A firearm gas redirection assembly directionally directs discharged gases from a barrel towards a bolt frame, and uses the energy from discharged gases to force a bolt rearwardly in an action. The barrel has an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end. The forward end of barrel forms gas vents. The barrel is fixed motionless on the frame of the weapon. A jet nozzle concentrically couples around the barrel and integrates with a bolt frame. The jet nozzle has inner and outer jet sidewalls and a jet nozzle edge. The inner jet sidewall and outer barrel sidewall form a gas space that is in communication with the bolt frame. Discharge of firearm forces high velocity gas through gas vents that form in the barrel, through gas space, and finally against the jet nozzle edge. This forces bolt frame rearwardly.
