Air rifles are firearms that use compressed air or gas to propel pellets or BBs. They are often used for target shooting, small game hunting, and pest control. Unlike traditional firearms, air rifles do not use gunpowder, making them quieter and often easier to handle. These rifles come in various types, including spring-piston, pneumatic, and CO2 models. They can be powered by different mechanisms, affecting their performance and ease of use. Air rifles are popular among beginners and experienced shooters alike due to their versatility and lower cost of ammunition compared to conventional guns.
