What are the best ammo safes?

After researching every variety of ammo safe from the major manufacturers and Amazon, testing more than a dozen, including testing room for loose ammo, ammunition boxes, handguns, and a few firearm accessories, we recommend the SentrySafe SFW123GDC Fireproof/Waterproof Safe as the best ammo safe you can get for your home or office.

The SentrySafe SFW123GDC Fireproof/Waterproof Safe is independently verified by the safety organization UL to store and protect your ammo and other items during a fire for up to a full hour with heat up to 1,700 °F.


  • Measurements: 16.3 in. W x 19.3 in. D x 17.8 in. H
  • Weight: 87 pounds
  • UL fire rating: 1 hour at 1,700 °F

What we liked:

What we didn't:

SentrySafe also rates the SFW123GDC as waterproof when submerged in up to 8” of water for 24 hours.

At 1.23 cubic feet of storage, it easily met our minimum size threshold for effective ammunition storage (we wanted at least 1 square foot of storage), which is large enough to 2,000+ rounds of ammo, a few accessories, and a gun count of 1-2 handguns. 

Drop rated as well

The additional protection also comes in the form of 15 foot ETL Verified drop protection.

This means that if the safe is on the second floor and it burns through in a fire, the safe is verified to maintain its integrity even if it falls through the floor. The perma shelves should stay put even with the jolt of falling from one floor to the other.  

Heavy & feature-rich

These features make the SentrySafe more than worth the price – as it’s one of the most expensive of our ammo safe recommendations.

That said, the SFW123GDC is a quality product – it’s noticeably heavier than many other ammo safes of similar capacities—it weighs 87 pounds—and takes up about the same amount of floor space as a large mini-fridge.

It also offers nice safe-level features like a solid steel construction, no external hinges, a pry-resistant hinge bar, locking drawer, interior light, 4 bolt locking mechanism, and bolt down hardware.

We liked it enough to consider it a decent gun safe as well.

In our opinion, the extra weight coupled with the fire and water-resistant features make it well worth it because it maximizes the chance your items will survive a disaster or determined thief.

Best Budget Ammo Safe:

AmazonBasics Home Keypad Safe
  • 1.52-cubic-foot home safe for storing important documents, jewelry, and other valuables
  • Programmable electronic keypad ensures secure, easy operation; back-up key for emergency use; AA...
  • Heavy-duty carbon-steel construction (8-gauge steel door and 14-gauge steel body); 2 live-door bolts...

The AmazonBasics Home Keypad Safe is the best option if you’re limited to $100 or less on an ammo safe, don’t have a need for a biometric entry, and aren’t interested in a UL rating for fire resistance.


  • Measurements: 13.8 by 13 by 16.5 inches
  • Weight: 37 pounds
  • UL fireproof rating: None

What we liked:

What we didn't:

Lots of storage space for little investment

Its main advantage beyond price is it packs a lot of storage space into a small package – giving you 1.5 cubic feet of storage in a smaller package than our top recommendation, the SentrySafe. you have limited floor space. It’s also considerably lighter than the SentrySafe at just 37 pounds, making it easier to move if necessary.

We also like that it has all the same entry mechanisms as our top pick (both a digital keypad and physical key) so you’re not sacrificing entry options with this choice.

Best Ammo Storage Cabinet:

Stack-On GCB-900 Steel Pistol/Ammo Cabinet, Black
  • The Stack-On Pistol/Ammo security cabinet is ideal for holding pistols, Ammo, supplies and valuables
  • A locking mechanism passes through the steel door and is secured behind the frame for added...
  • The unit is fully lockable with a key coded, double-bitted lock

If you need to store ammo securely, are looking for the simplest storage option (a basic keyed ammo cabinet) and don’t want to spend more than $100, the Stack-On GCB-900 Steel Ammo Cabinet is a good choice.


  • Measurements: 10 x 18 x 21 inches
  • Weight: 25 pounds
  • UL fire rating: None

What we liked:

What we didn't:

Plenty of storage & features

It’s no rifle cabinet at 1.8 cubic-foot capacity, but it’s the larger version of our runner-up ammo cabinet pick (also a Stock-On – the smaller GCB-500 cabinet) and designed to hold ammo, handguns, optics, grip replacements, spare magazines, and accessories safely.

We really liked how it has 2 separate internal shelves, which create 3 different compartments. Most safes in this size range have a single shelf and 2 compartments, so the additional compartment helps with organization.

Flaws worth noting

It lacks the kinds of features you’d find with an actual ammo safe – things like a UL fireproof rating, locking door bolts, a digital keypad, & thinker, more durable exterior steel construction.

Compared with the SentrySafe, the is not rated for any length of time in a fire, but it’s still an easy way to safely keep your ammunition and associated firearms safe from prying eyes.

It’s also much lighter than a true safe at 25 pounds—making it easier to move around—and less considerably expensive.

Best Budget Ammo Cabinet:

Stack-On GCB-500 Steel Pistol/Ammo Cabinet, Black
  • Perfect for holding pistols, ammo, supplies and valuables.
  • Locking mechanism passes through steel door and is secured behind the steel door frame for added...
  • Pre-drilled mounting holes allow for easy attachment to floor, ceiling, wall or other Stack-On...

The smaller sibling to our top ammo storage cabinet recommendation, the Stack-On GCB-500 is smaller, lighter, and less expensive. 

If you’re looking for the minimum possible investment for storing ammunition safely the GCB-500 offers the best mix of purpose-driven ammo cabinet design and budget-friendliness.


