Air guns, also known as pellet guns or BB guns, are firearms that use compressed air or gas to propel projectiles. They are a popular choice for recreational shooting and other activities because of their versatility and relatively low cost. Here are some of the different types of air guns:

1. BB guns: BB guns are air guns that shoot small metal balls called BBs. They are usually designed for target shooting or pest control and are available in a range of sizes and styles.

2. Pellet guns: Pellet guns are air guns that shoot small, cylindrical projectiles made of lead or other materials. They are typically more accurate and powerful than BB guns and are often used for hunting and long-range target shooting.

3. Pneumatic air guns: Pneumatic air guns use compressed air as the propellant. They can be powered by a hand pump or a compressor and are often used for target shooting and pest control.

4. CO2 air guns: CO2 air guns use a small cylinder of compressed CO2 gas as the propellant. They are popular for their convenience and are often used for target shooting and pest control.

5. Spring-piston air guns: Spring-piston air guns use a spring-loaded piston to compress air in a chamber. When the trigger is pulled, the spring is released and the compressed air drives the piston forward, propelling the projectile out of the barrel. Spring-piston air guns are known for their reliability and are often used for hunting and long-range target shooting.

6. Precharged pneumatic (PCP) air guns: PCP air guns are pneumatic air guns that are charged with compressed air before use. They have a high-pressure air tank that can be filled with a compressor or hand pump, and they can hold a charge for a longer period of time than other pneumatic air guns. PCP air guns are known for their accuracy and power and are often used for hunting and long-range target shooting.

7. Break barrel air guns: Break barrel air guns are air guns that have a hinged barrel that can be "broken" open to load the projectile. They are easy to use and are often used for hunting and target shooting.

Overall, there are many different types of air guns to choose from, depending on your needs and preferences. No matter what type of air gun you choose, it is important to handle it responsibly and follow proper safety guidelines.
