Abstract
A gas operating system for a firearm renders the firearm capable of firing a wide range of shot loads by passively or automatically compensating for different shot loads. The firearm includes a plurality of ports formed in the firearm barrel, and corresponding ports formed in a gas cylinder of the gas operating system. The ports tap gases generated during firing which are used to cycle the firearm. When firing different cartridge loads, differing combinations of the ports are selectively at least partially blocked or otherwise obstructed by the cartridge casing according to the size of the cartridge.
