DIFFUSER FOR POLYMER AMMUNITION CARTRIDGES
The present invention provides a diffuser cup adapted to fit a primer recess in an ammunition cartridge comprising: a diffuser ring sized to fit in a primer recess for an ammunition cartridge comprising a diffuser top surface opposite a diffuser bottom surface, a diffuser aperture positioned through the diffuser top surface and the diffuser bottom surface such that the diffuser aperture can align with a flash hole, and a diffuser neck positioned about the diffuser aperture to extend away from the diffuser top surface, wherein the diffuser neck is sized to fit at least partially through the flash hole; and a cup wall attached to the diffuser ring to extend away from the diffuser bottom surface, wherein the cup wall is configured to frictionally fit a primer and frictionally fit a primer recess.
1 . A diffuser cup adapted to fit a primer recess in an ammunition cartridge comprising:
a diffuser ring sized to fit in a primer recess for an ammunition cartridge comprising
a diffuser top surface opposite a diffuser bottom surface,
a diffuser aperture positioned through the diffuser top surface and the diffuser bottom surface such that the diffuser aperture can align with a flash hole, and
a diffuser neck positioned about the diffuser aperture to extend away from the diffuser top surface, wherein the diffuser neck is sized to fit at least partially through the flash hole; and
a cup wall attached to the diffuser ring to extend away from the diffuser bottom surface, wherein the cup wall is configured to frictionally fit a primer and frictionally fit a primer recess.
2 . The diffuser cup of claim 1 , wherein the diffuser ring comprises a metal, an alloy, a composite or a polymer.