  • Measurements: 17 W x 10 D x 15 H
  • Weight: 20 pounds
  • UL fire rating: None

What we liked:

What we didn't:

This ammo safe is the same depth as the GCB-900, but 4 inches narrower and 3 inches shorter, so if you have limited space available this could also be a solid choice.

Due to the GCB-500’s shorter stature, this cabinet has just a single shelf, and 2 compartments – but for less than $70 it’s really the lowest possible bar to a quality ammo cabinet.

Best Biometric Ammo Safe:

BARSKA Large Biometric Safe, Multi (AX11650)
  • 【High-Quality Secure Safe】BARSKA Biometric Safe is the ultimate in quick access security...
  • 【Advanced Biometric Scanner】Our top-quality biometric scanner allows access to your valuables in...
  • 【Ultra-Compact Storage】With 1.45 ft3 and 2 removable shelves, the Biometric Safe has all the...

The BARSKA Large Biometric Safe is a good alternative if you really want the speed of biometric access (or our top pick is out of stock).


  • Measurements: 14 x 13 x 20
  • Weight: 44 pounds
  • UL fireproof rating: None

What we liked:

What we didn't:

The biometric entry makes access quick & easy.

The biometric entry is great if you’re like us and seem to be great at losing keys – plus, it’s the best option of child-safety is a top concern as the fingerprint reader is basically foolproof and programmable with multiple fingerprints so that you can provide access to a trusted loved one.

It was also the second-heaviest safe we tested, at 44 pounds, so it’s certainly not something most folks would run off with.

Not cheap but worth the investment

It’s not going to be helpful if you are on a tighter budget (it generally retails for as much if not more than our top pick), but if you have less floor space, the BARSKA might be one to consider as it’s slightly smaller than the SentrySafe in terms of footprint.

Not UL rated but sturdy & well-made

The BARSKA is not UL certified like our main pick, the SentrySafe, so given the price, that might matter to some buyers. It is also not waterproof, but even if it doesn’t survive a flood, the safe should at least keep out moisture from basements or other damp areas.

Best Ammo Box:

MTM ACR5-72 ACR5 Ammo Crate Utility Box, Brown, Medium
  • Included Components: Ammo Can
  • Material Type: Polypropylene

If you’re less concerned about security and fancy features like biometric entry mechanisms and are more interested in straightforward ammo storage that’s easy to move around, check out the MTM ACR5 Ammo Crate.

It’s designed to store ammo safely and has a stackable design that allows you to compartmentalize your ammunition by whatever criteria make sense.


  • Measurements: 19″ x 15.75″ x 5.25″
  • Weight: 2 pounds
  • UL fireproof rating: None

What we liked:

What we didn't:

Thousands of rounds of ammo in one box

In our tests, each crate accommodated about 2,000 rounds of 7.62 ammo – so you should be able to get 2,500 rounds of rimfire ammo, and possibly less with larger bore rounds.

Designed for mobility

The crates have 2 side handles that make moving them around easy – even when loaded with ammo and gear.

They also have a water-resistant rubber gasket that runs the lip of the crate, while not submersible, will keep things dry in a variety of environments, so storing ammo in one, dry goods in another, and survival-oriented stuff in a 3rd crate makes for mobile survival unit that’s stable and convenient.

Subtle safety features

Even if it doesn’t have an actual locking mechanism, the ACR5 isn’t devoid of safety/security features. There are padlock tabs on either side of the crate body so that you can lock them up securely (even though the polypropylene wouldn’t take much to get through with a hacksaw).

There are also 4 tie-down points to cinch the box to your truck or motorcycle and keep in place for travel.

Priced right

The best part is the price – they’re about $15 each—a fantastic price for something so durable and purpose-built for ammo containment.

Best Hidden/Wall Ammo Safe:

Viking Security Safe VS-52BLX Biometric Fingerprint Hidden Wall Safe
  • EASY TO SET UP & SIMPLE TO USE - Scan & Save up to 32 Fingerprints for Multiple People or 1 PIN...


  • Measurements: 19” x 14” x 4”
  • Weight: 37 pounds
  • UL fireproof rating: None

What we liked:

What we didn't:

If you’re interested in concealing your ammo & smaller firearms with a wall-mounted safe, we recommend the Viking Security Safe VS-52BLX. It’s designed to fit snugly between wall studs and offers a biometric scanner for quick access to its contents. It also offers a digital keypad and physical key with multiple entry mechanisms. 

We liked the Viking Security Safe, in addition to the biometric scanner, the 3.5” internal depth. Most wall-mounted safes offer less than 3” of depth, which can make storing boxes of ammo or handguns difficult. The VS-52BLX is deeper than other ammo safes, which opens up lots of storage options.

We also appreciated the range of features this safe offered for the price – an interior LED light, 3 separate shelves and 4 compartments, a carpeted interior to prevent dings, and key hooks on the door – a natural spot for backup keys.

It doesn’t fit 100% flush to the wall, but the small bulge from the fingerprint reader is more than worth the speed of entry and additional room for storage.


Each of these ammo safes offer a different set of benefits, but our top pick is the SentrySafe SFW123GDC Fireproof/Waterproof Safe. We loved that it’s independently verified by UL for up to a full hour with heat up to 1,700 °F. It touched on all the important criteria for an ammo safe:

  • Quality build
  • Reliable entry systems
  • Multiple entry mechanisms
