When it comes to powering airguns, CO2 is a popular choice among shooters due to its convenience and ease of use. However, not all air rifles and pistols require CO2 to function. We explore the different types of airgun powerplants and help you understand whether CO2 is essential for your shooting needs.

Understanding CO2 Airguns

CO2 airguns rely on compressed carbon dioxide gas to propel airgun ammunition such as pellets, or BBs, out of the barrel. When the trigger is pulled, a small amount of CO2 is released, pushing the projectile forward.

One of the main advantages of CO2 airguns is their ability to provide consistent power, shot after shot. Unlike spring-powered guns that require manual cocking, CO2 air rifles and pistols can fire multiple shots in rapid succession without any loss of velocity. This makes them ideal for plinking and target shooting.

However, CO2 airguns do have some limitations. The CO2 cartridges can only hold a finite amount of gas, which means you’ll need to replace them periodically. Additionally, CO2 is sensitive to temperature changes, which can affect the gun’s performance in cold weather.

Exploring Other Airgun Powerplants

While CO2 is a popular choice, it’s not the only option available for powering airguns. Let’s take a look at some of the other common powerplants:

Spring-Powered Airguns

Spring-powered airguns, also known as springers, use a compressed spring and piston to generate air pressure behind the pellet. When the gun is cocked, the spring is compressed, and when the trigger is pulled, the spring is released, driving the piston forward and compressing the air in the compression chamber.

Spring-powered airguns are known for their simplicity and reliability. They don’t require any external power source, making them a great choice for shooters who want a low-maintenance gun. However, they do require manual cocking between each shot, which can be tiring over extended shooting sessions.

Pre-Charged Pneumatic (PCP) Airguns 

PCP airguns use compressed air stored in an onboard reservoir to propel pellets. The reservoir is typically filled using a high-pressure hand pump or air compressor and can hold enough air for multiple shots before needing to be refilled.

PCP air rifles and pistols are known for their high power and accuracy. They can achieve velocities that rival those of CO2 guns, but without the temperature sensitivity. However, they do require more maintenance than other types of airguns, and the initial cost of a PCP setup can be higher due to the need for a pump or compressor.

Pump Pneumatic Airguns

Pump pneumatic airguns use a built-in pump to compress air in a small reservoir. The shooter must pump the gun multiple times to build up enough pressure for each shot.

Pump guns are a good choice for shooters who want the power of a PCP airgun without the need for an external pump or compressor.

However, they do require more effort to shoot than CO2 or spring-powered guns and the number of shots per pump can vary depending on the model.

Choosing the Right Powerplant for Your Needs

So, do airguns need CO2? The answer depends on your specific shooting requirements and preferences. If you prioritise convenience and rapid-fire shooting, a CO2 airgun may be the best choice for you. Brands like Umarex and Crosman offer a wide range of CO2-powered air rifles and pistols for plinking and target shooting.

On the other hand, if you’re looking for a low-maintenance gun for occasional use, a spring-powered airgun may be a better fit. And if you’re a serious shooter who demands the highest levels of power and accuracy, a PCP airgun may be worth the investment.

Ultimately, the key is to choose a powerplant that aligns with your shooting goals and budget. Consider factors like the type of shooting you’ll be doing, the level of maintenance you’re willing to perform, and the initial cost of the gun and any necessary accessories.
