The best 50 caliber ammo box depends on whether you prioritize a water-resistant plastic design, a metal container, or several matching cans for organized storage. The MTM AC50C-40 is best for buyers who want a plastic can with a dual latch and O-ring seal. The HOMESTEAD six-pack suits buyers building a larger storage system, while the HARDROCK set includes both 50- and 30-caliber cans.

MTM AC50C-40 Ammo Can
This MTM can is a strong choice for buyers who want a reusable plastic container with a sealing design and secure closure. Its military-style 50-caliber size is intended for ammunition and can also hold emergency gear, medical supplies, batteries, food, tools, boating items, or valuables.
The listed features include rugged polypropylene plastic, a tongue-and-groove O-ring seal system, and heavy-duty dual latches. The manufacturer describes the can as water-resistant, and says the dual latches help create a better seal and reduce the likelihood of accidental opening. It is made in the USA, according to the product name.
Best for: Buyers who prefer plastic and want a water-resistant seal with two latches. Choose this if those features matter more than a metal construction. Limitation: The product is described as water-resistant, not waterproof, so do not treat that wording as a guarantee of submersion protection.
MTM AC50C-35 Orange Field Box
The orange MTM AC50C-35 offers the same key listed storage features as the black MTM option in a more visible color. It is a plastic, military-style 50-caliber-size field box with an O-ring seal system and a heavy-duty dual-latching design.
Its stated uses include ammunition, emergency supplies, medical items, batteries, food, tools, boating gear, and valuables. The orange exterior may help distinguish this container from other boxes when organizing supplies by color; the product details do not specify a particular color-coding system.
Best for: Buyers who want MTM’s plastic construction and seal design but prefer an orange container that is easy to identify among stored gear. Limitation: Like the black version, it is described as water-resistant, not waterproof. Choose another option if your requirement depends on a specifically waterproof claim.
Fortress 50 Caliber Metal Ammo Can
The Fortress can is a straightforward option for shoppers seeking a single metal container. Its listed features are airtight storage, a rubber seal, and an easy-to-carry handle. Those details make it a practical comparison point against plastic cans for buyers who prefer metal construction.
Best for: Buyers who need one metal ammo can with a rubber seal and carrying handle, without a multi-can bundle. The product description is brief, so it does not provide the same detail about latch design, stacking, or alternate storage uses as some other options.
Limitation: The listing calls the can airtight but does not provide further sealing test details in the supplied features. Compare the seller’s current specifications if a particular level of moisture protection is essential.
HOMESTEAD Six-Pack Metal Ammo Cans
This HOMESTEAD option is a six-pack of matching 50-caliber metal cans in desert tan. The listed construction includes heavy-duty steel, reinforced hinges, a double-latched lid, a powder-coat finish, and a rubber seal. The seller describes the containers as airtight and water-tight and says each can is individually tested.
Best for: Buyers who need several matching cans for separating and organizing ammunition, documents, or gear. The listing also describes the cans as stackable, making the set relevant for garage, safe, or cabinet storage where orderly stacking is useful.
Limitation: A six-pack may be more than a buyer needs when only one container is required. The listing’s strong seal claims are seller-provided; check the current product details for handling and storage guidance.
HARDROCK Metal Ammo Can Set
The HARDROCK set includes one 50-caliber can and one smaller 30-caliber can, with the smaller box placed inside the larger one. The listed 50-caliber dimensions are 7.5 by 11.8 by 6.1 inches; the 30-caliber can measures 6.9 by 10.8 by 3.7 inches. Both are described as steel containers.
The product features include a front latch and rubber seal gasket, which the listing says provide a dust-tight and watertight seal. Best for: Buyers who want two sizes for sorting supplies or who value a smaller can that nests inside the larger one for storage.
Limitation: This is not a pair of two 50-caliber cans. Choose a different product if you need matching full-size containers or a multi-pack of the same size.
Buying Guide: How To Choose A 50 Caliber Ammo Box
Should you choose metal or plastic?
Choose a plastic can such as an MTM model if you want polypropylene construction, dual latches, and a stated water-resistant O-ring seal. Consider a metal model if steel construction or a rubber-sealed lid is your priority. The product descriptions use different seal terms, so compare the exact wording rather than assuming all cans offer equal protection.
How important is the seal?
Check whether the listing says water-resistant, airtight, or watertight. These are the sellers’ descriptions, and they are not interchangeable guarantees. If protection from moisture or dust is important, review the current product instructions and avoid exposing a container to conditions beyond its stated use.
Do you need one can or several?
A single can is suitable when you have a limited storage need. A six-pack can help organize multiple groups of supplies, while the HARDROCK set offers two different sizes rather than two identical 50-caliber cans. Confirm package quantity before ordering.
What else should you check?
Look at the stated dimensions, latch type, handle, material, and whether the cans stack or nest. Consider the storage location and what you plan to keep inside. Store ammunition and other contents responsibly, follow applicable laws, and use the manufacturer’s guidance for safe storage.
