Molded out of rugged polypropylene plastic, this comfortably-handled ammo can will hold up to some pretty harsh treatment. MTM's Plastic 50 caliber can with rounded corners is designed to fit the same amount of bulk ammo storage as the original and will not rust. A heavy-duty dual latching system makes for a better seal that is less likely to open accidentally while the tongue and groove O-Ring seal system make it water-resistant. The double padlock tabs along with molded-in stacking ridges make these forest green containers the perfect solution to so many storage needs.
