Pressure controlled inertia system for automatic fire weapons

A method of operating a pressure controlled inertia system for automatic fire weapons comprising the following steps:

• moving a sliding handle forward by an inertia force,
• wherein a holder causes a release of a stored energy from an energy storage spring when a lock is contacted and a plunger is freed from contact with the holder,
• wherein a force of the energy storage spring overcomes a friction force and opens the lock when a gas pressure drops to an optimum level required for a rifle to operate regardless of a cartridge fired at different forces,
• pushing a mechanism and the sliding handle backward when the gas pressure falls to the optimum level required for the rifle to operate
• until a spring setter is contacted, wherein the spring setter is activated by pulling a trigger to a position until an energy storage spring pin is contacted,
• wherein a kinetic energy of the mechanism and the sliding handle is absorbed by an energy storage spring through the energy storage spring pin,
• wherein a holder spring causes the holder to contact the plunger and store an energy absorbed by the energy storage spring preventing the energy from escaping,
• wherein the sliding handle is spaced from the mechanism by the distance adjustment spring,
• wherein a knob spring causes the lock to enter a cap barrel and lock the rifle to make the rifle ready for a new firing.
