MP9 | Buff Blue

MP9 | Buff Blue released March 31, 2025 as part of the Ascent Collection.

It's a Counter-Strike 2-native release, launched after Valve's September 2023 relaunch, with no CS:GO history of its own.

It launched as a Consumer Grade finish, with a Souvenir edition but no StatTrak™ version.

As a finish, "Buff Blue" is applied to the MP9 — the Counter-Terrorists' fast-firing, low-cost submachine gun — and carries the grey rarity color every Consumer Grade skin shares on the Steam Market and in-game.

That Consumer Grade classification places it among the most common tiers in CS2 — a rank that only appears in Collections, never in a Case's own drop pool.

MP9 | Buff Blue ships in all five wear conditions, but its float is capped between 0.00 and 0.70 — narrower than the full 0.00–1.00 range some other skins allow.

As with every CS2 skin, lower float values look cleaner: Factory New copies (roughly below 0.07 float) show the finish at its sharpest, while Field-Tested and Well-Worn pieces make up the most commonly traded middle ground between mint and heavily worn.

MP9 | Buff Blue is part of the Ascent Collection rather than being unboxed from a traditional weapon Case — the Collection is currently cycling through CS2's weekly Prime drop pool, so trade-ups and the Steam Community Market are the main ways to acquire one.

Valve has never published exact Collection odds. The estimate above (1 in 14, 7.2751%) applies the same rarity-tier cascade confirmed for Cases, giving a general sense of scale rather than a guaranteed rate.

Alongside the Normal version, this finish also has a Souvenir edition — there's no StatTrak™ counterpart.

Beyond that, there's no separate "phase" or pattern family tied to this finish in the site's data — it's tracked as a single fixed look across every wear condition it ships in.

As a Consumer Grade finish, MP9 | Buff Blue sits among the more common pulls from the Ascent Collection rather than being a chase item — a straightforward, affordable way to add a MP9 skin to a loadout or collection.

Its Souvenir edition tends to trade at a premium over the Normal version, the same pattern seen across most CS2 skins with that variant available.

MP9 | Buff Blue has been part of the Ascent Collection since March 31, 2025 — a Counter-Strike 2-native release with no CS:GO-era version to compare it to.

It's one of 11 Consumer Grade items in the Ascent Collection, out of 28 items total.

This is one of 47 MP9 skins currently listed on the site, spanning multiple rarity tiers.
