Things to Consider Before Buying

Whether you are getting a CO2 for temporary use or this is something that you are going to keep and want to get the most out of it, be sure to keep the following things in mind before you finalize your purchase.


No matter whether you are to buy an original or replica model, the first thing that you should check is the velocity of the gun. This determines at what speed the pellet or other types of ammo can reach the target.

Air guns with more or less 500 FPS are considered lower-end models that are ideal for plinking, backyard fun, and low range target shooting.

700 FPS models are great for pest control, target shooting, and plinking as well. In most cases, these mid-end air rifles get the work done.

If your shooting purposes require more velocity to make sure the accuracy is uncompromised, go for a high-end model of 800 FPS or more. These are the ones to go for when it comes to hunting small games, long-range target shooting, as well as, pest control.

Cartridge Capacity

CO2 powered air guns use cartridges as a power source, which are known as compressed gas. Usually, these models come with a 12 gm of CO2 cartridge. You don’t need to refill it every time when you start a shooting session. 12 gm of capacity will allow you to shoot 50 shots on average before you need to refill again.

There are some guns that come with 90 gm of cartridges. These require much less refilling. Such cartridges easily last for 300 shots at least until the gun requires refilling.


Regardless of the specs, your air gun comes with, triggers influence the overall shooting experience in both positive and negative ways.

Triggers are either of one stage action or two-stage action.

  • Single Stage

Single-stage ones are ideal for plinking and similar purposes where you need to shoot quickly. This particular trigger system makes short-distance shooting very convenient and friendly.

  • Two Stage

When shooting accuracy as well as precision is the requirement, look for an air gun that comes with a two-stage action trigger. You will get enough time to aim at the target, and shoot with great precision.

Some models come with an adjustable trigger mechanism that allows you to customize the trigger according to your preference and style.

Semi-Auto or Single-Shot

CO2-powered guns come in semi-auto and single-shot functions.

  • Semi Auto

Semi-auto models self reload the next round of the pellet if you use a repeater. You can conveniently fire each round pulling the trigger every time. If you need something quick and fast, look for a semi-auto air gun. These perform great for pest control and plinking.

  • Single Shot

Single-shot models, on the flip side, require to reload the gun every time before firing a pellet. Although these guns are less convenient, if you don’t want to spend much on an air gun, a single-shot air gun is the only option here.


If you are to take the rifle in the wild for hunting small game, make sure the construction is all-weather resistant. This will make sure your gun is durable enough to withstand impacts and abuses, and at the same time, the metal parts are rust and corrosion-resistant.
