NERF is a brand of plastic children's guns and weapons produced by the American company HASBRO. These are very successful functional children's weapons that shoot foam darts and or foam balls. With regard to the use intended for children, the pistols are designed in such a way that they are safe and that no injury can occur (the condition is, however, that protective face masks are used). The impact of a child's NERF gun can be slightly felt on the skin, but because the muzzle velocity of the weapon is small and the foam ammunition is made of softened foam, the impact is practically harmless even for children. But it is important to protect your eyes with a protective face mask.

NERF pistols come in several series based on thematic focus. These are the series RIVAL, ELITE, MEGA, MODULUS, ZOMBIE STRIKE, DOOMLANDS, NITRO, REBELLE and others. There are types of weapons available - pistols, rifles, submachine guns, machine guns, crossbows, bows, etc.

Most NERF guns are manual, meaning they do not require batteries to operate. The gun is manually "cocked" and fired when the trigger is pressed. A number of weapons are also automatic or semi-automatic and require batteries to operate, which automatically charge the weapon or fire automatically.

A number of original or non-original accessories can also be purchased for NERF guns. These are various magazines, shields, sights, etc.

NERF guns have recently become popular not only among children, but are becoming increasingly popular among the adult community as well. There are NERF tournaments, NERF battles and other events (either for children or adults) where individual teams fight against each other. The game has clear rules, and using different types of weapons and tactics, teams compete against each other until the final final.
