Released in November 2014 via the Operation Vanguard Weapon Case, the G3SG1 | Murky sits at the Mil-Spec tier within The Vanguard Collection.

The float range for this finish is restricted to 0.00–0.25, so Factory New, Minimal Wear, and Field-Tested are the only obtainable conditions on the open market. Battle-Scarred examples are not produced, so the most worn copies still retain a relatively clean appearance.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for G3SG1 | Murky are tracked across 16 marketplaces, with prices spanning $0.76 to $94.84 depending on wear, variant, and seller.
