This project by [blackfish] shows off a cardboard lookalike of an MP5 that loads from a working magazine, has a functional charging handle, and flings paper projectiles with at least enough accuracy to plink some red party cups. It was made entirely from corrugated cardboard, paper, rubber bands, and toothpicks.
In the video (embedded below) you can see some clever construction techniques. For example, using a cyanoacrylate adhesive to saturate areas of wood, cardboard, or paper to give them added strength and rigidity. The video is well-edited and worth a watch to see the whole process; [blackfish] even uses a peeled piece of cardboard — exposing the corrugated part — as a set of detents (6:56) to retain the magazine.
Cardboard is a great prototyping material, so long as you can work with its characteristics instead of against them, but luckily we have some tips on just how to do just that.

Cardboard is true #hackcycling! Where is the HaD Prize segment for building projects out of the packaging it comes in?!
Once upon a time, there was a self-packaged VR headset made of cardboard. It was called… Cardboard.
If I ever was to break out of prison, this is what I would build.
Question is, why are you there in the first place.
carrying a concealed (cardboard) weapon w/o a permit.
clearly he was in for forging papers
Beautiful use of a pun.
You shouldn’t have your finger on the trigger while one of your hands is near the muzzle…
Treat toy weapons as real ones, and you’ll be less likely to have an accident while handling a real one.
Very nice job! Enough reinforced cardboard and you can model almost anything. Had a cuckoo clock kit once, but never assembled it because way too many parts.

Relax, it’s OK, is wearing a reflective vest…

Have you seen the paper replicas? Check out Jonocade and Tacome1942 on YouTube, they make paper replicas like 1911s and then reload brass with primers-only and wood bullets. They work! Very functionally-accurate and detailed for being overkill paper mache.
in other news schools across america ban paper and cardboard.
Exactly. Good one.
Some student will eventually hack his school’s educational tablets and use a zero-day exploit to crash their power management chip and set the lithium battery to fire. After that it’s just a matter of throwing the tablets around, no paper needed.
Isn’t glue sniffing still a thing?
Keep the cardboard, ban the glue.
Some of them do ban cyanoacrylate and epoxies, because of chemical sensitivitys.
Perfect use of wicking grade super glue to reinforce the cardboard parts.
The sights aren’t even adjustable!
That’s always been the problem with iron sights. Even when they’re cardboard.
I rarely watch entire videos anymore, however this one was worth it. I have another skill to tackle I suppose.
