About the M4A1-S | Decimator
M4A1-S | Decimator is a Classified skin that drops from one of the 42 CS2 weapon cases, the Spectrum Case.
Valve released the Spectrum Case on 15 March 2017.
Each open has a 1.0667% chance (about 1 in 94) of pulling it, as one of 3 Classified finishes. One in ten of those drops is StatTrak.
It sits in tier 3 of 5 (Mil-Spec to Rare Special) and ranks #32 of 47 finishes in the Spectrum Case by top-wear Steam price.
Its Steam price runs from $13.44 to $58.44 across wears, against $7.52 to open the Spectrum Case (case plus $2.50 key), so every wear is worth more than one open.
