This military ammo box is extremely high quality; made of all steel with a powder-coated interior and exterior. The rubber gasket that seals the lid is solid rubber to keep the moisture out of your can, while the lock kit pre-installed on your ammo can ensures that your bullets will all stay in one place without worry of misuse or misplacement. We are also the only manufacturer to include 3 desiccant packs with the purchase, so you don't have to worry about buying them elsewhere!
