NERF is a registered trademark for toys. It was created by the Minnesota-based Parker Brothers company in 1969, but is now 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 especially designed for children or not so children .
These kinds of weapons can be bought and are cheap. But you can also create your own Nerf gun or rifle as we will explain here step by step. In both cases, it will be cheap, but the good thing about creating one yourself is that you will have greater ability to modify it to your liking. Many people create them to emulate some weapons from their favorite movies, comic book heroes, etc.
