Power jets are necessary to calibrate the valve's timing, that is, how long the valve stays open. When the Leshiy 2 fires, the valve always opens completely - we use power jets to close the valve as fast as we need to achieve desired power levels. The longer the valve is open the more power is transferred; the bigger the diameter, the faster de valve closes, and the lower will be the muzzle energy of your Leshiy 2.
These 2.0-millimeter power jets are tailored to make your Leshiy 2 achieve 12FPE. We have selected these for those wanting to reach that power limit and not exceed it. Like all the other power jets, these are made with the highest quality standards and tolerances.
