Hatsan Vortex Full Speed Gas Piston Speedfire

Product description

Fits Speedfire and more.
Note that you do NOT need a license to buy the part, but it is with it mounted in an air rifle the air rifle becomes licensed. It is free to buy. It is usually called "Hatsan Vortex licensed Full Fart Gas Piston".
The picture shows an example of a gas piston, not sure this particular item.

The gas piston can be installed instead of the original#%# on the guns above .

This piston is Hatsan's original piston which produces a higher effect than 10J and your air rifle will be subject to a license with this piston fitted as the impact energy exceeds 10J! Changing the piston is easy compared to changing the spring but when the weapon becomes a license requirement it must only be carried out by a trained weapon technician.

The gas piston gives better shooting characteristics compared to a regular spring;
-Significantly much easier to mount in the weapon than a traditional spring
-Less vibrations and a power source that does not create twisting forces, this gives better precision in the weapon
-Quieter
-A more distinct feel and shorter time from firing until the bullet leaves the barrel (locking-time)
-Better effect. A gasspring has better life and keeps the muzzle velocity constant for a longer time.
-A gasspring can be held up for a longer time without losing power.

The pressure (and the muzzle velocity) can adjusted with compressed air through a PCP pump or scuba tube (adapters not included). The piston will be delivered filled and ready to mount.
