M9 Bayonet | Gamma Doppler

Origin Story

The M9 Bayonet | Gamma Doppler was introduced on June 16, 2016, as part of the Gamma Exposure update, bringing a distinctive green and black marbleized finish to the game. This high-end knife is known for its "emerald" or "green gem" aesthetic, often compared to other green-hued knives and the original Doppler series. Its visual identity is characterized by deep and bright green tones with darker swirls, achieved through a marbleizing medium and then candy coated. The M9 Bayonet | Gamma Doppler is generally regarded as a status symbol within the community, prized for its flashy in-hand model and the overall prestige of the Gamma Doppler line. Collectors frequently seek out versions with clean, emerald-leaning patterns and very low floats to maximize its gem-like appearance.

Drop Chance

M9 Bayonet | Gamma Doppler is a knife-tier skin, so standard Valve rarity odds don't apply. Knives drop at a combined rate of approximately 0.26% from supported cases before accounting for which knife type and finish you get. Valve doesn't publish individual knife or phase probabilities.

Skin Condition

Float range 0 to 0.08. Exteriors: Factory New, Minimal Wear. StatTrak is available in FN, MW.

• Factory New ($1,800.00): The blade surface is almost fully intact, displaying a rich, glossy green and black marble pattern with minimal to no visible scratches, making the gem-like effect strongest in this condition.
• Minimal Wear (No Recent Price): The overall pattern remains vibrant and mostly intact, but close inspection often reveals small wear marks at the very tip, along the blade edge, or at sharp corners where grayish metal peeks through.

Model

Gamma Doppler uses the legacy M9 Bayonet model, introduced with Gamma Exposure on June 16, 2016. The inspect animation and third-person appearance match the original CS:GO version.

Players can also purchase the M9 Bayonet | Gamma Doppler directly from the Steam Community Market, third-party marketplaces, or various case-opening and skin-trading sites.

Sticker Compatibility

The M9 Bayonet | Gamma Doppler's deep green and black marbleized pattern pairs well with stickers in green, teal, lime, or neon colors, especially those with dark backgrounds. White or silver elements can also provide an effective contrast against the darker handle. As with all knives, there are no sticker slots on the weapon itself, so sticker compatibility focuses on coordinating with other weapon skins in a loadout.
