The MAG-7 | Hard Water is a Mil-Spec-tier shotgun finish in Counter-Strike 2, originally introduced as part of The Operation Hydra Collection when the Operation Hydra Case launched in April 2017.

The float range for this finish is restricted to 0.00–0.45, so Factory New, Minimal Wear, Field-Tested, and Well-Worn are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

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 MAG-7 | Hard Water are tracked across 16 marketplaces, with prices spanning $4.22 to $102.87 depending on wear, variant, and seller.
