M4A1-S | Dark Water was added to the game on August 14, 2013, as part of The Arms Deal Collection. The skin was created by Valve designers.
The body of the rifle is coated with a chrome base and adorned with a pattern of wavy lines made in matte gray. The barrel and a part of the buttstock are painted solid black.
Float Value of M4A1-S | Dark Water ranges from 0.10 to 0.26, which makes the skin available only in Minimal Wear and Field-Tested condition. At low wear levels, little abrasions appear on the handguard, buttstock, and receiver. In Field-Tested condition, abrasions are present in all parts of the weapon except the silencer, but they only slightly affect the appearance of the skin, as most of them merge with the pattern.
The pattern index affects the arrangement of the wavy lines on the body of the rifle.
The quality of M4A1-S | Dark Water is Restricted. The skin has a StatTrak option and belongs to the "Dark Water" series
The skin was popular after the release, but today it is almost forgotten.
