About the M4A1-S | Cyrex
M4A1-S | Cyrex is a Covert skin that drops from one of the 42 CS2 weapon cases, the Operation Breakout Weapon Case.
Valve released the Operation Breakout Weapon Case on 1 July 2014.
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 #15 of 27 finishes in the Operation Breakout Weapon Case by top-wear Steam price.
Its Steam price runs from $201.68 to $251.78 across wears, against $13.26 to open the Operation Breakout Weapon Case (case plus $2.50 key), so every wear is worth more than one open.
