Claim Text:
1. An auto regulating gas system for an auto loading firearm wherein the firearm includes a barrel having a bore, at least one gas port, and a muzzle, the gas system comprising: a gas block attached to the barrel to redirect a volume of propellant gases to cycle the auto loading firearm, the gas block including at least one gas port for directing propellant gases received from the at least one gas port of the barrel into the gas system to cycle the auto loading firearm; and a spring-loaded plunger assembly at least partially positioned within the gas block, the plunger assembly including a plunger component having a plurality of gas ports, and a plunger cap at a forward end, the plunger cap having at least one cam pin and at least one cam path, wherein the position of the plunger component within the gas block automatically controls an amount of gas that is allowed to enter the gas system; wherein mounting a suppressor to the muzzle depresses the plunger cap and drives it rearwardly causing the plunger component to rotate as the cam pin travels along the cam path to automatically restrict the volume of propellant gases directed into the gas system through a restricted flow gas port in the plunger component.
