MTM ammo cans are a great way to store bulk or boxed ammo. Its all plastic design is lighter in weight than the 50 caliber US Military Surplus Ammo Can. Transferring ammo to and from the range, just became a little easier and they are ideal for ammo storage. Molded out of rugged polypropylene plastic, these comfortably handled ammo cans will hold up to some pretty harsh treatment. Utilizing MTM's tongue and groove O-Ring seal system for a superior water-resistant seal, these cans are designed to fit the included ammo boxes perfectly. A heavy-duty dual latching system makes for a better seal and less likely to open accidentally. Double padlock tabs along with molded-in stacking ridges, make these solid containers the perfect solution to so many storage needs.
