Patriot Defense Ammunition is a Veteran Owned-and-Operated brand, serving shooters and strengthening our nation with genuine American ingenuity, so you can be proud of every bullet you fire! Designed for range training and tactical exercises.

DISCLAIMER: These components are sourced from the Lake City Army Ammunition Plant, which means the casings are required to be annealed to meet military specification.
