PKM system of operation?

Explanation:
The PKM operates on a gas-driven cycle where some of the hot gases from firing are tapped through a port to drive a piston that cycles the action. That gas blast provides the impulse to push the bolt rearward, unlock, extract, eject, feed the next round, and then lock again for the next cycle. This design, known in practical terms as a gas-operated system, is built for rapid, sustained firing, which is why it’s favored for a belt-fed machine gun. The “auto only” part means the standard PKM is configured for automatic fire and does not use a semi-automatic fire mode in its typical setup. In short, the weapon uses a gas blast to cycle the action and is designed for continuous automatic fire.
