An airgun is a type of firearm that uses compressed air or gas to propel projectiles, typically pellets or BBs. Unlike traditional firearms that rely on gunpowder, airguns are quieter and often used for target shooting, pest control, and small game hunting. They come in various types, including pneumatic, spring-powered, and CO2-powered models. Airguns are popular for recreational shooting and training due to their lower cost and reduced noise levels. They are available in different calibers, with .177 and .22 being the most common. Safety is essential when using airguns, as they can still cause injury if misused.
