Glock-18 | Gamma Doppler Phase 4 (Factory New)

The Glock-18 | Gamma Doppler Phase 4 (Factory New) is a Covert pistol finish — Doppler in green rather than blue, with black-and-green metallic marble worked across the slide in its Phase 4 arrangement. Factory New is the top grade, presenting that candy-coated green at its richest and most mirror-like.

Design

Gamma Doppler is built by swirling black and silver metallic paints through a marbleizing medium and finishing them under a candy coat, which turns out green-and-black where the original Doppler is blue. Phase 4 has its own distribution of that swirl, setting the green against the dark base in a pattern unique to the phase, glinting as the pistol catches the light.

Glock-18 | Gamma Doppler Phase 4 (Factory New) Float and Wear

The finish rolls across a 0.00–0.50 float range, and Factory New sits at the very bottom of it. At this grade the candy gloss is spotless and the green marble reaches full saturation, throwing back light with nothing to interrupt the surface. It's the grade to reach for when you want the Phase 4 pattern showing at its most vivid.

Glock-18 | Gamma Doppler Phase 4 Rarity

Rarity: Covert — the red tier, the highest grade a standard weapon skin reaches. The Covert slots in its collection drop at roughly 0.64% (a rate the tier shares), so any Gamma Doppler Glock is an uncommon pull no matter which phase it lands on.

Glock-18 | Gamma Doppler Phase 4 Case and Collection

This finish is part of The 2021 Train Collection, introduced with Operation Riptide in September 2021. It wasn't sold in a weapon case — copies dropped from the collection during the operation — and with Riptide long over, supply is fixed, so buyers turn to the market rather than unboxing to land one.

Glock-18 | Gamma Doppler Phase 4 Patterns

Gamma Doppler is issued in several phases — Phase 1 through Phase 4 plus the rare Emerald — and the phase sets how the green and black marble is arranged. This one is Phase 4, with its own signature swirl. Because the phase shapes the look, buyers choose it deliberately, and Skin.Land lets you filter listings by phase to secure the Phase 4 pattern specifically.

StatTrak & Souvenir

This finish exists as a regular skin only — no StatTrak edition and no Souvenir version. StatTrak weapons are made solely as alternate case unboxings, and this Gamma Doppler came through a collection instead of a case, so no counter model was ever produced. Souvenir copies come only from Major-tournament packages, and this finish was never part of one.

Glock-18 | Gamma Doppler Phase 4 Price

Factory New tops the Phase 4 ladder as the most expensive grade, a premium Covert pickup for a Glock. Phase 4 prices below the grail Emerald while holding its own among the numbered phases. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What is Gamma Doppler Phase 4?

It's one arrangement of the Gamma Doppler finish, the green counterpart to Doppler. The skin relies on the same marbleizing-and-candy-coat technique but renders in green and black, and Phase 4 denotes one specific way that green-and-black marble is spread across the Glock's slide.

Is Factory New worth it for Phase 4?

If you want the pattern at its best, yes. Factory New shows the candy-coated green at peak gloss and saturation with no wear on the surface. It's the top-priced grade, but on a marble finish the flawless reflection is much of what the price buys you.

Which gloves match Gamma Doppler Phase 4?

The green-and-black marble suits a green or dark loadout. Green gloves echo the marble directly, while black or gunmetal wraps let the green stand out as the loudest color on your hands. Adding other green accents across your knife pulls the whole build into a unified green theme.
