PCP Archives

finalChoosing the right air source for your PCP gun can be tricky. There is more than one way to fill your rifle and each of them has both advantages and disadvantages. If you don’t take a step back and consider all the potential options, chances are you are going to end up with frustration because everyone is different and there is no one-size-fits-all solution. In this post, we will take a close look at the pros and cons of 3 common ways to fill your gun: hand pump, scuba tank and carbon fiber tank.

Hand pump

hand pump

A hand pump is generally the same as the bicycle pump, but instead of pumping the tire, you pump the air reservoir of the PCP gun. It’s recommended that you do not pump more than 5 minutes and let the pump cool down 15 minutes between pumping sessions to prevent overheating. A modern hand pump can get to 3000 psi (pounds per square inch) When you start to pump, the beginning is easy and you can even pump with one hand to get to 1000 psi. But from 2500 psi on, you begin to feel strong resistance so it’s best to leverage your body weight to pump at this point.

Is PCP air rifle the best choice?

PCP air gun is one of five types of air rifles. In the market today, PCP air guns have become more and more popular and are sought-after .In this post, we will take an in-depth look at a PCP rifle, what it is, how it works, its pros and cons and whether you should buy one at all.

Where did PCP Come From?

Contrary to common beliefs that PCP rifles have been made only recently, they actually appeared the first time in the mid-1500s. The first who made the most of them are Austrians. The Austrians had thousands of PCP guns for their army in the war between them and France. Their guns were .26 caliber, 24 shots per minute repeaters in the time that a repeating firearm didn’t even exist. It gave them a huge advantage over Napoleon’s army who only could make 3 shots per minute due to the loading difficulty of the gun powder. After that time, PCP guns continued to be made. The manufacture of PCP air gun stopped after World War 1 and was revived in .177 and .22 caliber around 1980.

How it works?

PCP stands for Pre-charged Pneumatic, which means that the compressed air is put into the gun in advance before it is shot. Basically, it’s the air gun with a hollow tube containing high-pressurized air. Typically, the air is compressed at 3000 psi (pounds per square inch), sometime less, sometime more. There are multiple ways to fill the air reservoir.  You can use hand pumps, scuba tanks or carbon fiber tanks. Once the gun is filled to a certain pressure level, it is ready to use. The firing cycle of PCP happens as follows: When you pull the trigger, the firing valve opens and releases compressed air inside the barrel. The compressed air has no way to go but behind the pellet and the pellet is pushed out of the barrel due to propellant force of the compressed air. After that, a small amount of air and pressure in the reservoir are reduced.
