So what is the role of the gas piston in an AK-47 and just how critical a component is it? In the AK-47 gas-operating system, a portion of the high-pressure gases from a fired cartridge is vented through a gas tube, where it forces the piston rearward. As the piston moves rearward, it acts upon the bolt carrier and forces both it and the bolt rearward. The rearward movement of the bolt provided for the extraction and ejection of a spent cartridge case and the chambering of a new cartridge upon being thrust forward by the recoil spring. In other words, the gas piston is absolutely necessary in any semi-automatic or selective-fire AK-47 or Kalashnikov-patterned rifle.
