Types of Compressed Air, Nitro Piston and Pneumatic Weapons, Continuing with the topic related to the types of compressed air weapons, today we will talk about the Gas Spring and the Pneumatic

Gas Spring Arms

A well-known type of compressed air weapons are those of Gas Spring, these are of recent generation, some names that they give are:

Gas piston
Gas Strut
Nitro piston

This, unlike the mechanical spring. In this type of weapon the spring is replaced by a pressure piston pump, independent and without outlet, in this case the air or

Pressurized inert gas, Nitrogen is often used, this is kept hermetic and sealed inside the pressure cylinder.

How does it work?

When the shooter cocks the gun, the gas or air inside the cylinder is compressed much more by the action of the piston, this causes the storage of energy potential and becomes a pneumatic accumulator actuator, ready to transfer the accumulated energy to the pellet.

These models are of high quality since the manufacturing processes must be of high precision because the seal of the pressurized chamber must withstand high pressures and it must be low-friction to avoid overheating.

Advantages of piston airguns

These models can keep the weapon cocked and ready to fire for a long time, without a spring to fatigue, weaken or suffer torsion.

As there is no torsion, as there is no spring as such, the recoil pattern of the weapon is smooth and silent.

The blocking time is faster, which means that since the trigger is pressed and the pellet is fired, the time is much shorter, which gives a better response when recharging.

In cold climates, piston-actuated airguns perform much better, as they do not have metal springs that respond to changes in temperature.

Sudden changes in temperature, as Small Game hunters know, can cause the spout tube to freeze.

In this type of weapon, the mechanical vibrations of the springs are almost non-existent, neither lateral nor vertical, so the shot is cleaner and safer.

Pneumatic type weapons

These types of airguns are powered by using the pneumatic potential energy within the compressed air, which is pressurized beforehand and stored inside the gun. This potential is then released through valves during firing.

Single and multi-stroke pump guns use a built-in manual pump to pressurize the air in a reservoir within the gun.

The reservoirs of the pre-charged pneumatic guns are filled from an external source using a high pressure support pump or by decanting air from a larger scuba cylinder.
