Want to build a dream gun wall or gun storage, but you don't have the storage space for a full gun room? Consider making a custom gun closet storage display!
A gun rack or storage wall in your closet is a great solution for firearm storage! Many gun owners don't realize that you can build a custom firearm storage solution in most home closets, and with a few modifications, it can be just as safe as a gun cabinet, with the added benefit of being hidden in plain sight. You don't need a vault door or panic room to safely store your gun collection like you see in the movies!
You don't need to build a safe room to mount your awesome collection. You can easily build a custom gun rack for your closet no matter how small your home is. This is a great solution for safe, easy access storage, and it looks great too!
Below you will find a step-by-step guide for building your own closet door gun rack!
Closet gun storage allows you to build a custom solution into a space in your home without having to invest in a gun safe or gun cabinet. You even have the option of turning your closet into a secret door for added security!
Storage in your closet is also a great way to keep your guns from getting damaged and help keep your firearms safe and secure from unauthorized access to them.
Building custom gun storage in your closet is easy!
Step 1. Determine The Size and Location
First, to make a homemade gun rack, you need to decide where the gun rack will go. You can put your firearm storage on the back of the door, on the back wall using wall-mounted gun racks, or even build a custom slide-out panel. If you have a larger walk-in closet, you could even build a larger horizontal gun rack with additional vertical storage next to it.
Our closet doesn't have a lot of space so we chose to build ours on the back of the closet door for maximum use of the space.
If you happen to have a basement closet with concrete walls, this is an even more secure location that could be the best place for your pistols and long guns.
Step 2. Find a Design You Like
Next, you need to choose how you will build your gun storage. A simple option would be to mount your Spartan Mounts directly to the drywall inside the closet.
Another option would be to build a custom plywood panel or grid panels that you can screw your rifle mounts and pistol mounts to.
We chose to invest in Slatwall so that we could move the firearms and magazines in the future as our setup changes.
Step 3. Gather the Supplies
To build our closet door gun wall, we used the following:
 50"x1"x1/8" Cold Rolled Steel Bar (Find at hardware store or local metal supplier)
Common tools: Drill, saw, screwdriver, allen set, Sharpie, tape measure, hacksaw, grinder or file, double-stick tape
Step 4. Secure the closet
We chose to add some security features to keep our firearms secure in the closet. We chose to add the biometric doorknob linked above for quick access. If you don't trust the fingerprint locks, you can choose a standard lock or a digital keypad lock for peace of mind.
Because our hinge-pins are on the outside of the door, it is also a good idea to swap out the hinges for ones with non-removable pins to create a more secured door.
These changes won't make the closet into a gun safe, but will make it at least as secure as a standard gun cabinet. If you want to go even further, consider installing a more secure door, false wall panel, a secondary locking mechanism, or even a small motion detector and alarm system. It is all up to personal preferences how far you want to go with your project!
Step 5. Build The Structure
The first thing we did was to install the L-brackets to the steel bars. This was simply done by marking the hole locations, and drilling and tapping the bars to receive the 10-24 screws. Make sure you add some washers for a better grip.
For the slatwall build on the back of a closet door, we used a table saw to cut one of the panels in half. If you don't have a table saw, you could use a circular saw, or even a hand saw.
Once cut, mark and drill 9 holes on each half-panel, where the screws will be attached to the steel support bars from the first step.
After carefully lining the two half-panels up, lay the steel bars below the hole locations, and mark where the screws should be drilled in the next step.
Remove the bars. At each marked location, use your drill and tap to thread the holes for the screws. (It's a great idea to add some oil to lubricate the tap!)
Add screws to all 18 holes with fender washers. I chose to spray paint my washers black to match the black screws I was using.
Using a hacksaw or grinder, cut the L-bracket shorter to only have a single screw hole. Use a countersink bit to allow a screw to sit flush in this top mounting hole.
Now that your slatwall closet gun storage is completed, you can mount your Rifles, Shotguns, Pistols, Magazines, Silencers, and anything else you want!
The slatwall is convenient because it allows you to test locations and move them as you expand your collection.
Try locating all your magazines together in one section of the closet display. Alternatively, you can mount matching firearms and their mags together for easier access!
When mounting your firearm collection, consider the environment they will be in. If you are storing them in your basement or against an exterior wall, it would be a good idea to install a safe dehumidifier to keep everything rust free.
