It is not required by law to have a suppressor on an airsoft gun, but it is highly recommended. Many airsoft guns produce high levels of noise, and a suppressor can drastically reduce the sound. This is important for two reasons: safety and stealth.
For safety, players must be able to hear when someone is coming so they can take cover. A suppressor greatly reduces the noise level, making it difficult to hear someone coming. For stealth, people playing airsoft mustn’t give away their position by making too much noise. A suppressor will help keep your location hidden.
