M4A1-S | Master Piece is a graffiti-styled rifle skin introduced on July 1, 2014, released as part of Copenhagen 2024 Overpass Souvenir Package during the "Operation Breakout" update. It has been painted in a “Custom Paint Job” style, with the Master Piece finish, covering the rifle in layered street-art lettering and bold color work. A cool blue base is wrapped in abstract tags, patterns, and splashes of warm tones, giving the suppressed M4A1-S a rebellious, urban vibe that stands out without looking messy. The design is consistent across pattern indexes, so the artwork remains recognizable on every drop. In Factory New condition, it appears pristine: virtually no scuffs, scratches, or worn edges, so the colors stay vivid and the fine graffiti details remain crisp.
