Pneumatic guns are devices that use compressed air or gas to propel projectiles, such as pellets or BBs. They are commonly used in activities like target shooting, hunting, and pest control. These guns can be powered by various methods, including CO2 cartridges or hand-pumped air, making them versatile for different users. Unlike traditional firearms, pneumatic guns do not rely on gunpowder, which makes them quieter and often easier to handle. They come in various types, including air rifles and air pistols, and are popular for recreational shooting and training due to their lower cost and reduced recoil.
