Create a DIY Nerf Gun Step by Step and Crazy Mods

Nerf Gun

NERF is a registered trademark of toys. It was created by the Parker Brothers company in 1969, based in Minnesota, although it is currently owned by the Hasbro company. Most of these toys are plastic weapons that can launch foam rubber projectiles or rubber arrows that do not hurt and specially designed for children or not so young ...

These types of weapons can be bought and are cheap. But also you can create your own Nerf-type pistol or rifle as here we are going to explain you step by step. Both in one case and another, it will be something cheap, but the good thing about creating one yourself is that you will have greater capacity to modify it to your liking. Many people create them to emulate some weapons from their favorite movies, comic book heroes, etc.

Create your own Nerf gun easy and cheap

Homemade Nerf Gun

Our Nerft type guns are easy to do. You simply need something that generates pressurized air for the launch and little else. Everything you need is cheap and you can easily find it at home, and even use repurposed material. For example, one way to create your easy Nerf gun is to use a regular sprayer from the one you have for plants.

You will only need the head, where it has the trigger. This element, where spray the water For the plants, you must join it to a small plastic tube of about 15 cm that you will use as the barrel of the weapon. The joint must be well sealed so that no air escapes. That will be what creates the pressure to launch the ammunition. By introducing a foam rubber projectile into the barrel, with no air leaks, the pressure will be sufficient for it to be fired at close range.

Keep in mind, that when injecting a small amount of air, it may if you are using a very thick tube, don't even shoot out. Or just move a little or fall. That is why it is better to use tubes when narrower is better, for example 1 cm in diameter and even smaller in the case of the sprayer.

Another option would be to use a syringe to inject the compressed air you need to launch the projectile. In this case, if the syringe is large enough and you push the plunger with force, the projectile will come out with greater speed than the previous case. The only thing, that here you will not have a trigger, but it will be something more uncomfortable to launch. But the procedure would be similar, use the syringe attached to a tube where the projectile is inserted ...

You can also use a spring mechanism. Simply put a spring and a mechanism to contract it inside a tube and a trigger that releases the spring so that it shoots out ...

There is also another alternative that is somewhat more advanced, but that will give you better results. And that's designing and printing the gun or Nerf rifle with the help of a 3D printer. In this site you can find the 3D designs to print them directly, or you can create yours from scratch ...


Nerf Ammo

As for the the projectiles you must use, if they are original, you can find them in stores at a low price, then better. The only thing that you will have to find a suitable tube so that they fit perfectly. By fitting very tightly, they will prevent air leaks and make good use of all the force so that they can be shot out.

But if you want to create them yourself, no problem, you can do it with cork To which you can put a small cap on the tip to make them more aerodynamic and weigh a little more. Remember that they can fit snugly into the tube, but not tight so that the pushing force can't push them out.

And it goes without saying that should be used with care, especially if you have modified it and it has more power than a normal one or you are using different ammunition, because you could hurt or hit someone in the eye ... From here we are not responsible for the consequences.

Bomblet ammunition

Some make a fun addition to your ammo, and that is to put a bomblets or Pop-ItsThose little bags that are usually sold in pyrotechnic stores or at fairs and that contain grains that, when pressed or thrown against the ground, explode. The effect is quite curious and you can even shoot someone (in parts other than the face), since the explosion is very slight and does not do any damage.

Modification possibilities

Another of the best options you have is to buy an original Nerf gun and modify its appearance. This way, you will not have so many problems with the ammunition and the firing mechanism. There are many models and modifications of the most crazy and original.

The craziest models

There are some Nerf weapons of the most peculiar that you are going to love, and from which you can get ideas, here are some examples:

  • Adan Savage has created a pretty cool Nerf gun, like Nerf Longstrike version. What it basically does is put a harder spring than the standard one and that makes it much more powerful. In addition, it also increases the volume of the air chamber, increasing speed and precision.
  • Another of the youtubers, such as the one who calls himself Captain Xavier, has created a Nerf Rival Automatic for lovers of zombie movies. It can fire 20 rounds per second, and it has a capacity of 2000 rounds. The best tool to kick out the "zombies" in your meetings with friends or family ...
