Types of Compressed Air Weapons, Preloaded Pneumatic Guns or PCP


CHARACTERISTICS AND OPERATION


These types of compressed air weapons are very particular, they work using an internal tank preloaded from an external air source, which can be from a compressed air cylinder or by manual loading with a high pressure foot pump.
The operation of the weapon is based on having shots available until the pressure exerted by the pneumatically compressed gas is exhausted.


Shooting Action


When the trigger is pressed, the hammer of the compressed air weapon presses a valve that releases an amount of gas from the reservoir that is attached to the body of the weapon, this volume of gas is already pre-established and calculated for a shot, it will drive the pellets through the barrel of the airgun, causing it to be fired at high speeds.


Types of PCP compressed air weapons according to the valve.

Depending on the design of the discharge valve, PCP compressed air guns can be classified into two types:

  • Unregulated: Without a mechanical or electronic regulator.
  • Regulated: They have a mechanical or electronic valve regulator actuator, which allows an adjustment in the force applied to the pellet.


Gases used for pneumatic compression in PCP.


The most recent models, in addition to using compressed air, have begun to use inert gases such as helium and nitrogen, the latter widely used in the models that achieve the highest speeds.

Initial Cost Versus Maintenance Cost


Because of the need to incorporate an additional tank, the initial cost of the equipment is a little higher than a spring or pump compressed air weapon as we have seen in other articles, but the maintenance cost is lower. So in the long run, saving can be quite substantial.


This happens because they have practically no movement and friction of mechanical parts, which implies less wear on the body of the weapon and fewer parts that can be damaged.


Regarding the quality of the shot, this type of airgun has a much smoother recoil, so the shot is more accurate.
With a single charge of air or inert gas, you can take up to 100 shots, of course, depending on the tank that is built into your airgun.

Conclusion


Well-designed PCP will show good shot-to-shot consistency over a long period, as the air reservoir is depleted. Other PCP rifles and pistols are regulated, that is, the trigger valve operates within a secondary chamber separated from the main air reservoir by the regulator body.


The regulator maintains the pressure within this secondary chamber at a set pressure until the pressure in the main reservoir drops to the point where it can no longer do so.


As a result, shot-to-shot consistency is maintained for longer than in an unregulated rifle, and the weapon can also produce more shots due to reduced pressure waste from the reservoir.
