MP5-SD | Gauss

MP5-SD | Gauss released March 13, 2019 as part of the Prisma Case.

It originally released during the CS:GO era, before Valve's Counter-Strike 2 relaunch in September 2023 — its artwork, wear range, and source carried over unchanged into CS2.

It launched as a Restricted-tier finish, with both a StatTrak™ and a Souvenir edition.

As a finish, "Gauss" is applied to the MP5-SD — a suppressed submachine gun added in Counter-Strike 2, effective in close-quarters engagements — and carries the purple rarity color every Restricted-tier skin shares on the Steam Market and in-game.

That Restricted classification places it in the middle of the rarity ladder — rarer than Mil-Spec Grade, but short of the Classified and Covert tiers above it.

MP5-SD | Gauss ships in all five wear conditions, from Factory New through Battle-Scarred, across the full 0.00–1.00 float range.

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.

MP5-SD | Gauss comes from the Prisma Case — the Case is no longer part of the active drop pool, so trading and the Steam Community Market are the ways to acquire it today.

Valve's own published Case odds put a Restricted-tier pull like this one at roughly 1 in 31 (3.1960%).

There's both a StatTrak™ and a Souvenir edition of this finish, alongside the Normal version — three ways to own the same look, differing only in that badge.

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 Restricted-tier finish, MP5-SD | Gauss sits among the more common pulls from the Prisma Case rather than being a chase item — a straightforward, affordable way to add a MP5-SD skin to a loadout or collection.

Its StatTrak™ and Souvenir editions tend to trade at a premium over the Normal version, the same pattern seen across most CS2 skins with that variant available.

MP5-SD | Gauss has been part of the Prisma Case since March 13, 2019, and like every CS:GO-era CS2 skin, carried over unchanged when Valve relaunched the game on the Source 2 engine in 2023 — the artwork, wear range, and source Case/Collection are the same today as they were before the migration.

It's one of 5 Restricted-tier items in the Prisma Case, out of 17 items total.

This is one of 24 MP5-SD skins currently listed on the site, spanning multiple rarity tiers.
