These "Power jets", also called nozzles (special screws with holes), are made with the highest quality standards and tolerances.

The different jets are used to calibrate the valve's timing. This means: how long the valve stays open.

The valve of the Leshiy 2, unlike other conventional valves, is always opening to the fully open position. The jets are in charge of closing the valve as fast as we need to achieve the desired powers. In other words, the different jets are closing the valve slower or faster.

We are offering different Jets, and the only difference between them is the diameter of the hole.

Bigger diameter = the valve closes faster = the valve stays open for a shorter time = lower will be the Muzzle Energy of the Leshiy 2.

Smaller diameter = the valve closes slower = the valve stays open for a longer time = higher will be the Muzzle Energy of the Leshiy 2.
