Metal injection molded primer insert for polymer ammunition
The present invention provides an injection molded primer insert for polymer ammunition comprising: a top surface opposite a bottom surface; a primer flash hole aperture positioned in the top surface extending through to the bottom surface; a substantially cylindrical coupling element extending away from the bottom surface forming an interior surface inside the substantially cylindrical coupling element and an exterior surface; a primer recess in the top surface that extends toward the bottom surface, a primer flash aperture positioned in the primer recess to extend through the bottom surface, and a flange that extends circumferentially about an outer edge of the top surface, wherein the flange is adapted to receive a polymer overmolding.
