The ★ M9 Bayonet | Gamma Doppler is a Covert knife skin in Counter-Strike 2, available since June 2016 from the Gamma Case. This is the Phase 1 phase of the finish, distinguished by its specific colourway.

The float range for this finish is restricted to 0.00–0.08, so Factory New and Minimal Wear are the only obtainable conditions on the open market. Battle-Scarred examples are not produced, so the most worn copies still retain a relatively clean appearance.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for ★ M9 Bayonet | Gamma Doppler are tracked across 10 marketplaces, with prices spanning $1,243 to $1,747 depending on wear, variant, and seller.
