Released in July 2014 via the eSports 2013 Winter Case, the M4A4 | X-Ray sits at the Covert tier within The eSports 2013 Winter Collection.

The float range for this finish is restricted to 0.00–0.30, 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 M4A4 | X-Ray are tracked across 17 marketplaces, with prices spanning $73.17 to $337.00 depending on wear, variant, and seller.
