Molded out of rugged polypropylene plastic, this comfortably-handled ammo can will hold up to pretty harsh treatment and at 1.76 lbs., it weighs significantly less that metal military ammo cans. Utilizing MTM's tongue and groove O-Ring seal system for a superior water-resistant seal, the 50 caliber can is designed to carry up to 30 lbs. of ammo or other gear. A heavy-duty dual latching system provides 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 many storage needs. Inside dimensions are 5.8"x11"x7.2".
