AUG | Steel Sentinel

AUG | Steel Sentinel released March 31, 2025 as part of the Train 2025 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 an Industrial Grade finish, with a Souvenir edition but no StatTrak™ version.

As a finish, "Steel Sentinel" is applied to the AUG — a scoped, semi-automatic rifle available to Counter-Terrorists, effective at range without needing a dedicated sniper rifle — and carries the light blue rarity color every Industrial Grade skin shares on the Steam Market and in-game.

That Industrial 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.

AUG | Steel Sentinel 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.

AUG | Steel Sentinel is part of the Train 2025 Collection rather than being unboxed from a traditional weapon Case — the Collection is not tied to any live drop mechanic, 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 7, 13.3376%) 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 an Industrial Grade finish, AUG | Steel Sentinel sits among the more common pulls from the Train 2025 Collection rather than being a chase item — a straightforward, affordable way to add an AUG 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.

AUG | Steel Sentinel has been part of the Train 2025 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 6 Industrial Grade items in the Train 2025 Collection, out of 16 items total.

This is one of 46 AUG skins currently listed on the site, spanning multiple rarity tiers.
