The M4A1-S | Dark Water is a Restricted-tier rifle finish in Counter-Strike 2, originally introduced as part of The Arms Deal Collection when the CS:GO Weapon Case launched in September 2013.

The float range for this finish is restricted to 0.10–0.26, so Minimal Wear and Field-Tested are the only obtainable conditions on the open market. Factory New examples are not produced for this skin — even the cleanest copies will show some surface texture.

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 M4A1-S | Dark Water are tracked across 17 marketplaces, with prices spanning $67.89 to $228.00 depending on wear, variant, and seller.
