Air rifles have gained popularity over the years as versatile and powerful tools for various activities such as hunting, pest control, and target shooting. An air rifle is a type of gun that fires projectiles using energy from compressed air or other gases that are mechanically pressurized, distinguishing it from firearms that use gunpowder to propel bullets. These rifles come in multiple forms, such as air pistols and long air rifles, catering to various user preferences and purposes.

One of the major differences between air rifles lies in how the air is compressed and stored within the gun. These guns are often considered a safer and quieter option compared to firearms, as they do not require combustible propellants nor produce loud explosions upon firing. Additionally, modern air rifles are available in various calibers and power outputs, making them suitable for a diverse range of tasks and enthusiast levels.

Types of Air Rifles

There are several types of air rifles available for various purposes. In this section, we will discuss four main types: Spring Piston, Gas Piston, Pre-Charged Pneumatic (PCP), and CO2 air rifles.

Spring Piston

Spring Piston air rifles, also known as break barrel air rifles, are the most common type of air rifle. They operate using a simple spring-loaded mechanism. When the rifle is cocked, a powerful spring is compressed, storing energy. Upon pulling the trigger, the spring is released, forcing air through a narrow chamber and propelling the pellet down the barrel. Spring Piston air rifles are popular because they are affordable, easy to maintain, and do not require any additional power sources or props.

Gas Piston

Gas Piston air rifles, sometimes called gas ram or gas spring rifles, function similarly to Spring Piston air rifles. However, instead of a mechanical spring, they use compressed gas, often nitrogen, to store energy. Gas Piston air rifles provide several advantages over their Spring Piston counterparts. They have less recoil, are less affected by temperature fluctuations, and often last longer due to less wear on internal components. On the downside, they tend to be more expensive than Spring Piston air rifles.

Pre-Charged Pneumatic (PCP)

Pre-Charged Pneumatic (PCP) air rifles use a high-pressure air reservoir to propel pellets. These rifles are filled using a hand pump, scuba tank, or specialized air compressor. PCP air rifles offer unparalleled power and accuracy, making them popular among competition shooters and hunters pursuing larger game. They also have minimal recoil and often feature multi-shot capabilities. However, PCP air rifles can be expensive and require additional equipment for filling, making them less accessible for casual users.


CO2 air rifles use small, pre-filled CO2 cartridges as a power source. When the trigger is pulled, a valve opens, releasing a burst of compressed CO2 gas that propels the pellet down the barrel. CO2 air rifles are popular for their convenient power source, allowing for quick and easy shooting sessions without the need for pumps or external tanks. They are often used for plinking, target shooting, and small game hunting. However, the power and accuracy of CO2 air rifles can vary, as temperature fluctuations may cause inconsistencies in performance. Additionally, the ongoing cost of CO2 cartridges can add up over time.

Power and Velocity

Muzzle Velocity

Air rifles are popular for their power and velocity, which are crucial factors in determining their effectiveness. Muzzle velocity refers to the speed at which a projectile exits the barrel of the air gun. This is usually measured in feet per second (fps). The muzzle velocity of air rifles can vary, with some models reaching speeds of up to 1,250 fps.

Power Sources

There are different power sources for air rifles, and these can affect the power and velocity at which they operate. Some common power sources include:

  1. Spring-piston: These air guns utilize a spring-powered piston to compress air in a cylinder. When the trigger is pulled, the compressed air propels a pellet forward.
  2. Gas piston: A gas piston air gun functions similarly to a spring-piston, but instead of a mechanical spring, it uses a gas-filled cylinder to compress the air.
  3. Pneumatic: Pneumatic air rifles require an external source of compressed air, either from a hand pump or a reservoir. There are two main types of pneumatic air rifles: single-stroke and multi-pump.
  4. Pre-charged pneumatic (PCP): PCP air guns feature a high-pressure air reservoir that holds the compressed air. When the trigger is pulled, a regulated amount of air is released, propelling the pellet. The reservoir can be filled using a hand pump or a specialized filler.

Shot Count

Shot count refers to the number of shots that can be fired with consistent power and accuracy from an air rifle before the pressure in the reservoir drops significantly. In pre-charged pneumatic (PCP) air rifles, the shot count is an essential factor to consider, as it dictates how many shots can be taken before needing to refill the reservoir. Factors like the valve design, fill pressure, and airflow through the transfer port can influence the shot count of an air rifle.

Pellet Calibers and Projectiles


BBs are small, spherical projectiles typically made from steel and coated in copper or zinc for corrosion resistance. They are commonly used in air rifles and pistols designed for BB ammunition, and they come in a standard caliber of 0.177 inches (4.5mm). BBs are lightweight and have limited accuracy, making them suitable for casual plinking and short-range shooting.


Airgun pellets are the most popular and versatile type of ammunition for air rifles and pistols. They come in various calibers, including 0.177, 0.20, 0.22, and 0.25 inches. Pellets are primarily made from lead but can also be constructed from tin or a combination of several metals. The diabolo shape, which consists of a head (where the majority of the mass is) and a hollow tail, is the most common pellet design.

Pellets offer better accuracy and energy retention than BBs, making them suitable for target shooting, pest control, and small-game hunting. Factors such as weight, shape, and composition can significantly affect a pellet’s performance. It’s essential to experiment with different pellet types to find the most suitable projectiles for specific airguns and shooting purposes.


Airgun slugs are solid, cylindrical projectiles that come in various calibers and weights. They offer improved external ballistics, long-range capabilities, and outstanding terminal performance compared to pellets and BBs. Slugs are usually made from lead or other soft metals, allowing them to expand upon impact for maximum energy transfer.

Slugs are commonly used in high-powered, pre-charged pneumatic (PCP) air rifles designed to handle such ammunition. These airguns often feature rifled barrels for better stability and accuracy. Slugs are ideal for hunting and long-range shooting disciplines where penetration and energy retention are critical.


Airgun darts are specialized, needle-like projectiles designed for specific airgun models. They consist of a long, thin metal point with a plastic or metal cone attached for stabilization. Darts provide unparalleled penetration capabilities but limited accuracy, making them suitable for target shooting and competitions where precision penetration is necessary.

Please note that not all airguns are compatible with darts, and they should only be used in models designed to safely handle such projectiles. Using darts in an incompatible airgun can result in damage to the barrel or other internal components.

Overall, the choice of airgun ammunition varies based on the desired shooting discipline, airgun type, and personal preferences. Each projectile option offers distinct advantages and limitations, so it’s essential to understand the differences between BBs, pellets, slugs, and darts when selecting the appropriate ammunition for your air rifle or pistol.

Accuracy and Shot Placement


Air rifle accuracy refers to the ability of an air rifle to shoot ammo and hit the intended target consistently. When aiming at a target, consistency and precision are crucial in both target shooting and competition scenarios.
