The M249 | Spectrogram is an eye-catching Industrial Grade Machinegun skin that brings scientific visualization to the battlefield. With its distinctive green and blue halftone pattern, this skin transforms the reliable M249 into a visual representation of sound frequency data - truly “off the charts” as its description suggests.
The Spectrogram features a custom-painted finish with a mesmerizing green and blue halftone pattern that mimics the visual representation of audio frequencies. This scientific aesthetic gives the weapon a unique technical appeal that stands out from other M249 skins. The pattern flows seamlessly across the weapon’s surface, making it an excellent choice for players who appreciate both firepower and distinctive visual design.
The M249 | Spectrogram made its debut in CS2 on October 2nd, 2024, approximately 6 months ago. It was introduced as part of “The Armory” update and belongs to The Graphic Design Collection. As a Valve-designed skin, it maintains the high quality standards expected from official releases.
With an impressive popularity rating of 85%, the M249 | Spectrogram ranks within the top 15% of the most popular items in CS2. This measurement considers both daily sales volume and skin price. The skin is very affordable, with prices ranging from $0.05 to $0.14, making it accessible to players of all budgets. The Spectrogram is widely available across multiple marketplaces, ensuring easy acquisition for interested collectors.
The M249 | Spectrogram features a float value range of 0.00 to 0.50, allowing it to appear in all exterior conditions from Factory New to Battle-Scarred. This versatility gives players options to choose their preferred wear level according to budget and aesthetic preference. It’s worth noting that there are no StatTrak or Souvenir versions available for this particular skin.
The M249 itself is a strong open-area light machine gun that sacrifices fire rate for improved accuracy and substantial ammo capacity. While not the most popular weapon choice in competitive play, the M249 | Spectrogram adds visual appeal to this powerful suppression tool, making it more appealing for casual and specific tactical situations.
As part of The Graphic Design Collection, the M249 | Spectrogram stands alongside other visually striking skins that showcase various artistic and design elements. Unlike many other skins, the Spectrogram cannot be obtained by opening containers, making it somewhat unique in its acquisition method as a direct part of The Graphic Design Collection release.

Counter-Strike 2 has 1,349 weapon finishes, 603 knives, 94 glove finishes and 63 agents as of September 2026 - this wiki lists all of them on individual pages.
CS2 has 7 rarity tiers: Consumer Grade (white), Industrial Grade (light blue), Mil-Spec (blue), Restricted (purple), Classified (pink), Covert (red) and Contraband (orange) - plus the gold ★ Extraordinary tier for knives and gloves.
The M4A4 | Howl is the rarest CS2 skin: it is the only item ever given the Contraband tier, after Valve pulled it from the drop pool in 2014 over a copyright dispute, so its supply can only shrink.
Float is a number between 0.00 and 1.00 fixed when a skin is created, and it sets the skin’s wear level: Factory New 0.00–0.07, Minimal Wear 0.07–0.15, Field-Tested 0.15–0.38, Well-Worn 0.38–0.45, Battle-Scarred 0.45–1.00.
Floats above 0.95 are less common than middle values, and traders are willing to pay a lot for both extremes - the lowest floats in Factory New and the highest in Battle-Scarred. A float gets assigned to a skin upon opening and can’t change over time.
No, each finish has its own float range set by the designer: the AWP | Dragon Lore runs 0.00–0.70, so it never appears above that value, while some knives cap far lower.
The pattern index (or seed) is a number that decides where the finish texture lands on the weapon model; a Case Hardened skin has 1,000 possible seeds, and the high-blue “blue gem” seeds trade at 10–100× the price of an ordinary one.
CS2 cosmetics split into 14 types: knives, gloves, pistols, assault rifles, AWP, SMGs and heavy weapons on the weapon side, plus agents, cases and containers, charms, music kits, patches, pins and graffiti.
Yes, every CS:GO skin, sticker and case carried over to Counter-Strike 2 when the game replaced CS:GO on 27 September 2023, with upgraded models, and they trade exactly like items released after the switch.
Open the skin’s page in this wiki: it shows the current price at all five wear levels, how many listings are live at each level, and the float range that decides which levels the skin can reach.
The top of the market is Case Hardened items with rare blue patterns: an AK-47 | Case Hardened #661 in StatTrak Factory New sold for over $1,000,000 in June 2024, and the unique Factory New Karambit | Case Hardened #387, the only copy of its kind, has drawn offers as high as $1,500,000. Souvenir AWP | Dragon Lore rifles with rare Katowice 2014 sticker crafts have sold for over $150,000.
Yes, CS2 skins trade on third-party marketplaces for real money, unlike the Steam Community Market, where balance stays inside Steam.
