API
Per-weapon kills, headshots, and side splits are all available through the EsportsOdds CS2 data API, down to the individual player and match, computed the same way every time (see the methodology). That's what you'd build a weapon-usage dashboard, an AWP-impact model, or a "which gun won the round" breakdown on, as clean JSON on a flat $99/month plan.
The AK (36%), M4 (24%) and AWP (11%) cover ~70% of pro Counter-Strike kills. Rifles and pistols are headshot weapons; the AWP lands just 9% headshots because a torso hit already kills. And 64% of AWP kills come on the CT side, where it holds angles rather than entries.
Frequently asked questions
What is the most-used weapon in CS2?
By kills, the AK-47, which accounts for 35.7% of the pro kills we track, more than any other weapon by a wide margin. The M4 platform is second (~24% combined) and the AWP third (10.7%).
Why does the AWP have such a low headshot rate?
Because it kills with a single shot to the body. There's no need to aim for the smaller head target, so AWPers take the higher-probability body shot, which is why its headshot rate is just 9.3%, far below every rifle and pistol.
Is the AWP better on CT or T side?
CT. About 63.8% of AWP kills in our data come on the Counter-Terrorist side, where the weapon can hold angles defensively at low risk, versus 36.2% on the more aggressive T side.
Which weapons decide most CS2 rounds?
The AK-47, the two M4 variants, and the AWP, together roughly 70% of the kills we track. Once both teams can afford rifles, the rifle-and-AWP duels largely decide the round.
Where can I get CS2 weapon statistics via an API?
Through the EsportsOdds CS2 data API: per-weapon kills, headshots and side splits as JSON on a flat $99/month plan. It's the clean input for an AWP-impact study, a per-gun win-rate model, or a weapon-usage dashboard, without scraping a stats site.
