The M4A4 | Mainframe (Factory New) is a full-auto assault rifle favored by CTs for its accuracy, offering a more precise alternative to the AK-47. It features a striking black and white circuit board pattern, embodying a modern aesthetic.
The M4A4 | Mainframe was first introduced to CS2 on September 3rd, 2018, as part of the Austin 2025 Nuke Souvenir Package, coinciding with the "FACEIT 2018 – Ways to Watch" update.
This skin boasts an "Anodized Multicolored" finish style, primarily in shades of black and gray. The intricate circuit board design provides a unique and sleek look, enhanced by the multicolored candy coat applied through methods such as silk-screening or adherable stencils.
The M4A4 | Mainframe (Factory New) has a float value ranging from 0.00 to 0.07, ensuring a pristine appearance with no visible wear.
The price of the M4A4 | Mainframe has shown a steady increase over time, reflecting its popularity among players. Compared to other industrial-grade rifle skins, it remains competitively priced, making it a favorable choice for collectors and players alike.
As an Industrial Grade skin, the M4A4 | Mainframe is relatively common within the game, classified among 304 other rifle skins. This rarity indicates that while it is accessible, it holds a certain value due to its design and functionality.
The M4A4 | Mainframe can be obtained by opening containers such as the Antwerp 2022 Nuke Souvenir Package, Austin 2025 Nuke Souvenir Package, and Berlin 2019 Nuke Souvenir Package. Its drop chance is considered fairly common within the game.
With a popularity rating of 90%, the M4A4 | Mainframe is currently one of the most sought-after skins in CS2, driven by high daily sales volume and demand among players.
