My Life-Size Cardboard AA-12 Shotgun with Drum Mag

I was inspired to create a cardboard AA-12 shotgun because its one of the most powerful shotguns I’ve had fun using in videogames like Grand Theft Auto 4. I’ve always thought it looked intense and cool. After finishing my first cardboard sniper rifle, I knew I wanted to take things further, so I chose the AA-12 as my next challenge. Using around 5 to 6 layers of cardboard, I tried to match its size and shape as close as I could. What made this build even more special was that some of the cardboard I used came from a Minecraft Warden cosplay I made for Halloween. Reusing old painted material gave it a unique texture and look. This build helped push my skills forward—and it’s one of the most fun cardboard gun projects I’ve done so far.

How I Built My Cardboard AA-12 Shotgun

Building the Base

Figuring out the exact size of the cardboard AA-12 shotgun was one of the hardest parts of this build. I started by looking up references online and sketching out the shape of the shotgun by hand. Then, I carefully cut out the parts using a craft blade and stacked around 5 or 6 layers of cardboard to give the gun a solid, thick feel. Each layer had to be glued tightly so the shape would hold together and look right from all angles. Even though it took a lot of patience, this layering technique really helped bring the build to life.

Adding The Shell Feature

I wanted to do something a little different with my cardboard AA-12 build, so I came up with the idea of adding a custom shell slot. I cut out a rectangular hole in the side of the AA-12’s body, big enough to insert a handmade cardboard shotgun shell. I imagined it as an explosive round for extra detail. Even though it’s not functional, it gave the build a cool extra touch and made it stand out from a regular flat design.

Crafting the Cardboard Drum Mag

I knew from the start that crafting a cardboard AA-12 with a drum mag was mandatory, since the drum magazine is one of the most iconic features of the shotgun. To make it, I cut out two thick cardboard circles and used a curved strip of cardboard to form the outer wall of the drum. Building it was a fun part of the process, but the tricky part came when I realized it would fall out too easily unless I kept it fixed in place. While the mag doesn’t come out, it still fits snugly and adds a ton of realism to the overall look of the shotgun.

Adding The Barrel and Sight

Compared to the other parts of the shotgun, the barrel and sight were actually pretty easy to build. Since the AA-12 has a short barrel, I didn’t have to worry too much about keeping it perfectly straight. I focused more on making sure the front section looked sturdy and matched the reference pictures I found. I also added a simple aiming section on top to finish it off and give it a clean, tactical look.

The End Result

Considering I was around 13 years old when I made this cardboard AA-12 shotgun, I’m proud of how creative I was with the build. It feels pretty close to the real AA-12, especially for one of my early projects. In the future, I’d love to figure out how to make the cardboard drum mag removable to make it even more realistic. It would be really cool to see how a new cardboard AA-12 turns out now that my crafting skills have improved.
