M4A4 | Buzz Kill

Origin Story

The M4A4 | Buzz Kill brings a burst of industrial aggression to Counter-Strike’s rifle lineup. Introduced with The Glove Collection on 29 November 2016 during the “Brothers in Arms” update, this design is a product of Sektor Industry’s fictional firearms division – a recurring motif among high-tech, militarized skin lines. Its mix of matte black, carbon fiber, and bold yellow panels creates a utilitarian yet stylish finish, resembling a tool forged for elite operations rather than vanity.

Drop Chance

Following Valve’s official case rarity data:

Total Covert-tier probability: 0.64%
The Glove Case features two Covert weapons – the M4A4 | Buzz Kill and the Dual Berettas | Royal Consorts.
Therefore:

Individual drop rate: 0.64% ÷ 2 = 0.32%

StatTrak™ chance: 10% of base = 0.032%
These odds equate to roughly a 1 in 312 case openings chance to unbox Buzz Kill, placing it alongside other mid-era Covert rifles in rarity.

Skin Condition

Float Range: 0.00 – 0.70

• Available Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred
• Buzz Kill’s color saturation declines progressively with wear – from glossy yellow vibrance at low floats to muted mustard and scuffed blacks at higher ones. Despite visible wear on handguard and magwell, the weapon maintains a strong, battle-worn industrial appeal even in Battle-Scarred condition.

Model

Model: CS:GO (Legacy)
Added: 29 November 2016
Update: “Brothers in Arms”
The M4A4 | Buzz Kill was originally optimized for the CS:GO engine but transitioned seamlessly into CS2, where the yellow finish now benefits from higher dynamic contrast and reflective detail under Source 2’s lighting. Though a legacy model, it retains its mechanical polish and industrial identity – a symbol of pre-CS2 design precision.

How to Obtain

Buzz Kill is a Covert-grade rifle from the Glove Case, one of the most recognizable weapon cases from CS:GO’s mid-era. It’s obtainable through case openings, available in both standard and StatTrak™ variants. The case remains openable in CS2, though with limited drop rotation, making Buzz Kill an increasingly valuable pull as its case becomes rarer in circulation.

Price Range

$124.12 – $937.45
Market trends show significant price stratification between exteriors. Factory New variants command premium valuation due to clean yellow paneling, while Field-Tested and Well-Worn offer lower-cost alternatives for budget collectors. StatTrak™ Factory New listings are particularly scarce, adding to long-term speculative demand.

Visual Theme

Finish Style: Gunsmith
Finish Catalog: 632
The design channels modern military industry, mixing polymer textures, honeycomb plating, and Sektor Industry decals. Its Flavor Text, “There’s one at every party,” hints at the rifle’s bold personality – both confident and impossible to ignore. It’s a weapon designed for dominance, both in-game and on display.
