The 10 Best Ammo Cans

Updated by Ezvid Wiki Editors · How we research

The top 5 ammo cans: Ammo Can Man M2A1, MTM AC50C, Sheffield 12629, Fortress 50AM and MTM AC4C

Military steel cans, plastic boxes and range crates, compared by seal, latches, weight and locks. The U.S.-made Ammo Can Man M2A1 leads the field. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.

The classic steel ammo can is built to a U.S. military spec, and the rubber gasket in its lid does the real work of keeping cartridges dry. Plastic copies are lighter and never rust, but most only resist splashes. This list covers both, plus crates and pistol boxes, for shooters storing ammo at home or hauling it to the range.

Editor's Notes

November 1, 2026, by Ezvid Wiki Editors:

A U.S.-made steel can with a good gasket is still the surest way to keep ammo dry, so the Ammo Can Man M2A1 now leads. It replaces the older surplus M2A1 listing with the same military can from the same supplier. The MTM AC50C joins as the plastic pick, and the Fortress 50AM and Fortress 30AM cover buyers who want fresh steel cans in either size.

The WaterBrick Stackable and the standalone MTM AC30T dropped out because of availability concerns. The AC30T still comes four to a crate in the MTM AC4C, which stays, and the WaterBrick container is now a special honor. Blackhawk's 30 caliber can no longer turns up for sale, and the Solid Tactical Premium is an imported copy that costs more than the real thing.

Ammo cans don't get lab tests. We worked from the military box specification, MTM's own notes on which cans can go underwater, an ammunition seller's dunk and stacking trials and owner reports of leaks and rust.

Earlier notes

June 18, 2021, by Christopher Thomas:

We've updated our top choice to the Plano 1312. To be clear, you don't have to spend a fortune on a good ammo can, which is why the Plano is still generally the best. If you want something just a bit more high-end, the Solid Tactical Premium is a great choice. It also comes in a variety of colors in addition to two widths. The only completely new addition to this iteration of the Wiki is the MTM Case-Gard P-100, which is the perfect accompaniment to a day of handgun fun at the range. None of our other picks have been altered recently.

A sturdy ammo can is a must for maintaining the integrity of your ammunition, and we have here kept choices in both metal and plastic that can do just that. In the former category, the Sportsman Series ABox Men's Army Style is a simple, but effective, choice for most; the Blackhawk! 30 Caliber is one to consider, as well, although it isn't terribly large. And, of course, there's always the U.S. Military Surplus M2A1, which offers an authentic feel for everything from storage to decoration. Note, though, that the stenciling on each individual box can vary.

Those who are interested in plastic items might consider the popular Plano Molding Tactical Custom or, for beefier needs, the MTM AC4C. The latter provides plenty of storage space and includes a crate with tie-down attachment points for your peace of mind. Finally, we added one slightly expensive choice, the Pelican Vault V250. It's incredibly rugged, and it has an ergonomic handle for comfortable transport. It won't let dust in, and can't be crushed easily, so you might even consider it for stashing some survival food or gear.

Special Honors

SecureIt Ammo Cabinets If a few cans have turned into a closet full, SecureIt, a gun storage maker, sells steel cabinets built for ammo and gear. Its modular line includes a compact drawer cabinet that bolts into the same system as its gun safes, and its military-style cabinets add shelves for bulk cans. They cost far more than any can here, but they lock and keep everything in one place. secureitgunstorage.com

WaterBrick AmmoBrick The AmmoBrick comes from the maker of WaterBrick stackable water containers. It's a squat, stackable plastic box that locks into its siblings, so ammo, water and food can share one tidy stack in an emergency kit. Retail stock comes and goes, so check the maker's own store first. waterbrick.org

Steel Or Plastic

Clamped down by its latch, that gasket keeps out water and air, which is why surplus cans have long been the default for long-term storage.

