M249 | System Lock

M249 | System Lock released January 8, 2015 as part of the Chroma 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 Mil-Spec Grade finish, with both a StatTrak™ and a Souvenir edition.

As a finish, "System Lock" is applied to the M249 — a light machine gun with a massive magazine, offering suppressing fire at the cost of mobility — and carries the blue rarity color every Mil-Spec Grade skin shares on the Steam Market and in-game.

That Mil-Spec Grade classification places it at the base of the tiers a Case can drop — the most common outcome of opening the Case(s) it comes from.

M249 | System Lock ships in all five wear conditions, but its float is capped between 0.00 and 0.80 — 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.

M249 | System Lock comes from the Chroma 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 Mil-Spec Grade pull like this one at roughly 1 in 6 (15.9840%).

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 Mil-Spec Grade finish, M249 | System Lock sits among the more common pulls from the Chroma Case rather than being a chase item — a straightforward, affordable way to add a M249 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.

M249 | System Lock has been part of the Chroma Case since January 8, 2015, 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 Mil-Spec Grade items in the Chroma Case, out of 14 items total.

This is one of 26 M249 skins currently listed on the site, spanning multiple rarity tiers.
