Air guns are firearms that use compressed air or gas to propel projectiles, typically pellets or BBs. They are often used for target shooting, pest control, and recreational purposes. Unlike traditional firearms, air guns do not rely on gunpowder, making them quieter and often easier to handle. There are two main types of air guns: pneumatic and spring-powered. Pneumatic air guns use compressed air or CO2 cartridges, while spring-powered guns use a coiled spring mechanism. Both types can vary in power and accuracy, making them suitable for different shooting activities and skill levels.
