share on

January 2, 2023

Safes and cabinets are a dime a dozen, but when it comes to gun safe brand names, Stack-On stands out for most. Stack-On has been in the business for over forty years, and they create storage solutions with the outdoorsman in mind. While some people function well with the single weapon lock outs, others require a more substantial solution. 

Depending on what you’re looking for, Stack-On has what you need. Whether you’re shopping with function or fashion in mind, there are a multitude of options out there. A couple of things to look out for is what fits your budget, how many guns you’re looking to store, whether you need the extra space for ammo, and how much space you’re looking to take up. Either way, here are some of the finest Stack-On options available out there. 

Best Stack-On Gun Safes

Stack-On FS-24-MG-C 24-Gun Fire Resistant Safe with Combination Lock

This safe comes ready to hold 24 guns so long as they’re under 54 inches tall. It comes with a dark green finish, and a three number combination lock. The four shelves inside are completely adjustable which makes it perfect for storing ammo or handguns in a more accessible spot. On top of that, it’s fire resistant for up to 30 minutes at 1,400 degrees fahrenheit. It comes in at a hefty 360 pounds, so once you set it down and fill it up, no one will be breaking in and just taking it away. 

It also comes with a carpeted interior which will help keep your guns from shifting inside. The one downside with this unit is the fact that once you fill it to capacity with guns, there is no designated space for storage of ammo or anything else. Once the space is filled, that’s it. No other options. But for the price, you can’t go wrong.

Unlike our previous entry, this one gives you the options of designating space for what you need. While the previous safe was specifically built with 24 guns in mind, this safe gives you the option of interchanging the other side from shelf storage to gun storage. With this safe, you have the option of holding 16 guns on one side and storing ammo and other assorted things on the other side. If you need more space for guns then the other side can be converted to fit 15 more making it 31 guns in storage. 

It also comes with a three point locking system that helps it stay in place, so you don’t have to worry about it toppling over at any time. This safe is not fire resistant however. So, while it might be a secure way to lock up your firearms, it is not resistant to all elements. This safe also comes in at 167 pounds, so it’s not as hefty as other safes, but it’s three point locking system takes care of your usual light safe issues.

For those of you that don’t need that much storage, the GCB-8RTA is a safe that’s more suited towards your needs. The first things you’ll notice with this one is the fact that it’s smaller and black. While this might not be for everyone, it fits in better depending on the situation. If you’re looking for someone that fits in great with the surrounding furniture, the slim, black design might be something that catches your eye. Also, since it’s a smaller design, obviously it will fit fewer guns. 

This safe is designed to hold 8 firearms, and none of those guns should exceed the length of 52”. Assembly is required with this one. It is not fire resistant, but it comes with adjustable shelves and barrel rests to help prevent scratching. It also comes with predrilled holes to help secure it, and it is designed to be tamper resistant.

For those of you that are looking for even more compact styles, the in-wall cabinet is perfect as it fits right into a standard 16” on stud walls. It comes with a standard three point locking system, and it also comes with two removable shelves, a hanging key rack, key tags, and collapsible organizer. This is definitely a more inconspicuous design, and it comes in at a light 16 pounds. 

It isn’t fireproof or waterproof, but it definitely serves its purpose. Small safes like this are designed with compactness and stealth in mind. It is designed to hold 2 handguns along with ammo, and it is easily hidden away if you’re looking to keep it from prying eyes.

This little cabinet is 15”, and it’s designed to be secured on top of Stack-On assembled 10 gun cabinets or Stack-On ready to assemble 8 gun cabinets. It fits handguns quite nicely, and it’s the perfect storage for extra ammo if you’re looking to add it on top of your existing cabinets. There’s a removable foam padded bottom, and it is secured by a double-bitted key lock. It comes with all of the equipment to fasten to other safes and also secure itself. 

Ideally, this is a good safe to keep in your closet or on a designated shelf in your dresser. Or if you ended up getting one of the mentioned long firearm safes, this is the perfect design to hold ammo for those that wish to lock ammo apart from the firearms. 

10 Gun Double Door Security Cabinet

I’m always going to be impartial to the double door design. I love the idea of having all of my equipment stored apart from each other, but I don’t like the idea of having to buy more safes or cabinets to create the space to do so. That’s why there are double door cabinets. This one in particular is the perfect middle ground when it comes to size too. It’s a modest design that is built to hold 10 long firearms, but depending on how you handle it, it has a capacity for 24 long firearms. 

It comes with four removable shelves, and both sides are locked separately by a double bitted key lock. It has molded barrel rests with scope standoffs and foam padded sides and shelves. It comes in at a modest 129 pounds, but it also has the bracing system to help keep it from tipping over or being stolen. Sadly, it isn’t fireproof or waterproof, but with everything else that’s included, you’ll be getting every cent worth. Worth a look.

It has just enough space for one handgun, and it’s foam lined bottom is perfect to keep it from being scratched. It comes with an electronic lock that comes with a low battery warning system. Its removable mounting bracket makes it ideal for keeping in the trunk of your vehicle, and at 12 pounds, it’s ideal for those that need to move it around on a regular basis.

Now that we’ve seen some of their best options, there are some questions that many people seem to ask, so we’ll take care of some of them here. Stack-On does give the option to buy extra shelves. So, whether you’ve lost one or just need the extra space, they are available through contacting their customer service. As for a backup key, all of the electronic-lock safes come with backup keys, but if you end up purchasing one of the combination lock safes, you’ll need to make sure to write down your serial number if you plan on contacting customer support to obtain your backup combination. If you plan on getting one of the safes with an electronic lock, you’ll probably want to make sure to change your batteries twice a year at least. Also, don’t forget a dehumidifier.

So there’s our list of the best Stack-On gun safes. I hope there’s something that fits your needs. Also, don’t forget to make sure to research the exact specifications you need personally. Just know that your guns, ammo, and valuables will be safe with the right Stack-On gun safe.
