Rust, dust and water are no match for the Rustrictor Field/Ammo Box Large. This premium ammo can is infused with Vapor Corrosion Inhibitor to surround contents with 360 degrees of rust-proof protection. While Rustrictor technology protects what’s inside, whatever is outside stays there thanks to a water-resistant O-ring seal and brass-bailed latch. There’s also a top-access compartment for extra storage space in the lid. Use it as an ammo box to hold .50 caliber and shot shells; or turn it into general storage for anything else.