The olive steel can most people picture is the M2A1, a .50-caliber box built to the U.S. military specification MIL-DTL-3060, with a rubber gasket inside the hinged lid (Wikipedia: Ammunition box). Clamped down by its latch, that gasket keeps out water and air, which is why surplus cans have long been the default for long-term storage. Steel also stands up to crushing. The costs are weight, about five or six pounds empty, and rust wherever the paint gets chipped.

Plastic cans copy the shape in polypropylene. They weigh a pound or two, never rust and often come with padlock tabs, but most are water resistant rather than waterproof. MTM, which makes a large share of them in Ohio, describes its AC50C as sealed against water and dust with an O-ring yet not submersible (MTM: AC50C). For a basement shelf or a dry closet, plastic is fine. For a boat, a flood-prone garage or a can that rides in an open truck bed, steel with a healthy gasket is the safer bet.

Sizes: .30, .50 And Fat 50

Military can names come from the ammunition they first carried, not from what you'll put in them. A .30 caliber can is the narrow one, about 11 inches long, 3.75 inches wide and 7 inches tall. A .50 caliber can is the same length and height but about 5.5 inches wide, so it holds roughly half again as much and stands steadier. The PA108, or fat 50, is taller and wider still; surplus dealers such as Ammo Can Man sell it for bulk boxes.

How many rounds fit depends on the caliber and how they're packed, so treat round counts on sales pages as rough. Slim .30-size cans also tip over more easily. MTM says as much about its own small cans and sells the AC4C crate to hold four of them upright with tie-down slots. For pistol ammo that comes loose or in flimsy boxes, a flip-top case with one slot per round keeps cartridges from scuffing, then goes inside a sealed can for storage.

Keeping Ammo Dry, Locked And Legal

A gasket only works when it's in good shape and pressed evenly. An ammunition retailer's informal trials found that heavy weight stacked on steel cans can flatten the gasket and break the seal, so stack cans in their crates or keep the pile light (Ammunition To Go: M2A1 vs M2A2). The same seller dunked imported and U.S.-made cans for hours and found the imported can sealed fine, though it rated U.S. cans tougher overall (Ammunition To Go: American vs imported cans). Check any new can's gasket for gaps, and toss in a desiccant pack if the can will sit for months.

An ammo can is not a safe. Padlock tabs and latch holes stop curious hands, not a determined thief, so store cans where children can't reach them, ideally in a locked cabinet. Storage and transport rules vary by state and city, so check your local law, and see the NSSF's safety resources for storage basics.

How we researched this

We compared 18 ammo cans, crates and pistol boxes, read the makers' product pages and the military specification behind the M2A1, reviewed an ammunition retailer's informal seal and stacking trials, looked at long-term owner feedback on leaks, rust and latches, and checked every brand for recalls with the U.S. Consumer Product Safety Commission.

Frequently asked questions

Are ammo cans necessary?

Not strictly. Ammunition kept in a cool, dry room lasts a long time in its original boxes. A sealed can with a desiccant pack is cheap insurance against humidity, leaks and spills, and it makes ammo easier to carry and sort.

What's the difference between a .30 and a .50 caliber ammo can?

Width. Both are about 11 inches long and 7 inches tall, but the .30 can is about 3.75 inches wide and the .50 about 5.5 inches, so the .50 holds more and tips over less. The names come from the military ammo they first carried; either holds any caliber that fits.

Are American-made ammo cans better than imported ones?

U.S.-made military cans are built to a published spec, and they're generally judged tougher. Informal dunk tests by an ammunition retailer found a well-made imported can sealed fine, though. Whatever you buy, check that the gasket is seated evenly and has no gaps.

Are plastic ammo cans waterproof?

Most aren't. Plastic cans with O-rings keep out dust and rain, but makers such as MTM say they aren't meant to go underwater. For a boat or a flood-prone spot, choose steel with a good gasket.

Can you lock an ammo can?

Yes. Most plastic cans have padlock tabs, and steel cans have a latch hole that takes a small padlock. A lock keeps out children and casual snoops, but a can is easy to carry off, so keep it in a locked cabinet or safe if theft is a concern.
