About the M4A4 | Buzz Kill
M4A4 | Buzz Kill is a Covert skin that drops from one of the 42 CS2 weapon cases, the Glove Case.
Valve released the Glove Case on 28 November 2016.
Each open has a 0.3200% chance (about 1 in 313) of pulling it, as one of 2 Covert finishes. One in ten of those drops is StatTrak.
It sits in tier 4 of 5 (Mil-Spec to Rare Special) and ranks #22 of 41 finishes in the Glove Case by top-wear Steam price.
Its Steam price runs from $238.97 to $592.60 across wears, against $16.26 to open the Glove Case (case plus $2.50 key), so every wear is worth more than one open.
