The M9 bayonet bridges rifle mounting and close-quarters use, and here it carries the Gamma Doppler treatment. The finish floats black and silver metallic paints over a marbleizing medium under a candy coat, so no two blades come out the same. Phase 4 is one of the distinct pattern variants collectors sort the run into.
M9 Bayonet (Gamma Doppler Phase 4): design, wear and market
Doppler phases
Doppler and Gamma Doppler are split into phases. Standard Doppler has Phase 1–4 plus the rare Ruby (red), Sapphire (blue) and Black Pearl. Gamma Doppler adds Emerald as its top phase.
The phase is part of the item and changes both the look and the value — Ruby, Sapphire, Emerald and Black Pearl trade well above the numbered phases. On this page the phase is shown in the name and selectable where variants exist.
