Co2 air gun

Investing in the right air gun is what can help you fall in love with the sport of air gunning. You can be forgiven for thinking there are only two types; spring piston or precharged pneumatic, as the argument of which of these two is better tends to overshadow the other types. These two are the most popular with many air gunners, but we are here to shed light on the other types too.

Precharged pneumatic air guns

Precharged pneumatic (PCP) guns can be dated back more than 300 years, and their popularity has grown within the last 20 years. Many shooters are won over by PCPs as they offer accurate, recoilless shooting, with little cocking effort. You also get lots of shots with one charge.

PCPs power source is a cylinder of compressed air. Every time a shot is taken, air is released under pressure from the cylinder by the main firing valve and this propels the pellet down the barrel. A PCP also needs to be recharged with gas, from a diver’s bottle or pumped manually. Buying all the equipment does add an extra cost to PCP air guns and rifles, but it is also a very cheap form of shooting.

Why not take a look at the Brocock air rifles for sale at Surplus Store, many of which are PCP?

Multi-stroke or single-stroke air guns

These are a variation of PCP and are sometimes called pump-ups, as that is what you have to do to charge them with enough compressed air to power the pellet out of the barrel at a decent pace. The first variation, multi-strokes are only of moderate power, and accuracy is not its strong point. The other, single-stroke air guns, are more accurate as only one pump is required to compress enough air to propel the pellet. The single-stroke also lack recoil and generate consistent shots, making them a favourite for top shooters. The multi stroke pump guns we have stocked at Surplus Store tend to be full power, but less accurate (lower quality) and the single strokes tend to be lower power, but more accurate (higher quality).

Spring-piston air guns

These are probably the most popular type of air gun. Most air gunners start off with a break barrel, spring piston air gun because they are simple to use and less expensive. All that you have to do is charge the spring, by either opening the gun at the breech, or cocking them from a side or under lever when the barrel is fixed. Having a fixed barrel means the alignment is constant and improves accuracy. The main drawback of shooting with a springer is the recoil, and this can also affect their accuracy.  Spring based rifles are also the loudest of the bunch and as most of the noise comes from the sound of the internal piston not the muzzle moderators. Suppressors (silencers) don’t work nearly as well on spring based rifles.

However, springers are popular as they are self-contained. You have no need of a pump or diver’s bottle to re-charge the rifle, which provides more flexibility when out and about. Another advantage is that they are relatively easy to service at home too.

Co2-powered air guns

This type of air gun uses Co2 cylinders as its power source, and all semi-automatic air guns are powered this way. The advantage of Co2 air guns is that they offer the ability to fire shots as fast as you can pull the trigger, and there is no need to pump. The disadvantage is that these air guns are not as powerful as other types, they don’t always operate well in cold conditions and due to the liquid propellant can be a little more inconsistent than the rest. The air guns rely on the Co2 in the cylinder expanding when the trigger is pulled, which happens slower in cold conditions.

Your choice

The most important fact about the various air gun power systems is that there is one which will suit your needs, and all you need to do is some research before you buy. At Surplus Store, we are also happy to help out with your choice.
