At AG DEFENSE POLYMERS a.s, we design and manufacture polymer cartridge cases using nanostructured polymers developed entirely in-house. We produce lightweight, high-strength cases for 7.62×51 mm NATO, 12.7×99 mm NATO, 40×46 mm, and 105/122/152 mm ammunition. By replacing traditional metal components, we reduce weight, lower costs and simplify logistics while ensuring consistent ballistic performance. Based in the Czech Republic, we turn advanced materials science into deployable products for modern armed forces.
