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.
