Airsoft guns use 6mm plastic or biodegradable BBs. The BBs are stored in magazines and propelled out of the barrel by compressed air, springs, or gas. Airsoft guns have lower power than real firearms. Their projectiles travel around 300 feet per second, while real bullets travel over 1,000 feet per second. Airsoft guns usually have orange tips to distinguish them from real firearms. They are used recreationally for target practice, training simulations, and war games similar to paintball. Airsoft guns are not classified as firearms under federal law and have minimal ability to cause injury. However, state and local regulations on them vary. Some areas prohibit airsoft guns or require permits/registration.
Overall, airsoft provides a safer alternative to real firearms for simulation and recreation. Differences in state laws mean users should research if restrictions apply in their area.
